 ## Parquet
 
-[Apache Parquet](https://parquet.apache.org/docs/overview/) is a columnar storage format built for Hadoop. It is most efficient without the use of a codec. Positive results, however, can be achieved when it's configured with [S3 Select]({{site.url}}{{site.baseurl}}/data-prepper/pipelines/configuration/sources/s3#using-s3_select-with-the-s3-source).
+[Apache Parquet](https://parquet.apache.org/docs/overview/) is a columnar storage format built for Hadoop. Pipeline authors can use the parquet codec to read Parquet data directly from the S3 object. This will retrieve all data from Parquet. An alternative is to use [S3 Select]({{site.url}}{{site.baseurl}}/data-prepper/pipelines/configuration/sources/s3#using-s3_select-with-the-s3-source) instead of the codec. In this case, [S3 Select]({{site.url}}{{site.baseurl}}/data-prepper/pipelines/configuration/sources/s3#using-s3_select-with-the-s3-source) will parse the Parquet file directly. This can be more efficient if you are filtering or loading a subset of data.

 ## Avro
 
-[Apache Avro] helps streamline streaming data pipelines. It is most efficient when used with the [`avro` codec]({{site.url}}{{site.baseurl}}/data-prepper/pipelines/configuration/sinks/s3#avro-codec) inside an `s3` sink.
