It is a bit different from a normal plugin because only one blobcontainer plugin can be loaded at a time. This is because the plugin replaces blob data being inserted or updated with a kind of blob URL, storing the actual BLOB data some where else. I rethought the idea of making this a generic 'filter' plugin and decided it was not worth it. It would just add complexity and make maintenance more difficult while adding a feature of dubious value. On a related topic does anybody have an opinion on if it would be a good idea to keep small blobs in the table itself while storing larger BLOBs somewhere else. This would mean the column would have a mixture of BLOB URLS and BLOBS. This is allowed in MySQL with the PBMS engine now. When the BLOB column is accessed using the PBMS API it can handle this transparently for the user. The definition of what a small blob is would be a plugin parameter. Right now you can end up replacing a BLOB with a BLOB URL that is bigger than the BLOB.
