Firehose supports database as a source in all AWS Regions except China Regions, AWS GovCloud (US) Regions, and Asia Pacific (Malaysia). This feature is in preview and is subject to change. Do not use it for your production workloads.
Send CloudWatch Logs to Firehose
CloudWatch Logs events can be sent to Firehose using CloudWatch subscription filters. For more information, see Subscription filters with Amazon Data Firehose.
CloudWatch Logs events are sent to Firehose in compressed gzip format. If you want to deliver decompressed log events to Firehose destinations, you can use the decompression feature in Firehose to automatically decompress CloudWatch Logs.
Important
Currently, Firehose does not support the delivery of CloudWatch Logs to Amazon OpenSearch Service destination because Amazon CloudWatch combines multiple log events into one Firehose record and Amazon OpenSearch Service cannot accept multiple log events in one record. As an alternative, you can consider Using subscription filter for Amazon OpenSearch Service in CloudWatch Logs.
