Alexander Lapin updated IGNITE-19900:
-------------------------------------
Description:
h3. Motivation
RW tx protocol requires commit timestamp to be greater than all other
timestamps assosiated with previous tx actions of the same transacions. For
more details prease check
[IEP-91:Hybridlogicaltime|[https://cwiki.apache.org/confluence/display/IGNITE/IEP-91%3A+Transaction+protocol#IEP91:Transactionprotocol-Hybridlogicaltime].]
Thus any tx request/response up to the commit timestamp generation transfers
hybrid timestamp from one tx actor to another, where another actor adjust its
HLC as
{code:java}
max(requestTime.longValue() + 1, max(now, oldLatestTime + 1));{code}
See org.apache.ignite.internal.replicator.message.TimestampAware and
{code:java}
org.apache.ignite.internal.hlc.HybridClockImpl#update{code}
for more details
> Server nodes should both propagate and handle HLC timestamps to/from clients
> within tx RW protocol
