We are experiencing significant latency in the refresh operation. In some cases refresh takes up to one minute to complete.
Our index is about 150GB large and has 32 shards spread across 12 nodes.
The refresh interval is currently set to 15s.
- Would a lower refresh interval speed up refresh at the cost of lower indexing speed?
- Would more nodes help to increase refresh performance?
- Are there any other measures to be done for increasing refresh performance?
