NYCPHP Meetup

[Jerry Kapron]

Well, I do not have any code yet, but I can explain what I'm trying to do.
I want to load the most accessed (read from) db tables as arrays into a
shared memory segment at startup. Has anyone done or heard of anything like
that done? I'm not talking about heap tables but using php's shared memory
functions (shm_*) instead.  I realize that querying those arrays will not
be as easy as quering a sql database but i'll come up with some kind of
interface function(s).  I should probably mention I'm talking about a
*very*  busy site with thousands of select queries/sec. Also, I heard that
it's a good idea to rebuild the shm segment often (cron job) due to memory
leaks in PHP when using shm_* functions. Was that ever fixed?  Is there
anything I should consider before starting to implement this approach.
cheers,
-jerry
