Mirza Aliev updated IGNITE-17515:
---------------------------------
Description:
Currently, {{tablesByIdVv}}, which holds the mapping for table ids and table
implementations, is updated through the mechanism of versioned values, and
{{tablesByIdVv}} is dependent on a list of other versioned values, like schema
versioned value, calcite versioned value and etc. If one of this versioned
value is completed exceptionally, {{tablesByIdVv}} will also be completed
exceptionally, and that means that we cannot access to the the mapping for
table ids and tables, and actually that means, that all tables will be
unreachable.
Also, that means, that tables can't be properly stopped, which can lead to
resource leaking.
Expected behaviour is when exceptional situations for {{tablesByIdVv}} updates
are handled, tables, that weren't participated in the updated, still
accessible, and tables, that were affected, properly stopped.
