Kirill Tkalenko reassigned IGNITE-20886:
----------------------------------------
Assignee: Kirill Tkalenko
> Don't unregister indexes on CatalogEvent#INDEX_DROP
> ---------------------------------------------------
>
> Key: IGNITE-20886
> URL: https://issues.apache.org/jira/browse/IGNITE-20886
> Project: Ignite
> Issue Type: Improvement
> Reporter: Kirill Tkalenko
> Assignee: Kirill Tkalenko
> Priority: Major
> Labels: ignite-3
>
> At the moment, when performing an UpdateOperation, we use only those indexes
> that are current at the time of the operation, which is not correct.
> We must update all available indexes since the catalog version on which the
> transaction began, as well as all registered indexes since the beginning of
> the transaction that have not been deleted.
> In this ticket, we need not unregister indexes on
> *org.apache.ignite.internal.catalog.events.CatalogEvent#INDEX_DROP*
> (*org.apache.ignite.internal.index.IndexManager#onIndexDrop*), since they may
> be needed when performing the operations described above.
> Unregistration of indexes must occur in IGNITE-20121(or IGNITE-20120) before
> we realize that we no longer need the index and we can safely physically
> delete this index both from the catalog (from previous versions) and its
> storage.
