Apache Kafka

tap-kafka (airbyte variant)🥈

Open-source distributed event streaming platform

The tap-kafka extractor pulls data from Apache Kafka that can then be sent to a destination using a loader.

Airbyte Usage Notice

This connector uses tap-airbyte-wrapper to call the underlying Airbyte source Docker container. This means you must have Docker installed and running prior to usage. We also recommend using Meltano version 2.13.0 or later.

Container-based connectors can introduce deployment challenges including the potential need to run Docker-in-Docker (not currently supported by services like AWS ECS, Meltano Cloud, etc. see FAQ and Airbyte's ECS deployment docs for more details). Before using this variant we recommend considering if/how you will be able to deploy container-based connectors to production.

For more context on how this Airbyte integration works please checkout out the FAQ in the Meltano Docs.

Airbyte Config Auto Commit Interval Ms (airbyte_config.auto_commit_interval_ms)

  • Environment variable: TAP_KAFKA_AIRBYTE_CONFIG_AUTO_COMMIT_INTERVAL_MS

Configure this setting directly using the following Meltano command:

meltano config tap-kafka set airbyte_config auto_commit_interval_ms [value]

Airbyte Config Auto Offset Reset (airbyte_config.auto_offset_reset)

  • Environment variable: TAP_KAFKA_AIRBYTE_CONFIG_AUTO_OFFSET_RESET

What to do when there is no initial offset in Kafka or if the current offset does not exist any more on the server - earliest: automatically reset the offset to the earliest offset, latest: automatically reset the offset to the latest offset, none: throw exception to the consumer if no previous offset is found for the consumer's group, anything else: throw exception to the consumer.


Configure this setting directly using the following Meltano command:

meltano config tap-kafka set airbyte_config auto_offset_reset [value]

Airbyte Config Bootstrap Servers (airbyte_config.bootstrap_servers)

  • Environment variable: TAP_KAFKA_AIRBYTE_CONFIG_BOOTSTRAP_SERVERS

A list of host/port pairs to use for establishing the initial connection to the Kafka cluster. The client will make use of all servers irrespective of which servers are specified here for bootstrapping—this list only impacts the initial hosts used to discover the full set of servers. This list should be in the form host1:port1,host2:port2,.... Since these servers are just used for the initial connection to discover the full cluster membership (which may change dynamically), this list need not contain the full set of servers (you may want more than one, though, in case a server is down).


Configure this setting directly using the following Meltano command:

meltano config tap-kafka set airbyte_config bootstrap_servers [value]

Airbyte Config Client Dns Lookup (airbyte_config.client_dns_lookup)

  • Environment variable: TAP_KAFKA_AIRBYTE_CONFIG_CLIENT_DNS_LOOKUP

Controls how the client uses DNS lookups. If set to use_all_dns_ips, connect to each returned IP address in sequence until a successful connection is established. After a disconnection, the next IP is used. Once all IPs have been used once, the client resolves the IP(s) from the hostname again. If set to resolve_canonical_bootstrap_servers_only, resolve each bootstrap address into a list of canonical names. After the bootstrap phase, this behaves the same as use_all_dns_ips. If set to default (deprecated), attempt to connect to the first IP address returned by the lookup, even if the lookup returns multiple IP addresses.


Configure this setting directly using the following Meltano command:

meltano config tap-kafka set airbyte_config client_dns_lookup [value]

Airbyte Config Client Id (airbyte_config.client_id)

  • Environment variable: TAP_KAFKA_AIRBYTE_CONFIG_CLIENT_ID
