Hi Erick,
Thinking some more about the differences between the two sort orders has
suggested another possibility. We also have a geo spatial field defined in the
index:
echo "$(date) Creating geoLocation field"
curl -X POST -H 'Content-type:application/json' --data-binary '{
"add-field":{
"name":"geoLocation",
"type":"location",
"stored":true,
"indexed":true
}
}' http://localhost:8983/solr/address/schema
One of the differences between the two sort orders is that when the data is
sorted by locality and post code, it means that addresses that are close to
each other will be sorted together as both locality and postcode have
geographic meaning. So when they are indexed, they will be indexed in groups
of addresses that are quite near to each other.
When the data is sorted by DPID, the order is near random as the dpid has no
meaning at all, so the geo location sequence should be random as well.
I don't have time to test this at the moment, as I need to get my project back
on track after chasing this performance issue but it might ring a bell with
somebody.
Regards,
David
