Read-uncommitted is happening #588

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Currently, the lockMgr releases locks as soon as the entity-level commit logs 
are written to in-memory log buffers. Consequently, it is possible for readers 
to read tuples whose commit logs are not flushed to disk. When the system 
crashes before the logs are flushed to disk and after the tuples have been read 
by the readers, reader read non-existing tuples.
