Concerning URI length: I am with Christophe here: half the world
restricts URIs to 255 characters and it should be enough for "normal"
applications. As almost every request accesses the URI table it might be
a performance problem using blobs. So I would propose to leave this for
the default implementation.


OK, for me - for now. Thought it looks like the same old
jdbc-mysql-schema-mistake: BLOBs for uri - but pk(255) .. Silly!

Do not quite understand. What is silly here?



I've attached an updated mysql-schema, how I think it should look like.


The delta is:
- tinyint for Booleans,
- dropped indexes (because primary and unique are indexes)
- Single or first unique became primary

Now, the bad news: I hadn't got any time testing this.
So, if you check this and it doesn't work - dump it.
But if it do work for you, I wouldn't be surprised it do it quite a bit
faster (insert and delete with less indexes).

What do you say, Christophe? If you agree I will make the modifications...
