SSDB-Evolution - A fast NoSQL database, derived from SSDB(https://github.com/ideawu/ssdb), for storing big list of data
Compared with SSDB, SSDB-Evolution has an more comprehensive and better support for redis commands. Most of the codes are rewrited to achieve the improvements listed below.
- Fix some bugs and incompatible implementations
- Full support expiration for all kinds of structs
- Re-implement replication with binlog
- Hot sharding
- Full support DEL for all kinds of sturcts
- Splits metadata with userdata
- Re-implement low-level encoding/decoding for sharding
