-# Geode Continuous Query Example
-
-This is a simple example that demonstrates Apache Geode's Continuous Queries(CQs) feature.  CQs allow clients to subscribe
-to server-side events using a SQL-like query.  When a client registers a CQ, the client will receive all events that
-modify the query results.
-
-In this example, the client program will first register a CQ with the query 
-`SELECT * FROM /example-region i where i > 70`. The region has keys and values that are both Integer types.
- 
-The program loops, randomly generating two integers to put on the server as the key and value.
- 
-If a value is either created or updated that is greater than 70, the above CQ will trigger the `RandomEventLister`,
-which prints to stdout.
-
-The client will generate data for 20 seconds, close the CQ and Cache, and then exit.
-
-This example assumes you have installed Java and Geode.
-
-## Steps
-
-1. From the `geode-examples/cq` directory, build the example and
-   run unit tests.
-
-        $ ../gradlew build
-
-2. Next start a locator, start a server, and create a region.
-
-        $ gfsh run --file=scripts/start.gfsh
-
-3. Run the example to demonstrate continues queries. W
-
-        $ ../gradlew run
-
-4. Shut down the system.
-
-        $ gfsh run --file=scripts/stop.gfsh
