> We've got a lot of write timeouts (cas) when running
> "INSERT INTO cas_demo(pri_id, sec_id, flag, something) VALUES(?, ?, ?, ?) IF
> NOT EXISTS"
> from 16 connections in parallel using the same pri_id and different sec_id.
> Doing the same from 4 connections in parallel works ok.
> All configuration values are at their default values.
> CREATE TABLE cas_demo (
> pri_id varchar,
> sec_id varchar,
> flag boolean,
> something set<varchar>,
> PRIMARY KEY (pri_id, sec_id)
> );
> CREATE INDEX cas_demo_flag ON cas_demo(flag);
> Full thread dump is attached.
