Summary: Introducing RocksDBLite! Removes all the non-essential features and reduces the binary size. This effort should help our adoption on mobile. Binary size when compiling for IOS (`TARGET_OS=IOS m static_lib`) is down to 9MB from 15MB (without stripping) Test Plan: compiles :) Reviewers: dhruba, haobo, ljin, sdong, yhchiang Reviewed By: yhchiang CC: leveldb Differential Revision: https://reviews.facebook.net/D17835 |

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.
