-- Open in-memory database
local db = redlite.open(":memory:")

-- Or file-based

-- String operations
db:set("key", "value")
local val = db:get("key")
print(val)  -- "value"

db:incr("counter")
db:incrby("counter", 5)

-- Hash operations
db:hset("user:1", "name", "Alice")
db:hset("user:1", "age", "30")

-- List operations
db:lpush("queue", "job1", "job2")
local job = db:rpop("queue")

-- Set operations
db:sadd("tags", "redis", "sqlite")
local members = db:smembers("tags")

-- Sorted sets
db:zadd("scores", 100, "player1")
db:zadd("scores", 85, "player2")
