florin-akermann opened a new pull request #11456:
URL: https://github.com/apache/kafka/pull/11456
Adding: --property parse.headers=true to cmdl enabled header parsing.
Just like with the ConsoleConsumer, tif headers and/or key enabled then the
order is "headers key value".
The separator for the header and headerKey are configurabel and default to
the same as in the ConsoleConsumer.
In short,
Default parsing pattern when:
parse.headers=true and parse.key=true:
"h1:v1,h2...\tkey\tvalue"
parse.headers=false and parse.key=true:
"key\tvalue"
parse.headers=true and parse.key=false:
"h1:v1,h2...\tvalue"
Testing strategy:
The testing is constrained to testing LineMessageReader as this is the only
affected class.
Different combinations of parse.headers=true|false and parse.key=true|false
are tested.
Different string patterns are tested. Including input that does not fit the
expected Pattern.
LineMessageReaderTest.testLineReader suggests that the change is backward
compatible.
