Dear colleagues,
Any idea how to adjust the processing capacity of the Riak JavaScript in
the Map / Reduce process to avoid the error [preflist_exhausted] ?
Checking the user posts, I also see a similar error report sent at 29/05
by Mr. Sati, Hohit.
The Map/Reduce and search capability are interesting features, mainly when
it comes to the analysis of unstructured data.
Thanks in advance for your hints.
Regards,
Claude

Subject: Riak / Map, Reduce - error [preflist_exhausted]
Sent by: riak-users-boun...@lists.basho.com
Dear colleagues,
The map reduce process via JavaScript shows an error [preflist_exhausted]
when doing larger queries on unstructured data. Up to to 500 keys, the
queries run OK, but when going to 5000 keys in a bucket the error starts
to apear. My version is kv 1.1.2 (git). I would like to use the
Javascript procedures as it delivers more powerful pattern search behavior
compared to the Lucene like search syntax function.
I've already tried the following adjustments in the app.config file
{map_js_vm_count, 24 },
{reduce_js_vm_count, 18 },
{js_max_vm_mem, 48},
Any hint where to start the tuning to avoid this error?
Regards,
Claude
