Supported database engines in Aiven for ClickHouse®
A database engine controls how a database manages tables and metadata. It determines what happens when you list, create, or delete tables and can restrict a database to specific table engines or manage replication.
This differs from table engines, which determine how data is stored on disk or read from external sources and exposed as virtual tables.
Aiven for ClickHouse® supports different database engines depending on the service version. Engine availability can differ from upstream depending on features enabled in Aiven for ClickHouse®.
For details about each engine, see the ClickHouse database engines documentation.
