Handle data overrun of DDMWriter buffer more efficiently
--------------------------------------------------------
Key: DERBY-1372
URL: http://issues.apache.org/jira/browse/DERBY-1372
Project: Derby
Type: Improvement
Components: Network Server, Performance
Versions: 10.1.2.1
Reporter: Kathey Marsden
Priority: Minor
Currently if data writing overruns DDMWriter's 32K buffer,
Network server will allocate a twice as big buffer and copy the
data. This could be made more efficient.
One possibility is to keep a shared pool of buffers and chain them. This might
also help with general scalability of network server.
When this is fixed, the code in writeQRYDTA to guestimate if we
have enough remaining room in the block can be removed.
