Subject Tajo storage layer
Date Sat, 01 Feb 2014 14:12:09 GMT
Hi all,

Seems the thread model of tajo storage layer is quite complex.
Each call of StorageManagerFactory.getStorageManager(TajoConf)  creates
one instance of StorageManagerV2,  which creates a scan scheduler thread
and several disk file scan schedulers threads.  Why those threads are
needed? What's their function?  How do those threads work with file
scanners?


Regards,
Min
