[jira] [Comment Edited] (CASSANDRA-16092) Add Index Group Interface for Storage Attached Index
[ https://issues.apache.org/jira/browse/CASSANDRA-16092?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17609595#comment-17609595 ]

bq. Should this ticket be resolved fixed then?
The changes in isolation have been co-authored and reviewed by 3 committers, all of whom have insight into how this interface is already in use outside OSS. If there are issues at this point, I think they would pop up in relation to integration that happens in another issue (i.e. one also under the general umbrella of CASSANDRA-16052), where we would have appropriate space to discuss and address. WDYT?
Indeed, we don't have much precedent for this kind of thing.

> [Index group|https://github.com/datastax/cassandra/blob/storage_attached_index/src/java/org/apache/cassandra/index/Index.java#L634] interface allows:
> * indexes on the same table to receive centralized lifecycle events called secondary index groups. Sharing of data between multiple column indexes on the same table allows SAI disk usage to realise significant space savings over other index implementations.
> * index-group to analyze user query and provide a query plan that leverages all available indexes within the group.
