Hello All,
After creating the index for all keys:
Index creation:
============
curl -X PUT -H "Content-Type: application/json" \
-H "x-riak-index-day_int: 20110723" \
http://localhost:8098/riak/tagg_dsquery/<key> -d "<data>"
Index Verfication:
===========
curl http://localhost:8098/buckets/tagg_dsquery/index/day_int/20110723
I was able to issue range queries. For dates 07/23 - 07/30 the query runs fine.
Previously, this was not working. I could not go beyond 1 day. But as the data
grows in the later months, i cannot issue a week range. I'm getting the same
"preflist_exhausted" error. The number of records have grown in Oct, Nov, Jan,
Feb etc. How do you deal with the data growth?
Thanks
Mohit

Mohit,
Be aware that key filters are just a thin layer on top of full-bucket key
listings. You'd be better off storing the field you want to filter in a
secondary index, which more efficiently supports range queries (note that only
the LevelDB storage engine currently supports secondary indexes). Barring that,
you could use the special "$key" index for a range query on the key.

My query is doing a range scan. I can only get data for 1 day. For 2 or more

map_js_vm_count - increased to 32,64,128 and 256 but not helping
js_max_vm_mem - increased to 32,64,128,256,512 and 1024.
js_thread_stack - increased to 64,128,256,512,1024 and 2048 (cannot go beyond)

Can anyone help me to debug this issue. My queries cannot go beyond 1 day
Thanks
