liteq

Lightweight Portable Message Queue Using 'SQLite'

v1.1.0 · Mar 8, 2019 · MIT + file LICENSE

Description

Temporary and permanent message queues for R. Built on top of 'SQLite' databases. 'SQLite' provides locking, and makes it possible to detect crashed consumers. Crashed jobs can be automatically marked as "failed", or put in the queue again, potentially a limited number of times.
