Presto-MapD-Connector makes it possible to query MapD via Presto.

Installation

Requirements

• MapD
• Presto v0.170

Setup

1. Clone this repository and cd into it

   clone git@github.com:NVIDIA/presto-mapd-connector.git
   resto-mapd-connector
   

2. Create a lib directory and copy the mapd jdbc jar into it (mapdjdbc-1.0-SNAPSHOT-jar-with-dependencies.jar)

   r lib
   MAPD_HOME/mapdjdbc-1.0-SNAPSHOT-jar-with-dependencies.jar lib/
   

3. Build/package the project

   package
   

4. Copy the jar to your presto plugin directory

   r $PRESTO_HOME/plugin/mapdjdbc
   resto-mapd-jdbc-1.0-jar-with-dependencies.jar $PRESTO_HOME/plugin/mapdjdbc
   

5. Make a mapdjdbc.properties file

   r -p $PRESTO_HOME/etc/catalog && touch $PRESTO_HOME/etc/catalog/mapdjdbc.properties
   

6. In the properties file, enter your credentials to connect to mapd…

   ector.name=mapdjdbc
   ection-url=jdbc:mapd:localhost:9091:mapd
   ection-user=<username>
   ection-password=<password>
   

7. You can now start mapd and presto with the ability to query mapd from presto!
