------------------------------------
Summary: FilterRoutingInfo.FilterInfo.toData does unneeded copying
Key: GEODE-2161
URL: https://issues.apache.org/jira/browse/GEODE-2161
Project: Geode
Issue Type: Bug
Reporter: xiaojian zhou
This is #52614
FilterInfo.toData (that was being optimized for murex) does this:
// create a hdos
// write a bunch of stuff to it
byte[] myData = hdos.toByteArray();
DataSerializer.writeByteArray(myData, out);
he toByteArray allocates a new byte array and copies all the data in the hdos
to it.
Then writeByteArray writes it all to "out".
We can do this instead:
if (out instanceof HeapDataOutputStream) {
out.writeAsSerializedByteArray(hdos);
} else {
.. do it the old way
}
