Subject [jira] Commented: (DERBY-2336) Enable collation based ordering for CHAR data type.
Date Tue, 06 Mar 2007 18:45:24 GMT

Mike Matrigali commented on DERBY-2336:
---------------------------------------

I don't think BasicDatabase is available to the raw store restart recovery code, which needs
the collation information at a very low level 
of the bootstrap recovery loop.  Do you think this should booted to the context stack before
log recovery starts?
So I think we are in a situation where we need the info set in one case for a bottom stack
of the store
that does not have the upper half of the code running and in the storeless case we want it
set when store does not exist.  To me it looks
like either duplicate code or 2 different ways to set the same thing.  


It would be nice if there was a solution that got us incrementally to the "clean design" you
envision - while letting mamta  get some
incremental steps in toward a locale based sort.  I think some of the problems you would like
to see fixed are not involved with sorting
but some of the other datatype interaction with locale which I don't think is part of this
JIRA issue.

> I am breaking down the Parent task DERBY-1478 (Add built in language based ordering and
like processing to Derby) into multiple sub tasks. One of them is to concentrate on enabling
the collation based ordering on (hopefully the simplest of all the character data types) CHAR
data type. This task in itself might need subtasks if it is later found that it can be subdivided
into multiple smaller steps.
