from immukv import ImmuKVClient, Config

config = Config(
    s3_bucket="your-bucket",
    s3_region="us-east-1",
    s3_prefix=""
)

# Identity functions for JSON values (use custom encoders/decoders for complex types)
def identity(x): return x

with ImmuKVClient(config, identity, identity) as client:
    # Write
    entry = client.set("key1", {"value": "data"})
    print(f"Committed: {entry.version_id}")

    # Read
    latest = client.get("key1")
    print(f"Latest: {latest.value}")
