在一个需要低延时响应的hbase集群中,使用hbase默认的客户端超时配置简直就是灾难. 但是我们可以考虑在客户端上加上如下几个参数,去改变这种状况: 1. hbase.rpc.timeout: RPC timeout, The default 60s, 可以修改为5000(5s) 2. ipc.socket.timeout: Socket link timeout, should be less than or equal to RPC timeout, the default is 20s
hbase读数据用scan,读数据加速的配置参数为: Scan scan = new Scan(); scan.setCaching(500); // 1 is the default in Scan, which will be bad for MapReduce jobs scan.setCacheBlocks(false); // don't set to true for MR jobs 其中, public Scan setCacheBlocks(boolean cacheBlocks
MySQL 各种超时参数的含义 今日在查看锁超时的设置时,看到show variables like '%timeout%';语句输出结果中的十几种超时参数时突然想整理一下,不知道大家有没有想过,这么多的timeout参数,到底有什么区别,都是做什么用的呢? MySQL [(none)]> show variables like '%timeout%'; +------------------------------+----------+ | Variable_name | Value | +
