Created table t1 on clustrix.
MySQL [test]> show create table t1\G

*************************** 1. row ***************************

Table: t1
|
Create Table: CREATE TABLE `t1` (
|
`col1` int(11),
|
`col2` int(11)
|
) CHARACTER SET utf8 /*$ SLICES=3 */
|
Start maxscale:
maxscale -d -f /etc/maxscale_trxreplay.cnf --user=root
Using maxctrl set master and slave servers
[root@karma197 bin]# maxctrl set server MBS Master; maxctrl set server MBS2 Slave
Used inserter to write data in a table.
python inserter.py -n 50000000 -h karma197 -P 4008 -u maxscale -pmaxscale_pw -D test -t 50 t1
This tries to insert 50000000 rows in table t1 with 50 threads.
It inserts a few rows in the target table and fatals.
[root@karma197 bin]# maxscale -d -f /etc/maxscale_trxreplay.cnf --user=root
