Description

Sometime it is useful to force a query to executed serially.

For example a user might want to run a query which is not latency sensitive to him/her. In that case providing the SERIAL hint puts less load on the HBase cluster and impact other more latency sensitive queries less.

(In my case I want to use this for testing.)
