Summary: .NET: Thin 3.0: Track observable timestamp
Key: IGNITE-20056
URL: https://issues.apache.org/jira/browse/IGNITE-20056
Project: Ignite
Issue Type: Improvement
Components: platforms
Reporter: Vladislav Pyatkov
Assignee: Pavel Tupitsyn
*Motivation*
The read timestamp for a RO transaction is supposed to be determined by a
client timestamp to linearize transactions.
*Implementation notes*
* The response, which start RO transaction (IGNITE-19887) has to provide a
timestamp.
* Responses, which start SQL, also provide a specific timestamp (if they start
RO internally) (IGNITE-19898 here the concrete method to retrieve timestamp
will be implemented).
* The current server timestamp ({{clock.now()}}) should be added to (except in
the cases above) the transaction response.
* 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.
