Decompress CloudWatch Logs
If you are using Firehose to deliver CloudWatch Logs and want to deliver decompressed data to your Firehose stream destination, use Firehose Data Format Conversion (Parquet, ORC) or Dynamic partitioning. You must enable decompression for your Firehose stream.
You can enable decompression using the AWS Management Console, AWS Command Line Interface or AWS SDKs.
Note
If you enable the decompression feature on a stream, use that stream exclusively for CloudWatch Logs subscriptions filters, and not for Vended Logs. If you enable the decompression feature on a stream that is used to ingest both CloudWatch Logs and Vended Logs, the Vended Logs ingestion to Firehose fails. This decompression feature is only for CloudWatch Logs.
