Haste

A simple alarm/scheduler using Redis simple set and 1-d vector calculation. An alarm service allows users or other services to persist Alarm Item(s) as time-based events in a mem-cached Priority Queue. When the period specified in the alarm expires, it sends the message to the endpoint specified in the alarm when it was initially set. The communication is supported for GRPC, REST and Message Queue.

Open two terminal in Github Codespaces. The first terminal will be used to bring up the Haste service and the redis service. The second one is used to stress test the Haste service.

Step 1: Run docker compose up in the first terminal. Wait for it to complete. The gin server should come up.

Step 2: Run bash scripts\parallel_n.sh in the second terminal. The response can be watched in the first terminal.
