How does Amazon CloudWatch batch logs when streaming to AWS Lambda?

The AWS documentation indicates that multiple log event records are provided to Lambda when streaming logs from CloudWatch.

logEvents
The actual log data, represented as an array of log event records. The "id" property is a unique identifier for every log event.

How does CloudWatch group these logs?

Time? Count? Randomly, from my perspective?

Currently you get one Lambda invocation for every PutLogEvents batch that CloudWatch Logs had received against that log group. However you should probably not rely on that because AWS could always change it (for example batch more, etc).

You can observe this behavior by running the CWL -> Lambda example in the AWS docs.

Some aws services allow you to configure the log intervals such as elastic load balancing. There's a choice between five and sixty minute log intervals. You may not see a specific increment or parameter in the docs because they are configurable based on each service.
