sknop opened a new pull request #9950:
URL: https://github.com/apache/kafka/pull/9950
Cast SMT transformation for bytes -> string.
Without this fix, the conversion becomes
ByteBuffer.toString(), which always gives one of these useless results:
"java.nio.HeapByteBuffer[pos=0 lim=4 cap=4]"
"[B@5ec0a365" (for byte array)
With this change, the byte array is converted into a hex string of the
byte buffer content, for example
"FEDCBA9876543210"
Completed with test case and successfully tried out in a
real database conversion.
