Robert Reynolds commented on SOLR-2667:
---------------------------------------
I haven't seen any discussion of the luke problem since back in August
(comments by Ryan and David, with one follow-up by Stefan). I've run into this
recently and wanted to add some data about just how horrible this problem is.
I timed how long it took to complete loading of the "Statistics" panel, which
evidently requires results from luke, which seems to read the entire index to
provide them. I also looked a bit at the CPU and I/O behavior of the nodes
while this operation was going on.
At the time, my nodes had from 13 million to 23.5 million documents each. The
operation took from 28 minutes to 46 minutes. During this time, significant
CPU was consumed on the node; I wasn't careful in collecting this data but my
recollection is 25%-50% utilization. There was significant I/O the entire
time, apparently due to reading the whole index. Furthermore, navigating away
from the page does not halt the operation.
As things stand, if someone navigates to this web page they kick off an
operation that will signficantly affect performance on my nodes for half an
hour to an hour. Are there plans to implement any of the triage ideas floated
by Ryan/David?
