Data Store

A lightweight in-memory data store in Clojure.

Similar to Redis®* but fewer features.

Run server locally

1. Install Leiningen if you haven't already
2. Install the Redis CLI
3. lein run
4. Open another terminal tab
5. redis-cli PING
6. Expected: PONG
7. Run any other Redis CLI command

Run unit tests

lein test

Package server for production

lein uberjar

Run server in production

java -jar target/uberjar/data-store-<version>-standalone.jar

Benchmark server

1. Run server
2. Open a new terminal tab
3. redis-benchmark -t set,get, -n 1000000 -q
4. Expected:

WARNING: Could not fetch server CONFIG
SET: 72270.00 requests per second, p50=0.343 msec
GET: 74833.49 requests per second, p50=0.351 msec

5. Stop the server you ran in step 1 with Control-C.
6. redis-server
7. Repeat step 3
8. Expected:

SET: 80729.80 requests per second, p50=0.303 msec
GET: 81512.88 requests per second, p50=0.319 msec

9. That's how this server's performance compares to Redis®.
