Recently the company cloud host can apply for the use of, engaged in a few machines to get a small cluster, easy to debug the various components currently used. This series is just a personal memo to use, how convenient how to come, and not necessarily the normal OPS operation method. At the same time, because the focus point is limited (currently mainly spark, Storm), and will not be the current CDH of the various components are complete, just accor

Redis Shards:Why shards: As Redis stores more and more data, the performance of Redis is getting worse!Current methods of sharding:1. Client ShardAt the application level of sharding, the program specifies what data is stored in the Redis advantage: more flexible disadvantage: Add a node expansion is very laborious 2, Agent Proxy shard Third party twemproxy use agent shortcomings, you agent what performance, then your whole redis performance is what kind of! 3. Redis cluster4, Codis (pea pod) Op

Hadoop is a complex system mix and it's a hassle to build a Hadoop environment for production.

This article will be through two computers Here's a quick introduction to how the Windows platform builds MySQL clusters. MySQL cluster supports multiple computers, the MySQL cluster built in this article for example, two, one (IP for 192.168.24.33) deployment Management node, data node and SQL node, and another (IP for 192.168.24.82) deployment data node and SQL node.In practice, do not deploy the manageme

The previous article explains the process of building the Redis cluster based on Redis cluster, and continues to explain the increase and decrease of node in the Redis cluster below. adding nodes in a cluster Let's test again, add a new node, in 2 cases, 1 as the primary node, 2 as a node from the node. Let's try this

WAS cluster series (12): Build a cluster: Step 10: view the was cluster mechanism through the verification program. To better understand the working mechanism of the was cluster, let's refresh the test program several times on a node and pay attention to the following parameters: "Local address" and "Local port", for e

The network traffic of full node replication from single machine to cluster session management mode one is increasing with the increase of the number of nodes, and it is precisely because of this factor that it is impossible to build larger clusters, in order to make the cluster nodes more larger, The first solution is the data replication traffic growth problem, the following will describe another way of

Label:The extract part is shown here, as below, What's the difference in using Clustervs using replication? In a replication system, one MySQL master server updates one or more slave servers. The transactions are committed sequentially, so a slow transaction can cause the server to lag behind the primary server for a period of time. This also means that if the primary server fails, Then from the server may be missing the last small portion of the transaction log. If you are using a transactional
