- || Documentation backend work || Jeff Levitt (I would nominate Andrew or Scott Hutinger
to replace me though, I think they might be a better fit, if they so desired || There exists
a need for improvement to the PDF generation and the overall presentation of our documentation
in general. || DocFixes || 1 ||

- || SQL PSM  Support || Dan Debrunner || Proposal to support functions and procedures written
in SQL by compiling them to server-side JDBC Java byte code and then executing them using
the existing Java routine support. Functionality could then be extended to SQL/PSM with control
statements || SqlPsmSupport ||  ||

- || Add support for shared code || David Van Couvering || Currently it is not possible to
safely share code between Derby jar files.  This proposal would be to identify and implement
a mechanism for sharing code that does not cause issues with compatibility in a mixed version
environment || An initial attempt to define the ground rules for this can be found at SharedComponentVersioningGuidelines||

Grøvlen?|| Derby currently uses a clock algorithm to determine which pages to replace in
its page cache. We have indications that this algorithm is far from optimal for some type
of loads.  Many other database systems use variants of an LRU-based algorithm, i.e. the pages
that are least recently used will be candidates for replacement. || ["LRUCache"] ||

  ||Network client Quality Improvements|| Kathey Marsden|| Derby introduced the network client
JDBC driver with its 10.1.1.0 release.  There is still important quality work pending to match
the robustness of our embedded Driver.  This is a great opportunity to learn about JDBC, XA,
and DRDA protocol and become active in the Apache Derby development community.||NetworkClientQualityImprovements||??||
