Liyin Tang created HBASE-10343: ---------------------------------- Summary: Write the last sequence id into the HLog during the RegionOpen time Key: HBASE-10343 URL: https://issues.apache.org/jira/browse/HBASE-10343 Project: HBase Issue Type: Improvement Reporter: Liyin Tang
HLog based async replication has a challenging to guarantee the in-order delivery when the Region is moving from one HLog stream to another HLog stream. One approach is to keep the last_sequence_id in the new HLog stream when opening the Region. So the replication framework is able to catch upto the last_sequence_id from the previous HLog stream, before replicating any new transactions through the new HLog stream. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
