Vladislav Pyatkov updated IGNITE-19888:
---------------------------------------
Description:
*Motivation*
Read timestamp for RO transaction is supposed to determine with taking into
client timestamp to linearize client transactions.
*Implementation notes*
Responses, which start RO transaction (IGNITE-19887) and commit RW transaction
(IGNITE-19886), have to provide a timestamp.
If a server response does not have the timestamp or timestamp is less than the
client already has, do nothing.
If the time is grater than the client has, the client timestamp should be
updated.
The timestamp is used to start RO transaction (IGNITE-19887)
*Definition of done*
The timestamp is passed from the server-side to a client. The client just save
the timestamp and send it in each request to server-side.
All client-side created RO transactions should execute in past with timestamp
has been determining by client timestamp.
