  15. def getDeltaLog(spark: SparkSession, path: Option[String], tableIdentifier: Option[TableIdentifier], operationName: String, hadoopConf: Map[String, String] = Map.empty): DeltaLog

    Utility method to return the DeltaLog of an existing Delta table referred by either the given path or tableIdentifier.

    Utility method to return the DeltaLog of an existing Delta table referred by either the given path or tableIdentifier.

    spark

    SparkSession reference to use.

    path

    Table location. Expects a non-empty tableIdentifier or path.

    tableIdentifier

    Table identifier. Expects a non-empty tableIdentifier or path.

    operationName

    Operation that is getting the DeltaLog, used in error messages.

    hadoopConf

    Hadoop file system options used to build DeltaLog.

    returns

    DeltaLog of the table

    Attributes
    protected
    Exceptions thrown

    AnalysisException If either no Delta table exists at the given path/identifier or there is neither path nor tableIdentifier is provided.

  16. def getDeltaTable(target: LogicalPlan, cmd: String): DeltaTableV2

    Extracts the DeltaTableV2 from a LogicalPlan iff the LogicalPlan is a ResolvedTable with either a DeltaTableV2 or a V1Table that is referencing a Delta table.

    Extracts the DeltaTableV2 from a LogicalPlan iff the LogicalPlan is a ResolvedTable with either a DeltaTableV2 or a V1Table that is referencing a Delta table. In all other cases this method will throw a "Table not found" exception.

  17. def getDeltaTablePathOrIdentifier(target: LogicalPlan, cmd: String): (Option[TableIdentifier], Option[String])

    Helper method to extract the table id or path from a LogicalPlan representing a Delta table.

    Helper method to extract the table id or path from a LogicalPlan representing a Delta table. This uses DeltaCommand.getDeltaTable to convert the LogicalPlan to a DeltaTableV2 and then extracts either the path or identifier from it. If the DeltaTableV2 has a CatalogTable, the table identifier will be returned. Otherwise, the table's path will be returned. Throws an exception if the LogicalPlan does not represent a Delta table.

  19. def getTableCatalogTable(target: LogicalPlan, cmd: String): Option[CatalogTable]

    Extracts CatalogTable metadata from a LogicalPlan if the plan is a ResolvedTable.

    Extracts CatalogTable metadata from a LogicalPlan if the plan is a ResolvedTable. The table can be a non delta table.

  20. def getTablePathOrIdentifier(target: LogicalPlan, cmd: String): (Option[TableIdentifier], Option[String])

    Helper method to extract the table id or path from a LogicalPlan representing a resolved table or path.

    Helper method to extract the table id or path from a LogicalPlan representing a resolved table or path. This calls getDeltaTablePathOrIdentifier if the resolved table is a delta table. For non delta table with identifier, we extract its identifier. For non delta table with path, it expects the path to be wrapped in an ResolvedPathBasedNonDeltaTable and extracts it from there.

  21. def getTouchedFile(basePath: Path, escapedFilePath: String, nameToAddFileMap: Map[String, AddFile]): AddFile

    Find the AddFile record corresponding to the file that was read as part of a delete/update/merge operation.

    Find the AddFile record corresponding to the file that was read as part of a delete/update/merge operation.

    basePath

    The path of the table. Must not be escaped.

    escapedFilePath

    The path to a file that can be either absolute or relative. All special chars in this path must be already escaped by URI standards.

    nameToAddFileMap

    Map generated through generateCandidateFileMap().

  22. def hasBeenExecuted(txn: OptimisticTransaction, sparkSession: SparkSession, options: Option[DeltaOptions] = None): Boolean

    Returns true if there is information in the spark session that indicates that this write has already been successfully written.
