Client-side tuning for low latency systems

We have introduced several recipes to avoid server side blocking. Those recipes should help the cluster run stably and with high performance. Cluster throughput and average latency will be improved significantly by server-side tuning.

However, in low latency and real-time systems, just server-side tuning is not enough. Even if it only occurs slightly, long time pause is not acceptable in low latency systems.

There are client-side configurations we can tune to avoid long time pause. In this recipe, we will describe how to tune those configurations and how they work.

Getting ready

Log in to your HBase client node as the user who accesses HBase.

How to do it...

Follow these instructions to perform client side tuning for write-heavy clusters:

1. 1. Reduce the hbase.client.pause property value in the hbase-site.xml file:

   $ vi $HBASE_HOME/conf/hbase-site.xml
   <property>
   <name>hbase.client.pause</name>
   <value>20</value>
   </property...
