Can I customize partitioning in Kinesis Firehose before delivering to S3?

No. You cannot 'partition' based upon event content.

Some options are:

  • Send to separate Firehose streams
  • Send to a Kinesis Data Stream (instead of Firehose) and write your own custom Lambda function to process and save the data (See: AWS Developer Forums: Athena and Kinesis Firehose)
  • Use Kinesis Analytics to process the message and 'direct' it to different Firehose streams

If you are going to use the output with Amazon Athena or Amazon EMR, you could also consider converting it into Parquet format, which has much better performance. This would require post-processing of the data in S3 as a batch rather than converting the data as it arrives in a stream.
