------------------------------------------
Summary: Do not increment hybrid clock timestamp in RO transaction
Key: IGNITE-23323
URL: https://issues.apache.org/jira/browse/IGNITE-23323
Project: Ignite
Issue Type: Improvement
Reporter: Vladislav Pyatkov
h3. Motivation
Hybrid clock is incremented in any time when we are getting a current
timestamp. We can avoid increments, reduce latency in the case of RO
transactions, and replace the cas operation with the only volatile read.
{code}
@Override
public long nonUniqNow() {
return latestTime;
}
@Override
public HybridTimestamp nonUniqTimestampNow() {
return hybridTimestamp(latestTime);
}
{code}
