Andrey Mashenkov updated IGNITE-19081:
--------------------------------------
Description:
Catalog service should trigger events when it's state was changed.
Other components should be able to subscribe on these events.
Example:
{code:java}
CreateTableEvent = {TableDescriptor} // Contains tableId and parameter from
CREATE TABLE command.
AddColumnEvent = {tableId, ColumnDescriptor}
{code}
Maybe some additional info will be required, e.g. for finishing future if DDL
operation was triggered locally.
Note: Let's make these changes aside and avoid breaking the current
implementation.
was:
Let's
* implement CatalogManager methods that will validate and save catalog changes
to the MetaStorage.
* implement Metastorage WatchListener that will apply these changes and update
CatalogService state.
> Introduce Catalog events and subscribe other components.
