Summary: The Env registration framework supports registering client Envs and selecting which one to instantiate according to a text field. This enabled things like adding the -env_uri argument to db_bench, so the same binary could be reused with different Envs just by changing CLI config. Now this problem has come up again in a non-Env context, as I want to instantiate a client Statistics implementation from db_bench, which is configured entirely via text parameters. Also, in the future we may wish to use it for deserializing client objects when loading OPTIONS file. This diff generalizes the Env registration logic to work with arbitrary types. - Generalized registration and instantiation code by templating them - The entire implementation is in a header file as that's Google style guide's recommendation for template definitions - Pattern match with std::regex_match rather than checking prefix, which was the previous behavior - Rename functions/files to be non-Env-specific Closes https://github.com/facebook/rocksdb/pull/1776 Differential Revision: D4421933 Pulled By: ajkr fbshipit-source-id: 34647d1

Summary: This diff introduces RangeDelAggregator, which takes ownership of iterators provided to it via AddTombstones(). The tombstones are organized in a two-level map (snapshot stripe -> begin key -> tombstone). Tombstone creation avoids data copy by holding Slices returned by the iterator, which remain valid thanks to pinning. For compaction, we create a hierarchical range tombstone iterator with structure matching the iterator over compaction input data. An aggregator based on that iterator is used by CompactionIterator to determine which keys are covered by range tombstones. In case of merge operand, the same aggregator is used by MergeHelper. Upon finishing each file in the compaction, relevant range tombstones are added to the output file's range tombstone metablock and file boundaries are updated accordingly. To check whether a key is covered by range tombstone, RangeDelAggregator::ShouldDelete() considers tombstones in the key's snapshot stripe. When this function is used outside of compaction, it also checks newer stripes, which can contain covering tombstones. Currently the intra-stripe check involves a linear scan; however, in the future we plan to collapse ranges within a stripe such that binary search can be used. RangeDelAggregator::AddToBuilder() adds all range tombstones in the table's key-range to a new table's range tombstone meta-block. Since range tombstones may fall in the gap between files, we may need to extend some files' key-ranges. The strategy is (1) first file extends as far left as possible and other files do not extend left, (2) all files extend right until either the start of the next file or the end of the last range tombstone in the gap, whichever comes first. One other notable change is adding release/move semantics to ScopedArenaIterator such that it can be used to transfer ownership of an arena-allocated iterator, similar to how unique_ptr is used for malloc'd data.

Summary: Persistent cache tier is the tier abstraction that can work for any block device based device mounted on a file system. The design/implementation can handle any generic block device. Any generic block support is achieved by generalizing the access patten as {io-size, q-depth, direct-io/buffered}. We have specifically tested and adapted the IO path for NVM and SSD. Persistent cache tier consists of there parts : 1) File layout Provides the implementation for handling IO path for reading and writing data (key/value pair). 2) Meta-data Provides the implementation for handling the index for persistent read cache. 3) Implementation It binds (1) and (2) and flushed out the PersistentCacheTier interface This patch provides implementation for (1)(2). Follow up patch will provide (3) and tests. Test Plan: Compile and run check Subscribers: andrewkr, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D57117

Test Plan: Run unit tests. Also, revert db_impl.cc to master (but don't revert `DBImpl::BackgroundCompaction:Finish` sync point) and run db_options_test. Both tests should hit deadlock.

Summary: This provides provides an implementation of PersistentCacheTier that is specialized for RAM. This tier does not persist data though. Why do we need this tier ? This is ideal as tier 0. This tier can host data that is too hot. Why can't we use Cache variants ? Yes you can use them instead. This tier can potentially outperform BlockCache in RAW mode by virtue of compression and compressed cache in block cache doesn't seem very popular. Potentially this tier can be modified to under stand the disadvantage of the tier below and retain data that the tier below is bad at handling (for example index and bloom data that is huge in size) Test Plan: Run unit tests added Subscribers: andrewkr, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D57069
