@Deprecated
@Private
final class ProcedureWALFormat
extends Object

Deprecated.

Since 2.3.0, will be removed in 4.0.0. Keep here only for rolling upgrading, now we use the new region based procedure store.

Helper class that contains the WAL serialization utils.

Method Details

load

public static void load(Iterator<ProcedureWALFile> logs,
 ProcedureStoreTracker tracker,
 ProcedureWALFormat.Loader loader)
                 throws IOException

Deprecated.

Load all the procedures in these ProcedureWALFiles, and rebuild the given tracker if needed, i.e, the tracker is a partial one.

The method in the give loader will be called at the end after we load all the procedures and construct the hierarchy.

And we will call the ProcedureStoreTracker.resetModified() method for the given tracker before returning, as it will be used to track the next proc wal file's modified procedures.
