@InterfaceAudience.LimitedPrivate(value="Replication")
@Deprecated
public class HLogKey
extends WALKey
implements org.apache.hadoop.io.Writable

A Key for an entry in the change log. The log intermingles edits to many tables and rows, so each log entry identifies the appropriate table and row. Within a table and row, they're also sorted.

Some Transactional edits (START, COMMIT, ABORT) will not have an associated row.

Create the log key for writing to somewhere. We maintain the tablename mainly for debugging purposes. A regionName is always a sub-table object.

Used by log splitting and snapshots.

参数:

encodedRegionName - Encoded name of the region as returned by HRegionInfo#getEncodedNameAsBytes().

tablename - - name of table

logSeqNum - - log sequence number

now - Time at which this edit was written.

clusterIds - the clusters that have consumed the change(used in Replication)
