Aleksandr Polovtcev updated IGNITE-18732:
-----------------------------------------
Description:
{{SchemaManager}} class has two methods, that perform a blocking {{get}} call
on a {{CompletableFuture}}: {{latestSchemaVersion}} and {{schemaByVersion}}.
Instead, these methods should return the future and its callers must be
rewritten in an asynchronous style.
UPD: When removing blocking calls in SchemaManager, it was discovered, that
{{fireEvent}} was called from the async part of the configuration listener.
This is a problem, because {{fireEvent}} listeners call
{{VersionedValue#update}} which can already be notified of the new
configuration revision, in which case update will throw an exception.
