Vladislav Pyatkov updated IGNITE-19889:
---------------------------------------
Description:
*Motivation*
Client timestamp is used to determine a read timestamp for RO transaction on
client-side (IGNITE-19888). For consistency behavior, need to implement a
similar timestamp on server.
*Implementation note*
The last server observable timestamp should update at least when the
transaction commuted.
Any RO transaction should use the timestamp: for SQL (IGNITE-19898) and through
key-value API (IGNITE-19887)
Definition of done:
All serve-side created RO transaction should execute in past with timestamp has
been determining by last observation time.
was:
*Motivation*
Client timestamp is used to determine read timestamp for RO transaction.
Currently, this timestamp never update, that lead to violation guaranties of
linearization on client.
*Implementation note*
For commit RW transaction, use a method which return commit timestamp (the
method is implemented in IGNITE-19886)
Propagate commit timestamp from server to client on RW transaction commit and
update client timestamp
Propagate read timestamp from server to client (read timestamp for client RO
transaction is determined in IGNITE-19888)
