Re: zabbix on postgresql - very slow delete of events

Thanks Kenneth. In fact we've already partitioned the largest history* and trends* tables
and that has been running fine for a year. Performance was vastly improved. But since you
can't have a unique index on a partitioned table in postgres 10, we haven't worked on that.

Regards
Kristian

Hi Kristian,

Time series databases like Zabbix work poorly with the Housekeeper
service. We had many similar sorts of problems as our Zabbix usage
grew. Once we partitioned the big tables, turned off the Housekeeper,
and cleaned up by dropping partitions instead everything worked much,
much, much better. When we started using partitioning, we used the
old inheiritance style. Now you can use the native partitioning.

Regards,
Ken
