Dhruba Borthakur	f7975ac733	Implement RowLocks for assoc schema ... Summary: Each assoc is identified by (id1, assocType). This is the rowkey. Each row has a read/write rowlock. There is statically allocated array of 2000 read/write locks. A rowkey is murmur-hashed to one of the read/write locks. assocPut and assocDelete acquires the rowlock in Write mode. The key-updates are done within the rowlock with a atomic nosync batch write to leveldb. Then the rowlock is released and a write-with-sync is done to sync leveldb transaction log. Test Plan: added unit test Reviewers: heyongqiang Reviewed By: heyongqiang Differential Revision: https://reviews.facebook.net/D5859	2012-10-03 23:19:01 -07:00
