------------------------------------------
Assignee: Roman Puchkovskiy
> Treat a schema change in which an index appears and gets switched to BUILDING
> as incompatible
> ---------------------------------------------------------------------------------------------
>
> Key: IGNITE-22990
> URL: https://issues.apache.org/jira/browse/IGNITE-22990
> Project: Ignite
> Issue Type: Improvement
> Reporter: Roman Puchkovskiy
> Assignee: Roman Puchkovskiy
> Priority: Major
> Labels: ignite-3
>
> If
> * an operation (an RW read/write or a commit) concerns table T
> * index I did not exist in InitialSchema for the transaction
> * in the schema corresponding to the operation/commit index I on table T is
> at least in the BUILDING state
> then the schemas are not compatible.
> In other words, we should not allow to commit an RW transaction which started
> on a schema before an index was created in the Catalog, but which tries to
> commit on a schema where the index was seen to be built.
> This will make the mechanism introduced in IGNITE-21017 obsolete and it will
> need to be removed (that is, we will need to both remove counting tx
> operations in PartitionReplicaListener and remove the corresponding
> datastructure). The reason is that the mechanism from IGNITE-21017 is heavier.
