Ted Yu commented on HBASE-21246: -------------------------------- bq. Why isn't this a WALProvider method? The start time of a WAL is known at the creation of the WAL. This attribute would not change even after edits are appended to the WAL. Therefore I think it belongs to the identity. bq. Seems unused. This would be used in the (Ankit's) upcoming patch for replication. The other comments are addressed by patch v3. > Introduce WALIdentity interface > ------------------------------- > > Key: HBASE-21246 > URL: https://issues.apache.org/jira/browse/HBASE-21246 > Project: HBase > Issue Type: Sub-task > Reporter: Ted Yu > Assignee: Ted Yu > Priority: Major > Attachments: 21246.003.patch, 21246.HBASE-20952.001.patch, > 21246.HBASE-20952.002.patch > > > We are introducing WALIdentity interface so that the WAL representation can > be decoupled from distributed filesystem. > The interface provides getName method whose return value can represent > filename in distributed filesystem environment or, the name of the stream > when the WAL is backed by log stream. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
