Storm简介Storm简介•实时计算需要解决一些什么问题•实现一个实时计算系统•Storm基本概念•Storm使用场景•Storm分组机制Storm简介•实时计算需要解决一些什么问题伴随着信息科技日新月异的发展,信息呈现出爆发式的膨胀,人们获取信息的途径也更加多样、更加便捷,同时对于信息的时效性要求也越来越高。
举个搜索场景中的例子,当一个卖家发布了一条宝贝信息时,他希望的当然是这个宝贝马上就可以被卖家搜索出来、点击、购买啦,相反,如果这个宝贝要等到第二天或者更久才可以被搜出来,估计这个大哥就要骂娘了。
再举一个推荐的例子,如果用户昨天在淘宝上买了一双袜子,今天想买一副泳镜去游泳,但是却发现系统在不遗余力地给他推荐袜子、鞋子,根本对他今天寻找泳镜的行为视而不见,估计这哥们心里就会想推荐你妹呀。
其实稍微了解点背景知识的码农们都知道,这是因为后台系统做的是每天一次的全量处理,而且大多是在夜深人静之时做的,那么你今天白天做的事情当然要明天才能反映出来啦。
Storm简介•实现一个实时计算系统全量数据处理使用的大多是鼎鼎大名的hadoop或者hive,作为一个批处理系统,hadoop 以其吞吐量大、自动容错等优点,在海量数据处理上得到了广泛的使用。
但是,hadoop不擅长实时计算,因为它天然就是为批处理而生的,这也是业界一致的共识。
否则最近这两年也不会有s4,storm,puma这些实时计算系统如雨后春笋般冒出来啦。
先抛开s4,storm,puma这些系统不谈,我们首先来看一下,如果让我们自己设计一个实时计算系统,我们要解决哪些问题。
Storm简介•实现一个实时计算系统低延迟。
都说了是实时计算系统了,延迟是一定要低的。
高性能。
性能不高就是浪费机器,浪费机器是要受批评的哦。
分布式。
系统都是为应用场景而生的,如果你的应用场景、你的数据和计算单机就能搞定,那么不用考虑这些复杂的问题了。
我们所说的是单机搞不定的情况。
storm教程
storm教程Storm是一个开源的实时大数据处理系统,由Apache基金会开发和维护。
它旨在解决实时处理大规模数据的需求,可以用于处理实时流数据、分布式计算和分布式消息传递。
本教程将向您介绍Storm的基本概念和使用方法。
Storm的基本概念包括Topology、Spout、Bolt和Stream。
Topology是一个实时计算任务的有向无环图,由一系列Spout和Bolt组成。
Spout用于从数据源读取输入数据,并将数据发送给Bolt进行处理。
Bolt是具体的计算单元,可以执行各种数据处理操作。
Stream是数据在Spout和Bolt之间传递的流。
首先,您需要配置Storm集群。
您可以在多台服务器上部署Storm,并通过ZooKeeper来进行协调和管理。
建议使用分布式文件系统来存储Storm的配置和数据。
接下来,您需要按照以下步骤编写和运行一个Storm拓扑:1. 创建一个Topology对象,并设置它的名称。
2. 创建一个Spout对象,并实现Spout接口的nextTuple方法。
在这个方法中,您可以从数据源读取数据,并将每条数据发送给下一个Bolt。
3. 创建一个或多个Bolt对象,并实现Bolt接口的execute方法。
在这个方法中,您可以对接收到的数据进行处理,并发送处理结果给下一个Bolt。
4. 将Spout和Bolt对象添加到Topology中,并定义它们之间的连接关系。
5. 配置Topology的并行度,即每个Bolt的并行处理数量。
6. 提交Topology到集群中运行。
您可以使用Storm提供的命令行工具来提交和监控Topology的运行状态。
在拓扑运行期间,您可以根据需要进行监控和调试。
Storm提供了各种监控工具和命令,包括Storm UI、Log Viewer和Storm Shell等。
此外,Storm还提供了可扩展性和容错性机制。
当集群中的节点发生故障时,Storm可以自动重新分配任务并保证数据的完整性。

Should you find yourself in such a situation, we have drawn up the following checklist of general issues and causes that should help you shoot your way out of trouble without seeking further assistance.No or poor quality picture?1) Device Connection - Are you connected and powered? Double check all HDMI and 5v power connections are firmly inserted into correct ports and that all devices are powered.2) Cable Length – Your signal could be struggling to transmit over the length of your HDMI cable? If possible, try using a shorter HDMI cable.3) Signal strength – the use of cable joins, stranded patch panels, wall outlets and stranded patch leadsas interconnects between them, can significantly reduce signal strength. Use solid core, straight-through connections wherever possible.4) Resolution - If you reduce the resolution of the source, do you get a picture? If so, this suggests a conflicting resolution between source and display ora bandwidth capacity issue with your cable. Check all inputs and outputs share the same resolution and make sure the signal is being successfully transmitted the full length of your HDMI cable.5) Cable quality and condition – HDMI cable/ connectors can be easily damaged and the quality of material can vary, especially in lower price brackets. Successful transmission of video, audio and control can all be affected by cable and termination quality. Always use good quality leads and cables. Should transmission problems be experienced, try swapping cables/leads for those already working to see if this improves your image to identify cable issue as source of problem.6) Blu-Ray, 3D - is the equipment used 3D enabled/ compatible? Is a 3D disc being played in a 3D enabled Blu-ray player or through a compatible AV receiver? Are resolutions between source and display compatible with adequate cable bandwidth for the larger 3D transmissions?7) 4K - Are you trying to pass a 4K signal? Ensure connected devices are 4K enabled, correctly configured and outputting compatible transmissions4K: 3840 (UHD) or 4096 (DCI) 2160 @ 30Hz with chroma (colour) subsampling rate of 4:2:21080p: 1920x1080p, 60Hz (if problems are experienced at 60Hz, try lowering to 50Hz)8) Power LED off - Check power supply is onand cables are connected properly and of required specification9) Input or Output LED off – Check power is supplied to all connected devices and cables are connected properly and of required