------------------------------------------
Summary: Include table creation timestamp in baseTs calculation
for schema validation
Key: IGNITE-20107
URL: https://issues.apache.org/jira/browse/IGNITE-20107
Project: Ignite
Issue Type: Improvement
Reporter: Roman Puchkovskiy
Fix For: 3.0.0-beta2
baseTs is used when validating a schema (schema at commitTs or at operationTs
is validated to match/be compatible to the schema at baseTs).
The easiest way to calculate baseTs is to do baseTs=beginTs(tx). But to make a
created table immediately available for already running transactions (as per
https://cwiki.apache.org/confluence/display/IGNITE/IEP-110%3A+Schema+synchronization%3A+basic+schema+changes#IEP110:Schemasynchronization:basicschemachanges-Basicrequirements
), we can take baseTs=Max(beginTs(tx), creationTs(table)).
