Pentaho Data Integration (Kettle)

Welcome to the community home for Pentaho Data Integration Community Edition (PDI CE) also known as Kettle. Pentaho Data Integration delivers powerful Extraction, Transformation and Loading (ETL) capabilities using an innovative, metadata-driven approach. With an intuitive, graphical, drag and drop design environment, and a proven, scalable, standards-based architecture, Pentaho Data Integration is increasingly the choice for organizations over traditional, proprietary ETL or data integration tools.

Community Edition is self supported open source software. An Enterprise Edition (EE) of Pentaho Data Integration including technical support, managed upgrades and enterprise features is also available. For more information about EE or for screenshots and datasheets, visit Pentaho Data Integration EE on Pentaho's corporate site.

  • Excel Writer step has advanced output functionality to control the look and feel.
  • Graphical performance and progress feedback for transformations
  • Google Analytics step allows download of statistics from your Google analytics account
  • Pentaho Reporting Output step makes it possible for you to run your (parameterized) Pentaho reports in a transformation. It allows for easy report bursting of personalized reports.
  • Automatic Documentation step generates (simple) doc of your transformations and jobs.
  • Get repository names step retrieves job and transformation information from your repositories.
  • LDAP Writer step
  • Ingres VectorWise (streaming) bulk loader step
  • Greenplumb (streaming) bulk loader step (for gpload)
  • Talend Job Execution job entry
  • Healthcare Level 7 : HL7 Input step, HL7 MLLP Input and HL7 MLLP Acknowledge job entries
  • PGP File Encryption, Decryption & validation job entries.
  • Single Threader step for parallel performance tuning of large transformations
  • Allow a job to be started at a job entry of your choice (continue after fixing an error)
  • MongoDB Input step (including authentication)
  • ElasticSearch bulk loader
  • XML Input Stream (StAX) step to read huge XML files at optimal performance and flat memory usage by flattening the structure of the data.
  • Get ID from Slave Server step allows multi-host or clustered transformations to get globally unique integer IDs from a slave server: See wiki doc for more info
  • Memory tuning of logging back-end with: KETTLE_MAX_LOGGING_REGISTRY_SIZE, KETTLE_MAX_JOB_ENTRIES_LOGGED, KETTLE_MAX_JOB_TRACKER_SIZE allowing for flat memory usage for never ending ETL in general and jobs specifically.
  • Multiway Merge Join step (experimental) allows for any number of data sources to be joined using one or more keys using an inner or a full outer join algorithm.
Carte improvements:
  • reserve next value range from a slave sequence service
  • allow parallel (simultaneous) runs of clustered transformations
  • list (reserved and free) socket reservations service
  • new options in XML for configuring slave sequences
  • allow time-out of stale objects using environment variable KETTLE_CARTE_OBJECT_TIMEOUT_MINUTES
Repository Import/Export:
  • Export at the repository folder level
  • Export and Import with optional rule-based validations
  • Import command line utility allow for rule-based (optional) import of lists of transformations, jobs and repository export files: See wiki doc for more info
ETL Metadata Injection:
  • Retrieval of rows of data from a step to the “metadata injection” step
  • Support for injection into the “Excel Input” step
  • Support for injection into the “Row normaliser” step
  • Support for injection into the “Row Denormaliser” step
Many bug fixes. See Release Notes for 4.2.0 for more info
