> Add causality token of the last update of catalog descriptors to
> CatalogObjectDescriptor
> ----------------------------------------------------------------------------------------
>
> Key: IGNITE-20519
> URL: https://issues.apache.org/jira/browse/IGNITE-20519
> Project: Ignite
> Issue Type: Bug
> Reporter: Mirza Aliev
> Assignee: Mirza Aliev
> Priority: Major
> Labels: ignite-3
>
> *Motivation*
> It could be useful to add causality token of the last update of
> {{CatalogObjectDescriptor}}. For example, this will help us to call
> {{DistributionZoneManager#dataNodes(long causalityToken, int zoneId)}} for
> the specified {{CatalogZoneDescriptor}}, so we could receive data nodes with
> accordance of correct version of filter from {{CatalogZoneDescriptor}}
> *Implementation notes*
> This could be done with the enriching {{UpdateEntry#applyUpdate(Catalog
> catalog)}} with {{causalityToken}}, so we could propagate {{causalityToken}}
> to all {{UpdateEntry}}, where we recreate {{CatalogObjectDescriptor}} and
> create new version of {{Catalog}}
