A simple tool for emulating disk reading.
Run server with:
go run main.go --path '<glob>'For example, for emulating randomly reading SST files in a rocks DB.
go run main.go --path '/path/to/db/*.sst'POST to /busy for starting a workload.
# running one task, each task would read with speed of 100KB per second.
# it returns an identity in JSON like '{"id": "xxxx"}', DELETE to /busy/:id for removing the workload.
curl localhost:8081/busy -HContent-Type:application/json --data '{"n": 1, "rate_limit": "100KB"}'