specification10) Display not showing image – Check all devices are turned on and cables are connected properly and of required specification and corresponding Output LED on splitter is lit. Also check display and source are operating properly and Source is outputting a signal, making sure devices support HDCP.Ensure the length of HDMI cables between devices are within limits – see Specification section for details.If compatibility issues are suspected between display and splitter, swap out for a display you know is fully functional with the system.11) Display device displays ‘HD ‘noise’ such as picture ‘snow’ or ‘mosaic’ – signifies a failure to fully establish a signal and can often be caused by excessive cable lengths.Check power is supplied to all connected devicesand cables are connected properly and of required specification.Ensure the display device supports HDCPCheck input source does not have the same picture issues, if so, check settings of source device or replace source.Ensure the length of HDMI cables between devices are within limits – see Specification section for details.Try swapping or shortening your HDMI cable – if the problem continues on the same output, turn off all equipment and swap your signal carrying cables at both ends.6FAQAre WyreStorm products compatible with HDMI 1.4?HDMI 1.4 refers to a list of ‘features’ that a device is capable of supporting, including Ethernet channel, return audio channel, 3D etc.Due to the continuously evolving nature of the technology, HDMI Licensing LLC have now decided to simplify terminology by testing and referring to cable in terms of STANDARD or HIGH-SPEED rather than versions 1.3, 1.4 etc.STANDARD (or “category 1”) HDMI cables performat speeds of 75Mhz or up to 6.75Gbps, which is the equivalent to a 720p/1080i signal – These HDMI cables are NOT recommended.All WyreStorm equipment support HIGH-SPEED (or “category 2”) HDMI cables that have been tested to perform at speeds of 340Mhz or up to 10.2Gbps, which is the highest bandwidth currently utilized over an HDMI cable and can successfully handle 1080p and 4K signals including those at increased color depths and/or increased refresh rates from the source. High-Speed cables are also able to accommodate higher resolution displays, such as WQXGA cinema monitors (resolution of 2560 x 1600).What about screens with different resolution capabilities?When sending a signal point to point a TV will communicate its capabilities to the source, which will then output a compatible signal the display can accept (i.e. 1080p Stereo audio). Switchers or splitters do not scale per output but instead negotiate with the source a signal that all screens are capable of supporting.If a switcher or splitter distribution is used with different resolution combinations of 4K, 1080p or 1080i screens, the resultant image will likely be the lowest resolution capable of being received across all screens.For combined 4K and 1080p HD distributions, a WyreStorm EXP-SCL-DAC-4K scaler between receiver and display is required to scale down 4K transmissions to 1080p 24fps for HD screens and upscale 1080p to 4K 30Hz for UHD displays. See for more details How does the Transmission device handle HDCP?HDCP (High Definition Copyright Protection) is a feature built in to HDMI devices to prevent theft of or illegal distribution of HD content.Unlike competing products, WyreStorm equipment is legal and comply with HDCP regulations by assigning a “key” to any display connected to an HDMI device. This doesn’t change when connecting to an extender, receiver splitter or matrix switch; rather keys are duplicated or more keys are assigned.Clean this unit with a soft, dry cloth only. Never use alcohol, paint thinner or other harsh chemicals.1. Damage requiring service: This unit should be serviced by a qualified service personnel if:• The DC power supply or AC adaptor has been damaged.• Objects or liquid have gotten into the unit.• The unit has been exposed to rain.• The unit does not operate normally or exhibits a marked change in performance.• The unit has been dropped or the cabinet damaged.2.

