nabeken/delayd2 repository overview

⁠delayd2

delayd2 is an available setTimeout() service for scheduling message sends.

delayd2 stores scheduling information on clustered (aka streaming replication) PostgreSQL instances as a stable storage layer. MySQL (or Amazon Aurora) support is also planned.

⁠Message Format

Message bodies are forwarded unchanged from received messages after their delay elapses.

All Delayd directives are taken from SQS Message Attributes⁠.

⁠Required Message Attributes

• delayd2-delay (Integer): Delay time in second before emitting this message.
• delayd2-relay-to (String): Queue name for relaying this message.

⁠Acknowledgement and License

delayd2 is my whole rework against nabeken/delayd⁠ which was an fork of goinstant/delayd⁠.
