Valentin Kulichenko updated IGNITE-13:
--------------------------------------
Description:
Currently string serialization is done in two steps (see
{{BinaryWriterExImpl#doWriteString}}):
{code}
strArr = BinaryUtils.strToUtf8Bytes(val); // Encode string into byte array.
out.writeByteArray(strArr); // Write byte array into
stream.
{code}
Probably we can write directly into stream while string is encoded, without
intermediate array. This both reduces memory consumption and eliminates array
copy step.
Need to create a micro benchmark first to check if it gives any improvement.
was:Instead of existing logic in readUtf/writeUtf in GridOptimizedMarshaller
try to implement more optimal marshaling when chars are encoded directly to
byte array and unmarshaling when chars are decoded to prepared char array.
> String marshalling can be optimized for binary marshaller
