It will locked the database file during updating. In our cases, multiple modules/threads may update metastore at the same time, which ends up with database exceptions. \r\n\r\nNote that SQLite is introduced as a temp metastore for Unit test in SSM.  Also, this issue will not effect any feature, but it has tripped us from a few weeks. :(\r\n\r\n\r\n"}}
