Attachment Perf Improvement
---------------------------
Key: AXIS2-2946
URL: https://issues.apache.org/jira/browse/AXIS2-2946
Project: Axis 2.0 (Axis2)
Issue Type: Improvement
Components: kernel
Reporter: Rich Scheuerle
Assignee: Rich Scheuerle
I am working on a performance improvement improvement reading attachments.
Currently the Axiom Attachments code reads bytes until it surpasses the file
threshold. If the file threshold is high (i.e. 100M) this causes a very large
buffer to be created....even if the attachment is stored on file.
The improvement is to use the content-length of the message as a heuristic to
determine if the attachments should be flushed to file.
This improves performance and memory footprint.
The first part of the change is to add an Axiom Attachment constructor to axiom
that accepts a content-length parameter. If the content-length is set, then
the the heuristic is used.
The second part of the change is to add code to the Axis2 kernel builder to
pass in the content-length.
