Vladislav Pyatkov updated IGNITE-19898:
---------------------------------------
Description:
*Motivation*
Reorganization of processing of RO transaction requires choosing a specific
timestamp for an implicit RO SQL transaction.
*Implementation notes*
Observation timestamp is passed through API and propagate to SQL engine
If SQL script does not require starting an implicit RO transaction, the
timestamp is not used.
If the SQL is started an RO transaction, the transaction should be created
using the timestamp.
*Definition of done*
Select in an implicit transaction should execute with an observation timestamp.
> SQL implicit RO transaction should used observation timestamp
