Maysam Yabandeh	bdc056f8aa	Refactor PessimisticTransaction ... Summary: This patch splits Commit and Prepare into lock-related logic and db-write-related logic. It moves lock-related logic to PessimisticTransaction to be reused by all children classes and movies the existing impl of db-write-related to PrepareInternal, CommitSingleInternal, and CommitInternal in WriteCommittedTxnImpl.

Closes https://github.com/facebook/rocksdb/pull/2689 Differential Revision: D5568918 Pulled By: maysamyabandeh fbshipit-source-id: f7eac866e175daf3793ae79da108f65cc7dc7b25	2017-08-05 17:26:15 -07:00
Maysam Yabandeh	c3d5c4d38a	Refactor TransactionImpl ... Summary: This patch refactors TransactionImpl by separating the logic for pessimistic concurrency control from the implementation of how to write the data to rocksdb. The existing implementation is named WriteCommittedTxnImpl as it writes committed data to the db. A template named WritePreparedTxnImpl is also added which will be later completed to provide a an alternative implementation.