storm的5个主要术语
Storm的5个主要术语1. Topology(拓扑)在Storm中,Topology(拓扑)是指一个分布式计算任务的计算网络结构。
它定义了数据流如何在各个组件之间流动,并规定了每个组件的处理逻辑。
拓扑由Spouts和Bolts组成,Spouts用于数据源输入,而Bolts用于数据处理和转换。
拓扑中的每个组件都可以并行执行,这使得Storm能够实现高效的分布式计算。
拓扑还可以通过设置任务的并行度来控制整个计算任务的性能和可伸缩性。
2. Spout(喷口)Spout(喷口)是Storm中用于读取数据源的组件。
它负责从外部数据源获取数据,并将其发送给Bolts进行进一步处理。
Spout可以从多种数据源中读取数据,例如消息队列、数据库、文件系统等。
Spout通常是一个无状态的组件,它不会对接收到的数据进行任何处理或转换。
它只是简单地将数据发送给下游的Bolts进行处理。
Spout还可以设置可靠性机制,以确保即使在失败或崩溃时也不会丢失任何数据。
3. Bolt(螺栓)Bolt(螺栓)是Storm中用于处理和转换数据的组件。
它接收来自Spouts的数据,并根据预定义的逻辑进行处理,然后将处理结果发送给下游的Bolts或外部系统。
Bolt可以执行各种任务,例如过滤、转换、聚合和存储数据。
它还可以与其他Bolts进行交互,以实现更复杂的计算逻辑。
Bolt也可以设置可靠性机制,以确保处理结果的完整性和一致性。
4. Stream(数据流)Stream(数据流)是Storm中用于在拓扑中传输数据的抽象概念。
它代表了一连串有序的数据元素,这些数据元素从Spouts流向Bolts,并在各个组件之间进行传递和处理。
数据流可以分为多个分支,并且可以通过设置字段分组来控制数据在拓扑中的路由和分发方式。
每个Bolt都可以定义自己感兴趣的字段,并根据这些字段对接收到的数据进行分组。
Storm使用高效的消息传递机制来实现可靠和低延迟的数据流传输,这使得它非常适合处理大规模实时计算任务。

二、Storm的基本概念在深入探讨Storm的原理之前,我们需要先了解一些Storm的基本概念。
1. Topology(拓扑)在Storm中,拓扑(Topology)是指实时计算的一个任务或应用程序。
拓扑由多个组件组成,每个组件负责一部分计算任务。
拓扑中的组件可以是数据源、数据处理器、数据存储器等。
拓扑可以包含多个层次和多个任务,形成一个复杂的计算图。
2. Spout(喷口)Spout是拓扑中的数据源组件,它从外部数据源接收数据,并将数据发送给下游的Bolt组件。
Spout可以从文件、消息队列、Socket等数据源中读取数据,并实时地将数据发送给Bolt进行处理。
3. Bolt(螺栓)Bolt是拓扑中的数据处理组件,它接收Spout发送的数据,并对数据进行处理。
Bolt可以执行各种计算任务,例如过滤、聚合、计数等。
Bolt可以有多个实例,每个实例只处理一部分数据,并可以进行并行计算。
4. Tuple(元组)在Storm中,数据以Tuple的形式在组件之间传递。
Tuple是一个数据结构,可以包含多个字段。
每个Tuple都有一个唯一的ID和标识符,用于在拓扑中进行传递和追踪。
5. Stream(数据流)Stream是由一系列Tuple组成的序列。
在拓扑中,数据流用于将数据在组件之间传递。

Note: Water weighs 8.33 pounds per gallon.o Avoid installation in an area where water could potentially freeze.o The water must be maintained at a level within the boundaries of the orange tape that surrounds the tank.o Petroleum products will damage the EPDM liner.o Temperatures above 180 Degrees Fahrenheit may damage the tank liner.o Check your water pH before filling the storage tank.▪For copper heat exchangers, the pH of the water must be maintained at between8.2 and 8.6.▪For stainless steel heat exchangers, the pH of the water should be maintained between 7 and 9.▪If you have a water supply with a pH lower than this, you must raise the pH to an acceptable level. You can do this with pH plus for pools.o Water with dissolved ions can act as an electrolyte causing electrolysis and resultant corrosion of copper pipes. Copper heat exchangers should be properly grounded for protection.o Installing a sacrificial anode rod similar to those used in hot water heaters can add another level of protection if your water has dissolved ions.o Surface or well water not coming from a municipal system should be tested for substances corrosive to copper such as cyanides and ferric, cupric, and ammonium salts. A different water source should be used if any of these substances are present. o The warranty does not cover any on-site installation accidents or occurrences, including but not limited to: the liner being damaged during set-up, the aluminum outer skin of the tank being dropped onto the liner, the liner ripping while forcing the tank through a tight opening or while positioning the heat exchange coils on the tank bottom without properly lifting the coils into place.Applications•The SunMaxx StorMaxx non-pressurized water tank is used where a buffer tank is necessary to eliminate cycling and storage of thermal energyproduced during day time hours, while still keeping sufficient watertemperature for night time hours.Uses Includeo Warm Water Baseboarding.

