Redka aims to reimplement the core parts of Redis with SQL, while remaining compatible with the Redis API. This release adds support for PostgreSQL! Now, Redka can use either SQLite or Postgres as a backend.
Postgres backend
Here's an example in Go:
// Prepate connection settings.
connStr := "postgres://user:password@localhost:5432/mydb?sslmode=disable"
opts := &redka.Options{DriverName: "postgres"}
// Connect to the database.
db, _ := redka.Open(connStr, opts)
defer db.Close()
// Set some values.
db.Str().Set("name", "alice")
db.Str().Set("age", 25)
// Read them back.
name, _ := db.Str().Get("name")
fmt.Printf("name = %v\n", name)
age, _ := db.Str().Get("age")
fmt.Printf("age = %v\n", age)name = alice
age = 25
You can also run Redka as a standalone Redis-compatible server backed by Postgres, to use with Python, JavaScript, C# or any other language:
export REDKA_DB_URL="postgres://redka:redka@localhost:5432/redka?sslmode=disable"
./redka -h localhost -p 6379
The Postgres backend supports all the data structures that Redka offers: strings, lists, sets, hashes and sorted sets (zsets).
Other changes
The new redsrv package provides a convenient API for creating and starting a Redka server. This is useful if you want to run the Redka server within your own Go application, either for testing or as a lightweight alternative to real Redis. See the server example for details.
Until Redka reaches 1.0, I may introduce breaking changes with each release. Sorry about that.
