With this patch an index partition is cut before its estimated in-memory size goes above the configured value for metadata_block_size. The filter partitions are still cut right after an index partition is cut.

Summary:
Added fifo benchmark to db_bench.
One thing i am not sure is that i am using CompactRange() instead of CompactFiles(). (may cause performance skew because CompactionRange() is not happening in current thread?) For CompactFiles(), for some reason FIFO compaction doesn't work as expected. More insight is welcomed. I guess FIFO compaction doesn't work with file names? igorcanadi

Summary:
I've added functions to the C API to support WriteBatchWithIndex as requested in #1833.
I've also added unit tests to c_test
I've implemented the WriteBatchWithIndex variation of every function available for regular WriteBatch. And added additional functions unique to WriteBatchWithIndex.
For now, the following is omitted:
1. The ability to create WriteBatchWithIndex's custom batch-only iterator as I'm not sure what its purpose is. It should be possible to add later if anyone wants it.
2. The ability to create the batch with a fallback comparator, since it appears to be unnecessary. I believe the column family comparator will be used for this, meaning those using a custom comparator can just use the column family variations.

Summary:
MemTableInserter default constructs Post processing info
std::map. However, on Windows with 2015 STL the default
constructed map still dynamically allocates one node
which shows up on a profiler and we loose ~40% throughput
on fillrandom benchmark.
Solution: declare a map as std::aligned storage and optionally
construct.

Summary:
Previously, when DB write buffer size triggers, we always pick the CF with most data in its memtable to flush. This approach can minimize total flush happens. Change the behavior to always pick the oldest unflushed CF, which makes it the same behavior when max_total_wal_size hits. This approach will minimize size used by max_total_wal_size.

PinnableSlice
Summary:
Currently the point lookup values are copied to a string provided by the
user. This incures an extra memcpy cost. This patch allows doing point lookup
via a PinnableSlice which pins the source memory location (instead of
copying their content) and releases them after the content is consumed
by the user. The old API of Get(string) is translated to the new API
underneath.
Here is the summary for improvements:
value 100 byte: 1.8% regular, 1.2% merge values
value 1k byte: 11.5% regular, 7.5% merge values
value 10k byte: 26% regular, 29.9% merge values
The improvement for merge could be more if we extend this approach to
pin the merge output and delay the full merge operation until the user
actually needs it. We have put that for future work.
PS:
Sometimes we observe a small decrease in performance when switching from
t5452014 to this patch but with the old Get(string) API. The d