Maneuver the shell with insulationseparately. Keep the bubble wrap on while maneuvering. If you are going to move the tank down stairs, tape cardboard to the bottom of the tank for protection.Uncrating the Tank1.Remove the stretch wrap from the crate.2.Remove the top and vertical crate supports.3.Remove the aluminum lid cover located on the outside of the tank.4.Remove the pieces that can easily be reached from inside the tank liner.5.Leave the bubble wrap on. Lay the tank down on its side. Remove thecrate bottom.6.With the tank is on its side, push the liner inside the tank. This protectsthe liner while moving the tank into position.7.Clean the floor at the desired tank location.8.Make sure the floor is level. Note: If the floor is not level, the tank willnot be round at the top and the lid will not fit properly. If this is the case, shim the low spots on the aluminum tank shell. The shims can later be removed once the tank is full and the lid is in place.9.Move the tank to the desired location. NOTE: Do not drag the liner or laythe shell on the liner while maneuvering the tank.Assembly of the Tank1.Open the tank out into a circle. Measure to ensure a circular shape.y the tank bottom on the ground with the with the blue Styrofoam sidefacing down.3.Lift one side of the tank and slide the bottom under the tank. Note: Makesure the tank’s liner does not get caught between the tank’s wall andbottom.4.Fit the tank shell around the bottom, making sure the shell insulation fallsaround the edges. It will be a tight fit. Work your way around the shell pulling out and pushing down. Note: It may be necessary to get inside the tank, pushing out on the shell to accomplish this.5.Climb inside the tank. Be careful not to damage the liner. Straighten outthe pleats of the rubber liner.Installing the Tank Heat Exchanger(s)Notes:•Dripping solder will not damage the tank EPDM.•Hot supply or return lines are plumbed to the tops of coils. Cold supply or return lines are plumbed to the bottoms.•Coils should be placed so they can be easily plumbed to the tank pass-throughs.•Multiple coils must be plumbed together in parallel, not series. Position the coils to optimize this plumbing. The diagram below shows coils piped in parallel.•Hot water supply pipes from the tank should be plumbed with a mixing or anti-scald valve.• If using heat transfer fluid like propylene glycol, there must be two isolated coils, one for the heat transfer fluid, and one for domestic water.•Bullhead tees reduce head pressure and increase flow rates. Bullhead tees are required for any application with over 50,000BTUs of heat loss.1.Inspect the coil(s) for any shipping damage.2.Lower the coil(s) into the tank, gently setting the base blocks onto theliner.3.Plumb the coils according to the individual job piping scheme.4.Seal all pipe pass-throughs with high temperature silicone sealer. Besure to clean all copper pipe in the pass-throughs beforehand to ensurea good bond with the silicone sealer.5.Pressure check all solder joints before putting water in the tank.6.Ground the pipes (copper only).Lid Support Design1)Design of the lid support is two ways:a)Metal brackets around perimeter, spaced such that the spacing, B,is no more than 25”b)Copper vertical supports are added for