Kafka Connect SMT to perform regex transform on field content

This SMT supports regex transform of a Key or Value field

Properties:

Name	Description	Type	Default	Importance
name	Field name	String	``	High
regex	Filed content regex pattern	String	``	High
replacement	Replacement string to use if field content has matched to pattern	String	``	High
default	Replacement string to use if regex doesn't match	String	``	High

Regex pattern is internally compiled

Example on how to add to your connector:

transforms=regexrewrite
transforms.regexrewrite.type=com.github.ostridm.kafka.connect.transforms.RegexRewrite$Value
transforms.regexrewrite.name="hash"
transforms.regexrewrite.name="([0-9a-f]{40}|)"
transforms.regexrewrite.replacement="{\"hash\":\"$1\", \"algorithm\":\"SHA-1\"}}"
transforms.regexrewrite.default="{\"hash\":\"\", \"algorithm\":\"SHA-1\"}}"
