we have a large cluster (50TB) that doesn't require near realtime search accuracy, and we want to boost up our indexing performance there, so we thought we should increase the refresh_interval for our indices.
We wanted to know if it has any flaws we should consider, for example: (let's say we set it to 15m)
- we happens if a node fails ? will we have a data loss?
- what happens when all indices actually refresh ? will we have a huge load at that time?
