Hi,
I have never used any 'hash index' but saw documents in the past suggesting
issues around hash index , like WAL doesnt generate for "hash index" which
means we can't get the hash index back after crash also they are not
applied to replicas etc. And also these indexes can not be used for range
queries , for sorting etc.
However, we are seeing that one of the databases has multiple hash indexes
created. So I wanted to understand from experts here, if it's advisable in
any specific scenarios over B-tre despite such downsides?
Note- Its version 15.4 database.
