Short Description
SnappyData, the Spark Database. Stream - Transact - Analyze - Predict all in one cluster
Full Description

SnappyData is a high performance in-memory data platform for mixed workload applications. Built on Apache Spark, SnappyData provides a unified programming model for streaming, transactions, machine learning and SQL Analytics in a single cluster. SnappyData unifies real time data sources with external data sources that have a Spark connector. SnappyData is 100% compatible with Apache Spark and is Open Sourced with an Apache V2 license.

Start a basic cluster with one data node, one lead and one locator

For Linux

 $ docker run -itd --net=host --name snappydata snappydatainc/snappydata start all

For Mac OS

Run the following command to start SnappyData Cluster on Mac OS:

 docker run -d --name=snappydata -p 4040:4040 -p 1527:1527 -p 1528:1528 snappydatainc/snappydata start all -J-Dgemfirexd.hostname-for-clients=<Machine_IP/Public_IP>

The -J-Dgemfirexd.hostname-for-clients parameter sets the IP Address or Host name that this server listens on for client connections.

Note: It may take some time for this command to complete execution.

  1. Check the Docker Process

    $ docker ps -a
    
  2. Check the Docker Logs

    Run the following command to view the logs of the container process.

    $ docker logs snappydata
    starting sshd service
    Starting sshd:
    [ OK ]

    The query results display Distributed system now has 3 members.

  3. Connect SnappyData with the Command Line Client

    $ docker exec -it snappydata ./bin/snappy-shell
    
  4. Connect Client on port “1527”

    $ snappy> connect client 'localhost:1527';
    
  5. View Connections

    snappy> show connections;
    CONNECTION0* -
    jdbc:gemfirexd://localhost[1527]/
    * = current connection
