open files problem" that can occur on linux systems (if you have a
large number of collections)?
IMHO, you can create your collections with custom configuration which
specifies maximum number of descriptors allowed (See
CONFIG_DESCRIPTORS_MAX =
"max-descriptors") instead of relying on the default
(DEFAULT_DESCRIPTORS_MAX = 16).
Yes I know but what if at one time a collection "A" gets a high load and
would need 16 and sometimes later a collection "B" gets this high load
while "A" is not used. In that case I would prefer that the open
descriptors for "A" get closed if they are not used for a (configurable)
amount of time
There is a problem with such reasoning, it is: "what if *all* collections get
high load at the same time?". In this situation, you can't borrow descriptor
from another collection, and you can't block and wait - this might cause
deadlocks. Any ideas? :)
and that is what I implemented (though it's still being
tested and not yet configurable).
Ok.
