[Investigation] Offline "Filter and Pattern Syntax"

[cchan9528]

Overview

Cloudwatch uses its own "Filter and Pattern Syntax" (https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/FilterAndPatternSyntax.html) that is not simply regex. Therefore, the plugin must accommodate this special syntax to some extent.

Ask

Figure out a way to support the Cloudwatch "Filter and Pattern Syntax".

Questions

• Should this be a separate open source library?
• Is this a blocker?
• How much of the filter and pattern syntax should be supported? How much does regular regex cover?

3 possiblities ? Regex not included? Maybe it's a security risk of some sort to have regex....

The new project should probably have

• implementation match AWS doc requirements
• unit tests match the AWS doc examples
• integration tests be online/networked to use AWS CLI pattern tester
