Hey all,
We’re looking at setting up snapshot policies for our indexes, and wanted to understand how the underlying data is handled when we’re doing periodic rollovers.
I understand that snapshots are incremental, so if we expand an index, a subsequent snapshot will only included the changes since.
However, if we are rolling over the index, and a snapshot happens before and after rollover, how is that handled? Does the same underlying data get duplicated because those are two distinct indexes? We change the number of shards / replications, and move the shards during rollover.
Cheers!
