I have face a issue with indices rollover automation with ILM. Created ILM policy with rollover Max index size is 1GB. But rollover is happening at 1.2 GB. almost 0.2 GB lag is there.
Also, changed the Cluster ILM poll interval to 1s.
Any indices performance issue will be face by setting ILM poll interval to "1s" ?
How to reduce 0.2 gb lab on rollover condition ?
