Do not write history/state/overdue when not reponsible #85

Closed N-o-X closed 3 years ago

N-o-X commented 4 years ago

Concept:

Only the active Icinga DB writes into MySQL
The active instance also writes the last Redis stream ID into something like a history_state table
The inactive instance removes everything before the stream ID plus a time buffer from its own stream (using https://redis.io/commands/xrange)

@N-o-X Curious on this, is this to a fix an issue where the inactive icingadb instance is marking checks as overdue when they infact are not overdue? Currently running into an issue with this, wondering if that's what this is intended for or if I should create a different issue. Thanks!

Hi @stupiddr,

this issues didn't have such a bug in mind, it's just here to lower the amount of writes to MySQL. Your problem is indeed new to me. It would be great, if you could create a new issues on that topic.

Thanks and greetings Noah
