Mayank Agarwal f1bf169484 Counter for merge failure ... Summary: With Merge returning bool, it can keep failing silently(eg. While faling to fetch timestamp in TTL). We need to detect this through a rocksdb counter which can get bumped whenever Merge returns false. This will also be super-useful for the mcrocksdb-counter service where Merge may fail. Added a counter NUMBER_MERGE_FAILURES and appropriately updated db/merge_helper.cc I felt that it would be better to directly add counter-bumping in Merge as a default function of MergeOperator class but user should not be aware of this, so this approach seems better to me. Test Plan: make all check Reviewers: dnicholas, haobo, dhruba, vamsi CC: leveldb Differential Revision: https://reviews.facebook.net/D12129		12 years ago
