Definitely we need normalization for clickhouse! Is there any way to stay on old version of clickhouse connection until normalization will be implemented? |

Strong +1 on this, we would benefit greatly from typing and deduping on ClickHouse as a destination. |

FYI: The airbyte team published the connector docker images on dockerhub. You can 'revert' to an older connector version (with normalization for example) by uploading it's older image as a custom connector. See clickhouse connector images here cc @asimumba @kvosha |

I've spent hours debugging why the final tables were not created before finding this discussion. |

I can't understand why this feature is removed. Please bring this back in destination v2. For anyone wants this feature, you can go back to version 0.2.5 of clickhouse destination. Note that you'll be switched back to destination v1. |

ok, Downgraded Airbyte to 0.63.3, works again - with 0.63.9 the "transformation" tab was lost despite the downgrade of the clickhouse Destination. |

Please bring it back, I've spent countless hours trying to figure out what is wrong with my setup! We really need this for ClickHouse. |

Can we fix the docs? They currently say that dedupe mode is supported https://docs.airbyte.com/integrations/destinations/clickhouse |

guys do not rely on airbyte I did it I figured out a way to normalize it but it is using dbt so instead of ETL you guys will have to rely on ELT |
Beta Was this translation helpful? Give feedback.

+1 this is drastically needed. ETL without the T just becomes the. Clickhouse (self-hosted and cloud) is one of the fastest performing columnar stores for analytics. If we're evaluating entire new ETL/schedulers/implementing ELT we might as well eval moving off Airbyte (self hosted or enterprise). And ELT isn't the solve, because without dedupe, streams with high velocity of change will result in large raw datasets with many duplicates. Yes you can ELT to new tables and sort/dedupe on primary keys, but that reinforces the need for standing up a job scheduler stack with dbt where it wasn't required at all previously. |

Yes, please integrate Typing and Deduping to Clickhouse. It is essential. Without the functionality, Airbyte becomes less attractive. |

Yes, I saw your article, it's good! But still it would be better to avoid the additional effort in future. |

Is there any information available about whether and when the Clickhouse destination will be updated to support the typing and deduping functionality? I think this is a rather critical feature across Airbyte and should be the default behavior for all supported destinations. |

I just saw that it's on their roadmap for Feb. - May 2025 so I am guessing it's reasonable to exepect more information around that time. |

any other good alternatives until this is actually working again -.- |

I made a solution on how to transform the raw airbyte file using DBT and it is 100% dynamic just provide the db name and run the script and everything will be done ELT pipeline between source to airbyte to clickhouse |

-
|
Any update here from the Airbyte team? Great that there's lots of other scripted solutions, but if we're setting up dbt etc and running them in schedulers like Airflow, might as well setup us dlt etc, and no longer use Airbyte if Clickhouse is a destination. |

-
|
That’s exactly what I did, in the end. Running dlt and dbt on Airflow gave us less tools to work with and roughly a 500% increase in performance due to how fast dlt runs with pyarrow as backend - and in parallel! - compared to old Java-connectors that does one table at a time. |

Any chance this get attention? No way for us to keep using Airbyte if its not handled. |

Hey guys, did you find any other alternatives for airbyte? (free open source) |

Not using AirByte at all. They don't seem to care about something broken for months that was perfectly working before. |

We migrated to dlt. Orders of magnitude faster and can move multiple tables in parallel. |

Also moving to Meltano |

tell me is meltano faster? and does it provide rest API access like airbyte? or is it just cli based? |

Hi, everyone! We're working on ClickHouse this cycle. This is one of our most upvoted requests ever and we definitely haven't forgotten about it! I won't speculate on a delivery date at this early stage, but I do hope to be able to do said speculation soon. 👨💻 👩💻 🧑💻 |

We removed (PR )"normalization" from Destination Clickhouse. Normalization was a process which would extract data from the raw json format and cast the data into tables with the appropriate types. For other destinations, we implemented Typing and Deduping to replace normalization and we will bring typing and deduplication to Clickhouse if there is sufficient interest
The purpose of this discussion is to gauge interest in bringing this functionality back to Clickhouse.
Without typing and deduping, you would need to integrate another tool, such as dbt to accomplish the same result. While integrating another tool gives you greater customization over the data format, it comes with additional operational overhead.
Should Airbyte bring Typing and Deduping to Clickhouse?
Update: We're actively working on this.
