In liteq: Lightweight Portable Message Queue Using 'SQLite'

Description

• id Id of the message, it is generated automatically by the database.

• title The title of the message, can be empty. In the future, it can be used to filter messages.

• message The message, arbitrary text, can be empty.

• status Can be:

  • READY, ready to be consumed

  • WORKING, it is being consumed

  • FAILED, failed.

• requeued How many times the message was requeued.

Usage

db_create_queue(name, db, crash_strategy)

Arguments

name	Name of the queue. If not specified or NULL, a name is generated randomly.
db	Path to the database file.
crash_strategy	What to do with crashed jobs. The default is that they will "fail" (just like a negative acknowledgement). Another possibility is "requeue", in which case they are requeued immediately, potentially even multiple times. Alternatively it can be a number, in which case they are requeued at most the specified number of times.
