Cassandra

Prerequisites

• For Airbyte Open Source users using the Postgres source connector, upgrade your Airbyte platform to version v0.40.0-alpha or newer and upgrade your Cassandra connector to version 0.1.3 or newer

Sync overview

Output schema

The incoming airbyte data is structured in keyspaces and tables and is partitioned and replicated across different nodes in the cluster. This connector maps an incoming stream to a Cassandra table and a namespace to a Cassandrakeyspace. Fields in the airbyte message become different columns in the Cassandra tables. Each table will contain the following columns.

• _airbyte_ab_id: A random uuid generator to be used as a partition key.
• _airbyte_emitted_at: a timestamp representing when the event was received from the data source.
• _airbyte_data: a json text representing the extracted data.

Performance considerations

Cassandra is designed to handle large amounts of data by using different nodes in the cluster in order to perform write operations. As long as you have enough nodes in the cluster the database can scale infinitely and handle any amount of data from the connector.

Getting started

Requirements

• The driver is compatible with Cassandra >= 2.1
• Configuration
  • Keyspace [default keyspace to use when writing data]
  • Username [authentication username]
  • Password [authentication password]
  • Address [cluster address]
  • Port [default: 9042]
  • Datacenter [optional] [default: datacenter1]
  • Replication [optional] [default: 1]

Namespace support

This destination supports namespaces. The namespace maps to a Cassandra keyspace and is used as part of the table name.
