Hi, I am using Solr 4.10.2. I have 200K documents sitting on Solr cluster (it has 3 nodes), and let me first state that I am new Solr. I want to retrieve all documents from Sold (essentially just one field from each document).
What is the best way of fetching this much data without overloading Solr cluster? Approach I tried: I tried using the following API (running every minute) to fetch a batch of 1000 documents every minute. On Each run, I initialize start with the new index i.e adding 1000. http://SOLR_HOST/solr/abc/select?q=*:*&fq=&start=1&rows=1000&fl=url&wt=csv&csv.header=false&hl=false However, with the above approach, I have two issues: 1. Solr cluster gets overloaded i.e it slows down 2. I am not sure if start=X&rows=1000 would give me the correct results (changing rows=2 or rows=4 gives me totally different results, which is why I am not confident if I will get the correct results). Thanks Obaid
