Apache Hop 2.9.0 comes with a lot of bug fixes, code hardening and a couple of new features.

Static Schema

Static Schema Metadata Type

One of the first things new Apache Hop users learn when reading data from files is to use the Get Fields button to detect a file’s layout.

Even though this is a straightforward way to get a decent estimate of schemaless input files, sometimes you know what the layout of a file is, and just want to apply a known layout to your file.

The new Static Schema Definition in Apache Hop 2.9.0 lets you do just that: create a static file definition, and use that definition to specify the layout in your input transforms.

After a static schema definition has been created in the metadata perspective, it can be used in transforms like the Text File Input, CSV Input, Excel Input and more.

Schema Mapping transform

The Static Schema Mapping transform lets you map your current stream to a Static Schema Definition.

Fields that are available in the Static Schema Definition but not in your input stream are added with empty (null) values.

CrateDB database dialect and bulk loader


CrateDB is an enterprise database for time series, documents and vectors, based on PostgreSQL.

Apache Hop 2.9.0 comes with a new CrateDB database dialect and a new CrateDB Bulk Loader transform.

The bulk loader uses the CrateDB HTTP endpoint or COPY command for bulk loading.

CrateDB Bulk Loader


  • The REST transform now supports a configurable timeout

  • The database join transform now supports caching

  • Azure blob storage improvements

  • Redshift Bulk Loader dialog was rewritten to align with the CrateDB bulk loader

  • Improvements in database schema/table listing widget

  • Lots of new and updated translations
