Re: [rdf4j-dev] SPIN SAIL
|
Hi Håvard,
I can't remember working much on it.
As I am in the office I can't comment in the github
but the variable.
private boolean initializing;
needs to be volatile if you want the check to be
correct JMM wise.
I did not contribute enough to say if this can or can not be skipped.
I think the idea is to make sure you start with a clean state constraint
wise.
Regards,
Jerven

Hi,
Going through the bitbucket Sesame archive, it seems that Dale Visser
started the SPIN implementation.
Jerven Bolleman, Jeen, Mark Hale... also worked on it, so maybe they
could take a look at the PRs
Best regards
Bart

Subject: [rdf4j-dev] SPIN SAIL
Hi,
I’m currently working on performance fixes for the spin sail. It takes
700 ms to initialize on my laptop, and I’ve gotten it down to 150 ms.
Some fixes for slow code and also by skipping validation during
initialization.
I tried to look at the history of the SpinSail to see if I could find
out who wrote it, but I didn’t have much luck.
Does anyone know who wrote it? Or who would know enough about the
implementation to check my PR and answer some questions?
Cheers,
Håvard
