Iurii Gerzhedovich commented on IGNITE-24053:
---------------------------------------------
The proposal is to have a single time tracker in the JDBC driver. JDBC driver
is singleton inside of JVM, so we will have the same visibility guarantee for
any JDBC connection even user uses a connection pool. The guarantee will not
depend on how many different nodes are used for connection in the connection
pool.
> Attach observation timestamp for JDBC client requests

> Issue Type: Improvement

> h3. Motivation
> Among the JDBC requests, we can have read requests that required an
> observation timestamp to calculate the read timestamp correctly.
> It is already done for SQL requests ({{ClientSqlExecuteRequest,
> ClientSqlExecuteBatchRequest, ClientSqlExecuteScriptRequest}}) and have to
> do the same for the JDBC.
> h3. Definition of done
> * JdbcQueryEventHandlerImpl#timestampTracker oughе to disappear
> * The observation timestamp should be tracked only on the client side
> (dedicated for any client)
