Siying Dong 51dd21926c DB::Put() to estimate write batch data size needed and pre-allocate buffer ... Summary: In one of CPU profiles, we see some CPU costs of string::reserve() inside Batch.Put(). This patch should be able to reduce some of the costs by allocating sufficient buffer before hand. Since it is a trivial percentage of CPU costs, I didn't find a way to show the improvement in one of the benchmarks. I'll deploy it to same application and do the same CPU profiling to make sure those CPU costs are reduced. Test Plan: make all check Reviewers: haobo, kailiu, igor Reviewed By: haobo CC: leveldb, nkg- Differential Revision: https://reviews.facebook.net/D15135		11 years ago
