Spark Agent / Harvester

This module is responsible for listening to spark command events and converting them to spline lineage.

Spark commands

Some events provided by Spark are not yet implemented. Some of them will be implemented in future and some of them bear no lineage information and should be ignored.

All commands inherit from org.apache.spark.sql.catalyst.plans.logical.Command.

You can see how to produce unimplemented commands in za.co.absa.spline.harvester.SparkUnimplementedCommandsSpec.

Implemented

  • CreateDataSourceTableAsSelectCommand (org.apache.spark.sql.execution.command)
  • CÍreateHiveTableAsSelectCommand (org.apache.spark.sql.hive.execution)
  • CreateTableCommand (org.apache.spark.sql.execution.command)
  • DropTableCommand (org.apache.spark.sql.execution.command)
  • InsertIntoDataSourceDirCommand (org.apache.spark.sql.execution.command)
  • InsertIntoHadoopFsRelationCommand (org.apache.spark.sql.execution.datasources)
  • InsertIntoHiveDirCommand (org.apache.spark.sql.hive.execution)
  • InsertIntoHiveTable (org.apache.spark.sql.hive.execution)
  • SaveIntoDataSourceCommand (org.apache.spark.sql.execution.datasources)

To be implemented

  • AlterTableAddColumnsCommand (org.apache.spark.sql.execution.command)
  • AlterTableChangeColumnCommand (org.apache.spark.sql.execution.command)
  • AlterTableRenameCommand (org.apache.spark.sql.execution.command)
  • AlterTableSetLocationCommand (org.apache.spark.sql.execution.command)
  • CreateDataSourceTableCommand (org.apache.spark.sql.execution.command)
  • CreateDatabaseCommand (org.apache.spark.sql.execution.command)
  • CreateTableLikeCommand (org.apache.spark.sql.execution.command)
  • DropDatabaseCommand (org.apache.spark.sql.execution.command)
  • LoadDataCommand (org.apache.spark.sql.execution.command)
  • TruncateTableCommand (org.apache.spark.sql.execution.command)

When one of these commands occurs spline will let you know.

  • When it's running in REQUIRED mode it will throw an UnsupportedSparkCommandException.
  • When it's running in BEST_EFFORT mode it will just log a warning.

Ignored

  • AddFileCommand (org.apache.spark.sql.execution.command)

* SaveIntoDataSourceCommand is produced at the same time and it's already implemented.
