Inserting Data into ClickHouse

ClickHouse is a database, so there are countless ways to ingest data. There is no special tool designed just for inserting data into ClickHouse. So how do users get data in? Options include:

  • simply uploading a CSV file to ClickHouse Cloud as discussed in the Quick Start
  • use clickhouse-client or clickhouse-local to retrieve data from a local file, external file, or some other database like MySQL, PostgreSQL, or any ODBC- or JDBC-compatible database
  • write your own client application in your favorite programming language like Java, Golang or Python
  • use one of the technologies listed here in the Ingest section of the docs, like Kafka, Vector, Airbyte, and more
