As Ted said, readpoint is not changed. The readpoint which is being used for the rollback is not committed yet, so none of the scanner is reading it at this point. For the snapshots, the patch needs to be altered a bit. Basically, if the kv is present in snapshot then it will not be in memstore kv, and vice versa. So, while deleting the new kv, if it is deleted from snapshot, then the old kv should be only added to the snapshot. Similarly, if the new kv is deleted from memstore's kv, then the old kv should be added to the memstore's kv. I'll upload a revised patch. > Append, Increment: Adding rollback support > -- > > Key: HBASE-8028 > URL: https://issues.apache.org/jira/browse/HBASE-8028 > Project: HBase > Issue Type: Bug > Components: regionserver >Affects Versions: 0.94.5 >Reporter: Himanshu Vashishtha >Assignee: Himanshu Vashishtha > Fix For: 0.95.0 > > Attachments: HBase-8028-v1.patch, HBase-8028-v2.patch, > HBase-8028-with-Increments-v1.patch, HBase-8028-with-Increments-v2.patch > > > In case there is an exception while doing the log-sync, the memstore is not > rollbacked, while the mvcc is _always_ forwarded to the writeentry created at > the beginning of the operation.

bq. Will this change the readpoint?
{code}
private long internalAdd(final KeyValue toAdd) {
long s = heapSizeChange(toAdd, this.kvset.add(toAdd));
timeRangeTracker.includeTimestamp(toAdd);
this.size.addAndGet(s);
return s;
}
{code}
Looking at the code, I don't think readpoint is affected.
