I see some behavior at the moment when I'm flushing and would like to know if I
can change that.
One main thread is inserting, when it flushes, it blocks.
During that time my main thread is blocking. Instead of blocking, Could it
spawn another thread to do that ?
Basically, would like to have one main thread adding document to my index, if
a flushing needs to occur, spawn another threads but it should never lock the
main threads. Is it possible ?
Is the only solution is to have many threads indexing the data ?
In that case Is it true to say ONLY one of them will be busy while the other is
flushing ? (I do understand that if my flushing is taking two much time, they
will both flush... :-))
Thank you!
Simon
