Hello All,
If I am not mistaken the process of locking the Index by different
objects like IndexReader or Indexwriter, theoratically only one Thread
can access the index at a time.
When we do search on the index it creates a commit lock so the other
thread does not modify the index, so other thread waits until the
previosu therads release the lock, is it right?
So in this case I should say index accessed one by one not parallel?
Its just my speculation, please don't get me wrong.
Because I try to share the same index by 6 instances and since the lock
for 5 instances are disabled and only once instance can modify the
index, at this case I achive the parallel read of the index. Only
disadvantage is that when the index modified then I get
FileNotFoundException, ao I do some kind of respawn the search again.
If I implement the lock mechanism in the DB using the custom locking
then I am afraid the index performance will be reduced but the only
advantage is that I can avoid FNFE.
With Regards,
supriya
