Amit Patel updated HBASE-18643:
-------------------------------
Description:
In [HBASE-14070|https://issues.apache.org/jira/browse/HBASE-14070] and
[HBASE-18642|https://issues.apache.org/jira/browse/HBASE-18642], we discuss
using HLC and deprecating the client from being able to set timestamps for
mutations. However, one important use case for setting the timestamps (which
represent transaction IDs) is for transactions. What we could do is add a
transaction ID to the result object that is the hybrid logical timestamp of a
particular batch operation.
The transaction ID should be considered opaque and clients should not make
assumptions for how the ID is changed.
