Redka aims to reimplement the good parts of Redis with SQLite, while remaining compatible with the Redis API. This release adds support for list commands and improves throughput quite a bit (+20% for writes, +60% for reads).
All commands are available via the Redis wire protocol (RESP) and the Go API.

Special thanks to @yinzhidong for implementing the PING command.
Lists
Redka supports the following list-related commands:
LINDEX- Returns an element from a list by its index.LINSERT- Inserts an element before or after another element in a list.LLEN- Returns the length of a list.LPOP- Returns the first element of a list after removing it.LPUSH- Prepends an element to a list.LRANGE- Returns a range of elements from a list.LREM- Removes elements from a list.LSET- Sets the value of an element in a list by its index.LTRIM- Removes elements from both ends a list.RPOP- Returns the last element of a list after removing it.RPOPLPUSH- Removes the last element and pushes it to another list.RPUSH- Appends an element to a list.
⚠️ Breaking changes
Until Redka reaches 1.0, I may introduce breaking changes with each release. Sorry for that.
rkey.DB / rkey.Tx interface changes:
- Scan(cursor int, pattern string, count int) (ScanResult, error)
+ Scan(cursor int, pattern string, ktype core.TypeID, count int) (ScanResult, error)
- Scanner(pattern string, pageSize int) *Scanner
+ Scanner(pattern string, ktype core.TypeID, pageSize int) *Scanner
There are also some non-backward-compatible database schema changes, and I'd rather not introduce automated migrations until 1.0. If you are already using Redka in production and need a migration, let me know in the issues.
