Filter class

Builds a new DynamicFrame that contains records from the input DynamicFrame that satisfy a specified predicate function.

Example

We recommend that you use the DynamicFrame.filter() method to filter records in a DynamicFrame. To view a code example, see Example: Use filter to get a filtered selection of fields.

__call__(frame, f, transformation_ctx="", info="", stageThreshold=0, totalThreshold=0))

Returns a new DynamicFrame that is built by selecting records from the input DynamicFrame that satisfy a specified predicate function.

• frame – The source DynamicFrame to apply the specified filter function to (required).

• f – The predicate function to apply to each DynamicRecord in the DynamicFrame. The function must take a DynamicRecord as its argument and return True if the DynamicRecord meets the filter requirements, or False if it doesn't (required).

  A DynamicRecord represents a logical record in a DynamicFrame. It's similar to a row in a Spark DataFrame, except that it is self-describing and can be used for data that doesn't conform to a fixed schema.

• transformation_ctx – A unique string that is used to identify state information (optional).

• info – A string that is associated with errors in the transformation (optional).

• stageThreshold – The maximum number of errors that can occur in the transformation before it errors out (optional). The default is zero.

• totalThreshold – The maximum number of errors that can occur overall before processing errors out (optional). The default is zero.