diameter above 64” toincrease lid support2)Testing of the lid support was done on a 64” tank with metal bracketsonly, to simulate the span of the worst case scenario which has anunsupported span of 60”a)Test locations are marked with an “x”, located designated weakpoints.b)Testing of lid support completed by 3rd party. Lid did not fail inany of these tests.Installing The Copper Lid Supports (64 in diameter and larger)1)Copper lid support is built from ¾” copper pipe, cross, end cap, andtee as shown above.2)Pick out the lid support center post. The photos above show the topand bottom of the center post.3)There are four 1” pass-throughs positioned at right angles around theperimeter of the tank. Find them.4)Fully insert the copper lid supports into the cross fitting at the top ofthe center post and into the pass-throughs in the tank shell.5)The tank shell is flexible. Pull each lid support out of its pass-throughand assemble the nut, pass through and cap on the pipe.6)Slide each pipe back into its pass-through and loosely tighten the nut.7)Each branch of the cross should be equal in length and the tank shouldbe circular. Measure to ensure this is true.8)Hand tighten each of the nuts to secure the support. DO NOT use awrench.9)Apply a thick seam of silicone to seal the gap between the liner andnut. This ensures that water condensing on the pipe above the waterline will not leak into the insulation or down the outside of the tank.Copper pipe lid support for tanks with diameter larger than 128”•For tanks with diameter 64” through 128”, 1 copper cross is sufficient to support the lid with metal brackets (see next section).•For tanks above 128” in diameter, additional copper support is needed. Four copper crosses are used to ensure sufficient support to tank lid.•Use ¾” copper, copper cross, copper cap, and copper tees for copper lid support, similar to previous section.Tank supportInstalling metal brackets for lid support•Metal supports are made of 0.024” thick 316 stainless steel. It shall be bent to the dimensions shown below of 3”x2”x2”x2”. It shall be 2” in width.•Spacing of metal supports should be a maximum of 25”. The number of brackets required is dependent on the tank size.•For tanks with copper support, position of the copper support can take the place of a needed metal bracket.Fill port installation• Fill port must be installed 12” from outer edge of tank • Allows for easy access to fill the tank• Drill 7/16” hole in top of cap to ensure no pressure buildupOptional Add-on: Sacrificial Anode Rod• Anode rod can be installed 12” from outer edge of tank (opposite side of tank lid from fill port) Fill the Heat Storage Tank with Water• Piping should have already been pressure checked at this point.• Water chemistry questions should have already been addressed at this point.1. Fill the tank with cold water up to the BOTTOM OF THE ORANGE TAPE. DO NOT OVERFILL.2. Test the pH of the water.a. pH for Copper heat exchangers: 8.2-8.6.b. pH for Stainless steel heat exchangers: 7-10.c. Use pH plus for pools to raise the pH if necessary.Lid Support Pass-Through Exploded View• CPVC Cap• Lock nut• CPVC pass through• Inner Tank Wall• Lock NutPlacing the Lid on the Tank1.Do not try to insert the lid yet. Place it on top of the tank, liner facingdown. The overcut edge of the liner should come up over the