name:           hasql-queue
version:        1.0.1
synopsis:       A PostgreSQL backed queue
description:    This module utilize PostgreSQL to implement a durable queue for efficently processing arbitrary payloads which can be represented as JSON.
                .
                Typically a producer would enqueue a new payload as part of larger database
                transaction
                .
                >  createAccount userRecord = do
                >     'runDBTSerializable' $ do
                >        createUserDB userRecord
                >        'enqueueDB' "queue_schema" $ makeVerificationEmail userRecord
                .
                In another thread or process, the consumer would drain the queue.
                .
                >   forever $ do
                >     -- Attempt get a payload or block until one is available
                >     payload <- lock "queue" conn
                >
                >     -- Perform application specifc parsing of the payload value
                >     case fromJSON $ pValue payload of
                >       Success x -> sendEmail x -- Perform application specific processing
                >       Error err -> logErr err
                >
                >     -- Remove the payload from future processing
                >     dequeue "queue" conn $ pId payload
                >
                > To support multiple queues in the same database, the API expects a table name string
                > to determine which queue tables to use.
