History

Dmitri Smirnov 18285c1e2f Windows Port from Microsoft Summary: Make RocksDb build and run on Windows to be functionally complete and performant. All existing test cases run with no regressions. Performance numbers are in the pull-request. Test plan: make all of the existing unit tests pass, obtain perf numbers.

README

This folder defines a REDIS-style interface for Rocksdb.
Right now it is written as a simple tag-on in the rocksdb::RedisLists class.
It implements Redis Lists, and supports only the "non-blocking operations".

Internally, the set of lists are stored in a rocksdb database, mapping keys to
values. Each "value" is the list itself, storing a sequence of "elements".
Each element is stored as a 32-bit-integer, followed by a sequence of bytes.
The 32-bit-integer represents the length of the element (that is, the number
of bytes that follow). And then that many bytes follow.


NOTE: This README file may be old. See the actual redis_lists.cc file for
definitive details on the implementation. There should be a header at the top
of that file, explaining a bit of the implementation details.
