Now watch has integrated the livereload, so put them together to illustrate.Watch can monitor specific files, automate custom tasks such as Livereload, and so on when adding files, modifying files, or deleting files.1. InstallationProject definition on GitHub, address: Https://github.com/gruntjs/grunt-contrib-watchCan be installed directly via NPMInstall Grunt-contrib-watch--save-devAfter installation, you need to add a registration for the task in Gruntfile.js.Grunt.loadnpmtasks (' Grunt-contri

, update the FILE_BATCH_NO state of the main library for success.In these four processes, three timers are required. There are two timers that guarantee data consistency between the main library and the Sub Library, and another timer is responsible for asynchronously updating the consistency of the main library batch and sub-batches.For a third scenario, you can extract common logic to solve similar scenarios. For example, according to the conditions, delete the various sub-libraries to meet the

pre-existing and the client creates a temporary ordered node under it (this can be specified by the node's property control: createmode.ephemeral_sequential). ZK's parent node (/distribute_lock) maintains a copy of the sequence, guaranteeing the temporal timing of the creation of the child nodes, thus forming the global timing for each client. 4. Distributed queuesThere are two simple, one is the regular FIFO queue, the other is to wait until the queue member NAND after the unified sequent

1, the purpose is to improve efficiency. To put it simply, distributed is to improve efficiency by shortening the execution time of a single task , while clustering increases efficiency by increasing the number of tasks executed per unit of time . For example, if a task consists of 10 subtasks, each of which takes 1 hours to execute independently, it takes 10 hours to perform a change task on a single server.The distributed scheme provides 10 servers,

Let's talk about the situation first. The framework uses Laravel, the task queue is BEANSTALKD, and then php artisan queue:listen Now I have a reptile task that needs to be run once in a while, and the crawler will add some subtasks to the task queue during the crawl. The next crawler task needs to wait until all the previous crawlers have completed their tasks before they can begin. However, the crawler's time is unknown, and no method is found

Label: I/O using sp data div problem bs adDatabase query:Database queries have a great impact on both concurrent processing and transaction processing;The better the query performance, the less impact the performance will be caused by the increase in concurrency;The better the query performance, the less affected by the exclusive lock of other transactions;In short, it is the most fundamental way to solve timeout and deadlock issues, optimize query performance, and shorten the transaction time (

Contentengine provides a framework that enables system event or custom event to execute user-specified action when the object or class in Content Engine is triggered ). We call it subtasks. That is to say, subtasks bind the event action, one or more events with the target Content Engine object or class that listens to the event. Generally, eventaction is implemented by the developer code, while subscribe is

Once I saw a group of friends discussing this difference in the group and reading their comments, I thought it was very reasonable and easy to understand. It was recorded here as a learning note: Use two examples to see the differences between distributed and cluster: Example 1: If a task is composed of 10 subtasks, it takes one hour for each subtask to be executed separately, it takes 10 hours for the task to be executed on a server.The Distributed

1 fp-tree parallel algorithm in the cluster system (many for one task or is it a cloud computing single for many multiple tasks?) ）The computer cluster system uses the network to connect a group of workstations or PCs with high performance to a certain structure, thus forming an efficient parallel computing process.System. Communication is implemented between nodes using messaging, and cluster systems are often used to improve the computational speed and reliability of a single computer.The proc

Topics [topic] |! Topics [topic]. queue. length) return; // trigger an event by looping the topics queue! Var items = topics [topic]. queue; items. forEach (function (item) {ite

follows: Worker: Rose programmer 2 is begin. worker: Json Programmer 3 is begin. worker: Jack Programmer 1 is begin. worker: Jack Programmer 1 is end. worker: Json Programmer 3 is end. worker: Rose programmer 2 is end. main thread end! As can be seen from the results, the MainThread will be blocked in latch. await (); until all three threads are completed, the MainThread will continue to execute (4) References This section briefly describes how to use CountDownLatch. For more information, see

interface is Callable and declared: public interface Callable To indicate the asynchronous call result, we define an interface MyFuture, as shown below: public interface MyFuture The get method of this interface returns the real result. If the result has not been computed, the get method will be blocked until the calculation is complete. If an exception occurs during the call, the get method throws an exception during the call. To facilitate the main thread to call

, such as word, which can be typed, spell-checked, and printed at the same time. Within a process, to do multiple tasks at the same time, you need to run multiple "subtasks" at the same time, and we refer to these "subtasks" in the process as threads (thread).Because each process has at least one thing to do, a process has at least a single thread. Of course, a complex process such as word can have multiple

automatically adapt to the new situation. This provides the highest degree of flexibility for parallelizing any kind of operations: (1) Before the statement is executed, the physical data subsets accessed in parallel are dynamically optimized for each query requirement. (2) The degree of parallelism is optimized for each query. Unlike the non-shared environment, there is no required minimum degree of parallelism to call all nodes to access all data, which is the basic requirement for accessing

execution, get return result:1. Create future taskfuturetaskMaster-worker modeImplemented by two types of threads: the master thread is responsible for receiving and distributing tasks (splitting tasks into subtasks), the worker thread is responsible for processing subtasks, each worker thread handles only a subset of tasks, and all worker threads work together to handle all tasks.The advantage is the abil

parallel multitasking can only be done on multicore CPUs, but because the number of tasks is much larger than the number of cores in the CPU, the operating system automatically shifts many tasks to each core.For the operating system, a task is a process, such as open a browser is to start a browser process, open a notepad started a Notepad process, open two Notepad started the two Notepad process, open a word started a word process.Some processes do more than one thing at the same time, such as

. ProcessFuturer (result. get ()); } 17. fork-join framework (large tasks are divided into small tasks and merge is executed in parallel) RecursiveTask is used to return computing results, while RecursiveAction is used to return non-computing results. The compute between the two is used to generate and call subtasks and merge the results.
