Sebastian Nagel commented on NUTCH-2924:
----------------------------------------
Hi [~markus17], see NUTCH-2455 and [PR
#254|https://github.com/apache/nutch/pull/254]: it includes a scalable solution
reading the HostDb only once but not into memory. Unfortunately, the PR wasn't
merged - there are some things still to do.
