---------------------------------------
Summary: Creating a String during deserialization could be
optimized
Key: GEODE-6579
URL: https://issues.apache.org/jira/browse/GEODE-6579
Project: Geode
Issue Type: Improvement
Components: serialization
Reporter: Darrel Schneider
When creating a string during deserialization from data that we know is in the
ASCII character set (each character can be represented by one byte) we
currently read all the bytes into a temporary byte array and then create a
String instance by giving it that byte array. The String constructor has to
create its own char array and then copy all the bytes into it. After that the
byte array is garbage.
We could instead directly create a char array, fill it by reading each byte
from the DataInput into it and then using reflection to directly set this char
array as the value field of the String instance we just created (as an empty
String). This prevents an extra copy of the data and reduces garbage creation.
