Specified by:

setBucketCapacity in interface ChunkedUpdateByOperator

Overrides:

setBucketCapacity in class AbstractStaticUpdateByOperator

Parameters:

capacity - the capacity

getInputColumnName

@NotNull public String getInputColumnName()

Description copied from interface: ChunkedUpdateByOperator

Get the name of the input column this operator depends on.

Returns:

the name of the input column

getOutputColumnNames

@NotNull public String[] getOutputColumnNames()

Description copied from interface: ChunkedUpdateByOperator

Get an array of the output column names.

Returns:

the output column names.

getOutputColumns

@NotNull public Map<String,ColumnSource<?>> getOutputColumns()

Description copied from interface: ChunkedUpdateByOperator

Get a map of outputName to output ColumnSource for this operation.

Returns:

a map of output column name to output column source

makeUpdateContext

@NotNull public ChunkedUpdateByOperator.UpdateContext makeUpdateContext(int chunkSize)

Description copied from interface: ChunkedUpdateByOperator

Make an ChunkedUpdateByOperator.UpdateContext suitable for use with non-bucketed updates.

Parameters:

chunkSize - The expected size of chunks that will be provided during the update,
