Semyon Danilov updated IGNITE-19209:
------------------------------------
Description:
At the moment there is a CatalogService that manages SchemaDescriptors
(database schemas, not table schemas) and TableDescriptors. CREATE TABLE is
being handled by the CatalogService, however it seems like it doesn't actually
write the schema to the metastorage.
I believe that two things must be done in the scope of this ticket:
1. Actually write new schema to the metastorage.
2. Use node's HLC + DD (Delay Duration) which is described in the
https://cwiki.apache.org/confluence/display/IGNITE/IEP-98%3A+Schema+Synchronization
as the new schema's activation time.
