ColumnStore Streaming Data Adapters

The ColumnStore Bulk Data API enable creation of higher performance adapters for ETL integration and data ingestions. The Streaming Data Adapters are out of box adapters using these API for specific data sources and use cases.

• MaxScale CDC Data Adapter is integration of the MaxScale CDC streams into MariaDB ColumnStore.
• Kafka Data Adapter is integration of the Kafka streams into MariaDB ColumnStore.

MaxScale CDC Data Adapter

Installation

CentOS 7

sudo yum -y install <data adapter>.rpm

Debian 9/Ubuntu Xenial:

sudo apt-get update
sudo dpkg -i <data adapter>.deb
sudo apt-get -f install

Debian 8:

sudo echo "deb http://httpredir.debian.org/debian jessie-backports main contrib non-free" >> /etc/apt/sources.list
sudo apt-get update

sudo apt-get -f install

Usage

Usage: mxs_adapter [OPTION]... DATABASE TABLE

  DATABASE       Source & Target database
  TABLE          Table to stream

  -h HOST      MaxScale host
  -P PORT      Port number where the CDC service listens
  -u USER      Username for the MaxScale CDC service
  -p PASSWORD  Password of the user
  -c CONFIG    Path to the Columnstore.xml file (installed by MariaDB ColumnStore)
  -r ROWS      Number of events to group for one bulk load (default: 1)
  -t TIMEOUT   Timeout in seconds (default: 10)

Quick Start

Download and install both MaxScale and ColumnStore.

Copy the Columnstore.xml file from /usr/local/mariadb/columnstore/etc/Columnstore.xml from one of the ColumnStore UM or PM node to the server where the adapter is installed.

Configure MaxScale according to the CDC tutorial.

Create a CDC user by executing the following MaxAdmin command on the MaxScale server. Replace the `<service>` with the name of the avrorouter service and `<user>` and `<password>` with the credentials that are to be created.

maxadmin call command cdc add_user <service> <user> <password>

Then we can start the adapter by executing the following command.

mxs_adapter -u <user> -p <password> -h <host> -P <port> -c <path to Columnstore.xml> <database><table>

The `<database>` and `<table>` define the table that is streamed to ColumnStore. This table should exist on the master server where MaxScale is reading events from. If the table is not created on ColumnStore, the adapter will print instructions on how to define it in the correct way.

The `<user>` and `<password>` are the users created for the CDC user, `<host>` is the MaxScale address and `<port>` is the port where the CDC service listener is listening.

The `-c` flag is optional if you are running the adapter on the server where ColumnStore is located.
