Hi Kunal,
 I have some questions.

*Problem(Locking):*
  Does the memory lock support that the multiple drivers concurrently load
data to the same table? maybe it should note this limitation.
   
*Problem(Write with append mode):*
  1. atomicity
  After the overwrite operation failed, maybe the old file is destroyed. It
should be able to recover the old file.

*Problem(Alter rename):*
    If the table folder is different with the table name, maybe "refresh
table" command should be enhanced.
