effectful-data-cache

import Effectful
import Effectful.Cache
import Prelude hiding (lookup)

main :: IO ()
main = runEff . runCache Nothing $ do
  insert "key" (42 :: Int)
  v <- lookup @String @Int "key"
  liftIO $ print v

runCache creates a fresh store; runCacheWith wraps an existing Data.Cache.Cache so it can be shared with non-effectful code.

Tracing

See effectful-data-cache-opentelemetry for OpenTelemetry instrumentation.

memcached

See effectful-data-cache-memcache for a memcached backend.
