Checkpoint the compressed HLog ------------------------------ Key: HBASE-5403 URL: https://issues.apache.org/jira/browse/HBASE-5403 Project: HBase Issue Type: Improvement Reporter: Liyin Tang Assignee: Liyin Tang
Let's assume that HBase replication can be based on replaying the HLog in the replica cluster. The replica process could be crash during the replay. Obviously, the replica process need a way to start from the lastest check point in the HLog, even the HLog is compressed. So the proposal is to write a series of checkpoints within the HLog. Each each checkpoint will have a header with some special sequence of bytes. And between each checkpoints, HLog should use new dictionaries to compress. -- This message is automatically generated by JIRA.
