• Spring configuration for Index Creation and output of Indices text for DevOps purposes
• Maven and Gradle tasks to output the current list of indices and Redis Search command

Maybe there could be a mechanism for assigning an alias when index is created initially so that when changes are made to the schema, a new index is created with incremented version number, alias points to new index, old index is dropped? To the end user they only ever access through the alias.

Something like:

1. User creates initial index:
   FT.CREATE myindex_v1 ...
   FT.ALIASADD myindex myindex_v1
2. Any change is made to schema:
   FT.CREATE myindex_v2 ...
   FT.ALIASUPDATE myindex myindex_v2
   FT.DROPINDEX myindex_v1

End user only accesses index through alias, myindex. Would need to evaluate performance impact if lots of updates are being made in short amount of time

Could have performance impact if lots of changes are made close together

For this we should follow the same JSON schema format from RedisVL.
