Hi pgsql-general mailing list users,
I have a question related to the development of a new index structure.
I am a writing my masters thesis regarding index structures and the
possibility to parallize them.
I already found a post in the archives regarding Open MP, but my
question is somehow different. I am currently not aiming at a production
ready implementation, a prototype is sufficient. I already checked if I
can use a different database, e.g. Apache Derby or MySQL (because they
are already multithreaded), but it is rather complicated to extend them,
I think it is not intended to add new index structures within one of
them. So, long story short, PostgreSQL is optimal for development of a
new index structure and well documented (yeah! really! great! thanks a
lot for that!). I am not aiming for full parallelization, only some
parts of the algorithm regarding build, insert and search are going to
be extended by Open MP. E.g. I want to parallelize searching in multiple
pages by directing some portions to one thread and other portions to
another thread. Do you think that this small amount of parallelization
is possible? Or will there be complications with the used methods by the
buffer manager and so on? What do you think? What are your thoughts?
