ClickHouse

Airbyte writes to ClickHouse over its native binary protocol with batch inserts. The setup needs a hostname, a port, and a user. No object storage, no staging permissions, no intermediate hop.

How it works

How do you load data into ClickHouse with Airbyte?

Create a user, grant it, point Airbyte at your host. There is no bucket to provision and no storage integration to configure.

01

Create a dedicated user.

Create an airbyte_user rather than reusing an existing one. Set async_insert = 0 on it, which the connector requires for connection checks and syncs to work correctly when async inserts are enabled on the server.
02

Grant permissions.

The user needs CREATE, ALTER, TRUNCATE, INSERT, SELECT, CREATE DATABASE, CREATE TABLE, and DROP TABLE on the target database. Repeat the same grants for any custom namespace.
03

Configure the destination.

Add ClickHouse as a destination in Airbyte and supply the connection details. Then select your streams and run the first sync.

How it works

What happens to your grants when Airbyte syncs?

Not a philosophy. A set of specific, verifiable guarantees about the infrastructure your data runs on.

  • No staging bucket.

    The connector’s requirements are a ClickHouse instance, network access, and a user. Object storage is not among them.

  • Typed columns, not JSON blobs.

    Direct Load writes data into columns matching your source schema rather than storing everything as JSON in raw tables.

  • Batched for throughput.

    Batches are capped at 70 MB, and record window size is tunable if you need to.

Airbyte versus ClickHouse’s native ingestion options

ClickHouse has excellent first-party ingestion for the shapes it was designed around, particularly Kafka and object storage. The gap is everything that starts as a SaaS API.

MethodBest forLimitsUse Airbyte instead when
Kafka table engineStreaming events already on a Kafka topicKafka only. You own the producer and the topicYour data is not on a topic and putting it there is the actual work
s3() and url() table functionsFiles already sitting in object storageYou own extraction, file formatting, and schedulingYour data starts in an API or a database
ClickPipesManaged ingestion on ClickHouse CloudClickHouse Cloud only, and a bounded source listYou are self-hosted, or your source is not covered
PeerDBPostgres change data capture into ClickHousePostgres only. No SaaS connectorsYou need Postgres CDC and SaaS sources in the same cluster
clickhouse-client bulk insertOne-off backfills and manual loadsNot a pipeline. No scheduling, no state, no schema handlingYou need this to keep running after you stop watching it

Where Airbyte wins

Breadth into one cluster. Postgres CDC plus Salesforce, HubSpot, and Zendesk landing in the same ClickHouse database on the same schedule, with schema drift handled, is not something the first-party options cover together.

Where it does not

For a pure Kafka-to-ClickHouse pipeline, the Kafka table engine is closer to the metal and there is no reason to add a hop.

"With our legacy framework, if one of the pipelines fails for one client, it will stop everything for the rest of our clients. But with Airbyte, things are run in parallel because of the platform’s distributed nature, which means that we can process multiple clients at the same time without impacting performance."

How does your data land in ClickHouse?

Airbyte writes typed columns directly, and delegates deduplication to ClickHouse’s own engine rather than running MERGE queries against your cluster.

Schema evolution

  • Column added.

    Airbyte adds the column to the destination table automatically.

  • Type changed.

    Airbyte modifies the column type as needed.

  • Column removed.

    ClickHouse is the exception. Airbyte drops the column and its historical data from the destination table, because ReplacingMergeTree deduplicates by deleting and re-inserting records rather than using MERGE, and that table recreation requires dropping obsolete columns.

Talk to us

If events are already on a Kafka topic, the Kafka table engine is closer to the metal. If files already sit in object storage, s3() and url() table functions are enough. ClickPipes is managed ingestion on ClickHouse Cloud with a bounded source list. PeerDB is Postgres CDC only. If you need Postgres CDC plus Salesforce, HubSpot, and Zendesk in the same cluster on the same schedule, Airbyte covers that together.

No. Airbyte writes over the native binary protocol. The setup needs a hostname, a port, and a user. There is no bucket to provision and no storage integration to configure.

Airbyte uses ReplacingMergeTree, so deduplication happens during ClickHouse’s background merges rather than at write time. To guarantee deduplicated results at query time, add the FINAL operator: SELECT * FROM your_table FINAL. Without it you may see duplicated or deleted rows.

ClickHouse is the exception. Airbyte drops the column and its historical data from the destination table, because ReplacingMergeTree deduplicates by deleting and re-inserting records rather than using MERGE, and that table recreation requires dropping obsolete columns.

Pick a monotonically increasing column the source exposes, such as updated_at or an incrementing id, so Airbyte can request only new or changed rows.

The dedicated user needs CREATE, ALTER, TRUNCATE, INSERT, SELECT, CREATE DATABASE, CREATE TABLE, and DROP TABLE on the target database. Repeat the same grants for any custom namespace.

Yes. Airbyte works with self-hosted ClickHouse. Cloud, Flex, Self-Managed, and PyAirbyte are all supported. Flex and Self-Managed keep the data plane in your environment.

Other destinations

Snowflake

Airbyte clones tables instead of swapping them, so the grants you configured survive every sync. Removed source columns are kept, and oversized values are logged rather than fatal.

Load data into Snowflake

BigQuery

Airbyte stages files in Google Cloud Storage, then loads them into BigQuery with native load jobs. Warehouse compute stays on Google Cloud, and Airbyte never sits in the query path.

Load data into BigQuery

Databricks

Airbyte stages Avro files inside Unity Catalog Volumes, not an external bucket, so your data stays under your catalog’s governance from the first byte to the final table.
