the next article. When Message Queuing is required When you need to use Message Queuing, you first need to consider its necessity. There are many scenarios where MQ can be used, and the most common ones are doing business decoupling/FINAL consistency/broadcast/fault peak flow control. Conversely, RPC appears more appropriate if strong consistency is required and the results of business logic are concerned. decoupling Decoupling is the most essential problem to be solved by Message Queuing. The

[route] on the Action, we can also use the controller, when [route] is used on the controller, it defines a default routing rule that will work on all actions under the controller, Unless the [route] attribute is also applied on an Action, the [route] on the Controller is overwritten. Note, however, that the [Route] applied to the Controller must be prefixed with {action}, otherwise it will be thrown "Routedata must contain an item named ' Action ' with a value of a non-empty string." Error The

(corresponding to the Peer in the P2P system) has a randomly assigned ID. When ing content to a node, use the keyword of the content and the node ID to perform consistent hash and obtain the key value. Consistent hash requires that the key value and node ID are in the same value range. The simplest key values and IDS can be one-dimensional, such as an integer set from 0000 to 9999. When the content is stored based on the key value, the content is stored on the node with the ID closest to the ke

pipe call it 下游 .Two water pipes are connected in a certain way, so that each event is generated upstream, the event can be received downstream. Note here and the official website of the event diagram is the reverse, here the order of events sent is first 1, after 2, after 3 such order, the order of events received is also first 1, after 2, after 3 order, I think this is more in line with the thinking of our ordinary people, simple and clear. Here u

ObjectiveEveryone loved the Backpressure coming.In this section we will study in the future Backpressure . I look forward to eating more melon masses have already sat, do not worry, we first to review the previous section Zip .BusinessIn the previous section we said that zip can be sent to a number of upstream events sent to the downstream, then you have not thought of a problem, if one of the 水管A sending event is particularly fast, and another 水管B se

: grouping According to the specified field, the value of the same field must be emitted to the same task. Partial Key Grouping: Similar to the fields Grouping, Group distribution according to a part of the specified field, it is well implemented load balance, sending a tuple to the corresponding task of the downstream bolt, especially in the case of data skew, using Partial Key grouping can better improve resource utilization All Grouping: The task o

sent. In this respect, Trident adds a parameter that restricts the minimum interval between batches and batches, but this directly results in data latency depending on the setting of this parameter (similar to spark streaming). Flink transaction: Unlike Trident, Flink master does not control when to send data, it only controls when the batch is divided. Master sends the barrier control flow, dividing the source data into batches, and source can send data at any time.Master uses the Barrier comm

1. Overwrite Test Result Analysis To fully and accurately analyze the coverage test results, it is necessary to ensure that some key upstream and downstream parameters can be accurately recorded during the test.TD-SCDMAFor system coverage testing, the main data that needs to be recorded in real time includes the following. 1) terminal side of the road test: the value of the received signal code domain power, Carrier Interference Ratio, UE transmit pow

One, Control FlowIn control flow, the task is the smallest unit, and the task is kept in sync by precedence constraint.1,control Flow cannot pass data between components to perform tasks serially or in parallel, acting as the dispatcher of a task.If precedence constraint is not set between two tasks, then these two tasks are executed concurrently. In the design package, maximizing the concurrency of the task, the ability to take full advantage of server resources, helps reduce ETL execution time

and the number of digits transmitted by the sub-carrier is not supported, the bitwise switching function can be used to exchange the bitwise transmitted by the sub-carrier to other sub-carriers, thus reducing the disconnection caused by changing the channel characteristics of twisted pair wires. The local ADSL board and the user's modem must support this function at the same time to take effect. We recommend that you disable this function in the ADSL template. We recommend that you enable this

In tdd lte, upper and lower lines are not necessarily symmetric. When the number of downstream sub-frames is higher than that of the upstream sub-frames, the harq of multiple downstream sub-frames is reported in one upstream sub-frame. The number of harq records reported in an uplink sub-frame depends on the configuration of the LTE uplink and downlink MIMO modes. Through upper layer configuration, lte tdd

Load Balancing Scenario1) Initial: Upstream agent through Round_robin selector, the event is sent to downstream Collecotor1, Collector22) Fault: Shut down the Collector1 process to simulate the failure, Agent1 because the configuration of Backoff, will Collecotor1 temporarily removed from the Send list, the event all sent to Collector23) Restore: Restart the Collector1 process, Collector1 after the maximum timeout, re-enter the sending list, then t

of the work itself is difficult to achieve the magnitude of the time to shorten.If the design is automatically converted into usable code in the research and development system, there is no doubt that the development of the traditional Web page will be greatly improved. While it may seem like the final direction of a dedicated tool, in today's real world it can be resisted by increasing the burden of a designer's use, so it may be more appropriate to make a transition by making a contract in th

Note, however, that the [Route] applied to the Controller must be prefixed with {action}, otherwise it will be thrown "Routedata must contain an item named ' Action ' with a value of a non-empty string." Error The [Route] applied on the action is not added, because {action} is the current action.[Routeprefix ("promotions")][Route ("{action=index}")]The default route is defined above, and the default value for {actio

that since the beginning of 2017 daily hundreds of thousands of orders, by the end of the year, one-day orders have exceeded 7 million, the system faces enormous challenges. The payment channel is increasing, the link is lengthened, and the system complexity increases correspondingly. From the original POS machine to the later two-dimensional code products, small white box, small black box, seconds to pay ... Product diversification, the positioning of the system is also changing in the moment.

1: What are the characteristics of TDD technology? L Time Division Duplex (TDD): distinguishes uplink and downlink based on different time slots P advantages N when the upstream and downstream services are asymmetrical, different quantities of time slots can be flexibly allocated to the upstream and downstream operations, resulting in high spectrum efficiency. N uplink and downlink use the same frequency ca
