Table history_sync and history_uint_sync is growing

[limo]

Hi to all,

we found problem that zabbix db (innodb) is growing. We found that table history_uint_sync has 12.7GB, history_sync has 5.2Gib. Any suggestions how to cleanup? Is there some config parameter how long data will stay in this tables? We cannot use global history cleaner because we need some special items history for 365 days.

What will happen if this tables are truncated?

Thank you,
Lukas

No suggestions at all? We use 1.6.7 and two nodes. Problem is that size of DB increases rapidly. t did not before. Maybe it is related to some 1.6.x upgrade? Please where to setup amount of data stored in this table? It seems that our nodes has problems with history sync.. But firewall is opened and only version of servers changed (now both 1.6.8).
