I know that BLOBs are on the TODO list, but I had an idea.
I think the storage of a BLOB outside of the table is an elegant
solution and keeps table sizes down without the bloat of the stored
object. Granted, if you are searching with a regular expression or
using like or ilike clauses, you're likely to be a little slower but it
shouldn't be by much. More than likely, you won't be searching for
patterns in the BLOB but rather the fields in the table associated with
the BLOB.
Wouldn't it be wonderful if you used the methods you had already
implemented and instead create a behavoir similar to the following.
on an insert take the data that was to be the blob... create your externally "to be referenced" file save the
datato the file store the reference to that file
on an update take the data that was to be the blob... create your externally "to be referenced" file save the
datato the file store the reference to that file delete the old referenced file
on a delete delete the reference to your file delete the external file
I was thinking that the BLOB column type might be a trigger for a macro
that could handle the lo_import, lo_export juggling...
I know it seems overly simplified, but having fought with MySQL and then
trying to wrestle with postgresql and importing,exporting BLOBs, it
seemed there might be a little more room for discussion, although I
doubt this may have added anything to it...
I'd love to see something done with BLOB support during 7.2.x *hint* :)
Besides, if someone could give me some pointers as to where I might be
able to start, I might try to contribute something myself.
