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.
