Summary: camel-core - Optimize DefaultHeaderFilterStrategy
filtering
Key: CAMEL-16202
URL: https://issues.apache.org/jira/browse/CAMEL-16202
Project: Camel
Issue Type: Improvement
Components: camel-core
Reporter: Claus Ibsen
Fix For: 3.9.0
Attachments: Screenshot 2021-02-13 at 17.07.36.png
When using a default pattern, we know what its ahead of time, and can do a
quicker check, eg as its about keys starting with Camel or org.apache.camel.
Otherwise the regexp patterm matcher may allocate excessive objects.
if (pattern != null && pattern.matcher(headerName).matches()) {
return filterOnMatch;
}
