Iceberg

Slack

Iceberg is a high-performance format for huge analytic tables. Iceberg brings the reliability and simplicity of SQL tables to big data, while making it possible for engines like Spark, Trino, Flink, Presto, Hive and Impala to safely work with the same tables, at the same time.

Background and documentation is available at https://iceberg.apache.org

Status

Iceberg is under active development at the Apache Software Foundation.

The Iceberg format specification is stable and new features are added with each version.

The core Java library is located in this repository and is the reference implementation for other libraries.

Documentation is available for all libraries and integrations.

Collaboration

Iceberg tracks issues in GitHub and prefers to receive contributions as pull requests.

Community discussions happen primarily on the dev mailing list or on specific issues.

Building

Iceberg is built using Gradle with Java 8, 11, or 17.

  • To invoke a build and run tests: ./gradlew build
  • To skip tests: ./gradlew build -x test -x integrationTest
  • To fix code style for default versions: ./gradlew spotlessApply
  • To fix code style for all versions of Spark/Hive/Flink:./gradlew spotlessApply -DallModules

Iceberg table support is organized in library modules:

  • iceberg-common contains utility classes used in other modules
  • iceberg-api contains the public Iceberg API
  • iceberg-core contains implementations of the Iceberg API and support for Avro data files, this is what processing engines should depend on
  • iceberg-parquet is an optional module for working with tables backed by Parquet files
  • iceberg-arrow is an optional module for reading Parquet into Arrow memory
  • iceberg-orc is an optional module for working with tables backed by ORC files
  • iceberg-hive-metastore is an implementation of Iceberg tables backed by the Hive metastore Thrift client
  • iceberg-data is an optional module for working with tables directly from JVM applications

Iceberg also has modules for adding Iceberg support to processing engines:

  • iceberg-spark is an implementation of Spark's Datasource V2 API for Iceberg with submodules for each spark versions (use runtime jars for a shaded version)
  • iceberg-flink contains classes for integrating with Apache Flink (use iceberg-flink-runtime for a shaded version)
  • iceberg-mr contains an InputFormat and other classes for integrating with Apache Hive
  • iceberg-pig is an implementation of Pig's LoadFunc API for Iceberg

NOTE

The tests require Docker to execute. On MacOS (with Docker Desktop), you might need to create a symbolic name to the docker socket in order to be detected by the tests:

sudo ln -s $HOME/.docker/run/docker.sock /var/run/docker.sock

Engine Compatibility

See the Multi-Engine Support page to know about Iceberg compatibility with different Spark, Flink and Hive versions. For other engines such as Presto or Trino, please visit their websites for Iceberg integration details.

Iceberg

Slack

Iceberg is a high-performance format for huge analytic tables. Iceberg brings the reliability and simplicity of SQL tables to big data, while making it possible for engines like Spark, Trino, Flink, Presto, Hive and Impala to safely work with the same tables, at the same time.

Background and documentation is available at https://iceberg.apache.org

Status

Iceberg is under active development at the Apache Software Foundation.

The Iceberg format specification is stable and new features are added with each version.

The core Java library is located in this repository and is the reference implementation for other libraries.

Documentation is available for all libraries and integrations.

Collaboration

Iceberg tracks issues in GitHub and prefers to receive contributions as pull requests.

Community discussions happen primarily on the dev mailing list or on specific issues.

Building

Iceberg is built using Gradle with Java 8, 11, or 17.

  • To invoke a build and run tests: ./gradlew build
  • To skip tests: ./gradlew build -x test -x integrationTest
  • To fix code style for default versions: ./gradlew spotlessApply
  • To fix code style for all versions of Spark/Hive/Flink:./gradlew spotlessApply -DallModules

Iceberg table support is organized in library modules:

  • iceberg-common contains utility classes used in other modules
  • iceberg-api contains the public Iceberg API
  • iceberg-core contains implementations of the Iceberg API and support for Avro data files, this is what processing engines should depend on
  • iceberg-parquet is an optional module for working with tables backed by Parquet files
  • iceberg-arrow is an optional module for reading Parquet into Arrow memory
  • iceberg-orc is an optional module for working with tables backed by ORC files
  • iceberg-hive-metastore is an implementation of Iceberg tables backed by the Hive metastore Thrift client
  • iceberg-data is an optional module for working with tables directly from JVM applications

Iceberg also has modules for adding Iceberg support to processing engines:

  • iceberg-spark is an implementation of Spark's Datasource V2 API for Iceberg with submodules for each spark versions (use runtime jars for a shaded version)
  • iceberg-flink contains classes for integrating with Apache Flink (use iceberg-flink-runtime for a shaded version)
  • iceberg-mr contains an InputFormat and other classes for integrating with Apache Hive
  • iceberg-pig is an implementation of Pig's LoadFunc API for Iceberg

NOTE

The tests require Docker to execute. On MacOS (with Docker Desktop), you might need to create a symbolic name to the docker socket in order to be detected by the tests:

sudo ln -s $HOME/.docker/run/docker.sock /var/run/docker.sock

Engine Compatibility

See the Multi-Engine Support page to know about Iceberg compatibility with different Spark, Flink and Hive versions. For other engines such as Presto or Trino, please visit their websites for Iceberg integration details.