shell.2.Push the lid down 1” evenly across the entire tank, making sure theovercut lid liner ends up between the lid and shell liner.3.Apply silicone to the seam where the lid liner and tank liners meet.4.Push the lid all the way in until it rests on the brackets or lid supports.5.Apply more silicone to the liner seam. This will prevent condensationfrom forming under the lid cover.Placing the Aluminum Lid Cover and Trim1.If the lid cover has come in 2 pieces, use the rivets provided to put thepieces together. Rivets should be spaced every 6”-8” along seam.2.The lid comes with vent cap installed. Unscrew the vent cap and set itaside.3.Place the lid cover on the tank, fitting the precut hole over the CPVCport nipple and lining up the edge of the lid cover with the shell.4.Apply Teflon tape to the threads of the PVC nipple. This will preventwater condensing on the inside of the cap from running down into thelid insulation.5.Screw the vent cap back on.6.Position the crimped aluminum trim pieces around the outside of thelid cover and tank shell, covering the entire perimeter seam.7.Secure the trim to the lid cover with the self-tapping screws provided.There should be 15 screws per 48” of edge cap spaced every 6” on lidtop a nd every 12” around side of tank. Trim material is made from0.02” 3003 Aluminum.Owner Maintenance ChecklistCAUTION: BE CAREFUL WHEN REMOVING THE PVC CAP AS WATER CAN BE VERY HOT.1.Check for leaks on a regular basis. Contact the installer if a leak isdetected.2.Once a year, check the tank’s water level. Remove the white cap fromthe access port and use a long wood dowel to check the water level. Thewater level should be within the orange tape around the tank. Whendetermining the water level, remember the tank bottom insulation is 2”thick. Water can be added through the access port. Remove the oldTeflon tape and put new tape on the threads each time the cap isremoved.3.Check the pH level to ensure it is within the desired range.4.Check that the tank temperature does not exceed 180°F. Installer shall setcontroller settings to ensure temperature requirements are met.5.Check circuit breaker which supplies power to controller which controlstank temperature.6.When used for space heating, check circulator pumps at the start ofheating season.7.When used for warm air delivery system, check air filter and replace asneeded.8.Check silicone seals of all passages.Tank Labels Tank warning labelsTank Label DetailsFill Line LabelHeat Exchanger Pipe Labels。

Storm应用场景详解
Storm应用场景详解Storm是一个分布式的、可靠的、容错的数据流处理系统(流式计算框架,可以和mapreduce的离线计算框架对比理解)。
整个任务被委派给不同的组件,每个组件负责一个简单的特定的处理任务。
Storm集群的输入流是一个叫spout的组件负责接入处理。
spout把数据传给bolt组件,bolt组件可以对数据完成某种转化。
bolt组件可以把数据持久化,或者传送到其他的bolt。
可以把Storm集群想象成一个bolt组件链,每个组件负责对spout流入的数据(也可以是其他bolt流入的数据)进行某种形式的处理。
有个简单的例子可以说明这个概念。
昨晚我看新闻,节目中发言人在谈论政治家以及他们在不用领域的立场。
他们不停地在重复一些不同的名字,这时我想知道他们提到的每个名字出现的次数是否一样,还是在某些名字被提及次数更多。
把发言人的言语想象成数据的输入流。
我们可以定义一个spout 从文件(通过socket、HTTP或者其他方式)读取这些输入。
当几行文本到来时,spout把它们传送给bolt,bolt负责把文本分词。
接着数据流被传送到另外一个bolt,这个bolt负责在一个已经定义好的政治家名单进行比对。
如果匹配到了,将数据库中对应的名字的计数加1。
任何时候你想看结果,只要从数据库中查询就可以,因为当数据到达时整个过程都是实时更新的。
这过程中所有的组件(spout和bolt)以及他们之间的连接被称为拓扑(topology)(见图表 1-1)。
现在很容易想象定义每个bolt和spout并行度,这样可以无限地扩展整个拓扑。
很神奇,对吧?尽管前面讲的只是一个简单的例子,不过你大概已经隐约感觉到Storm的强大了。
那么,Storm适用什么应用场景呢?•数据流处理:正如上述的例子,Storm不像其他流处理系统,因为Storm不需要中间队列。
•持续计算:持续地向客户端发送数据,它们可以实时的更新以及展现数据,比如网站指标。
