# squirrel

Flink window word count example in Clojure, reading text data from a local socket

and printing counts every 10 seconds.

Run local tests:

```

lein test

```

Build the Flink job:

```

lein uberjar

```

Start a local Flink cluster and a local netcat server:

```

$FLINK_HOME/bin/start-cluster.sh

nc -l -p 9000

```

Run the Flink job:

```

$FLINK_HOME/bin/flink run target/squirrel-0.1.0-standalone.jar 9000

```

Type some text in the netcat socket, check the results in Flink's logs:

```

tail -f $FLINK_HOME/log/flink-*-taskexecutor-*.out

```
