# Filter class
Filter

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

## Example
Example

We recommend that you use the [`DynamicFrame.filter()`](aws-glue-api-crawler-pyspark-extensions-dynamic-frame.md#aws-glue-api-crawler-pyspark-extensions-dynamic-frame-filter) method to filter records in a `DynamicFrame`. To view a code example, see [Example: Use filter to get a filtered selection of fields](aws-glue-api-crawler-pyspark-extensions-dynamic-frame.md#pyspark-filter-example).

## \$1\$1call\$1\$1(frame, f, transformation\$1ctx="", info="", stageThreshold=0, totalThreshold=0))
\$1\$1call\$1\$1

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.
