Hi Everyone,
I am currently doing my master thesis wherein I have to work with Jena SDB
using mySQL as a backend store.
You have to work with it?
I have around 25 million triples to load
which has taken more than 5 days to load in windows platform,
I admire your persistence! How are you loading it? What type of machine is this
running on?
Sounds like it's seriously memory starved to me. [1] suggests increasing
innodb_buffer_pool_size,
which determines the db memory buffer. The default is very small.
It's also faster to load the data and then build the indexes.

Are you using the sdb bulk loader or loading via your own code?
What format is the data in?
