Roman Puchkovskiy updated IGNITE-19226:
---------------------------------------
Description:
Currently, when obtaining a schema, its latest (from the local point of view)
version is returned.
# Table schema must always be obtained using a timestamp
# This might require a wait (until MetaStorage's SafeTime >= schemaTs-DD, see
[https://cwiki.apache.org/confluence/display/IGNITE/IEP-98%3A+Schema+Synchronization#IEP98:SchemaSynchronization-Waitingforsafetimeinthepast]
)
This includes the mechanisms that allow clients obtain 'current' schema (like
'DESCRIBE <table>', 'list tables', etc).
