Solr 4.7 – efficient deep paging
Long, long time ago, we described a problem called deep paging. To keep things short – the deeper you want to go in the results, the slower the query will be. This is because Solr needs to prepare the data from the beginning for each query. Until Solr 4.7 there wasn’t a good solution for that problem. With the recently released Solr version, we got a possibility of using so called cursor to drastically improve performance of deep paging.

SolrCloud – What happens when ZooKeeper fails?
One of the questions I tend to get is what happens with SolrCloud cluster when ZooKeeper fails. Of course we are not talking about a single ZooKeeper instance failure, but the whole ensemble not being accessible and so the quorum not present. Because the answer to this question is very easy to verify i decided to make a simple blog post to show what happens when ZooKeeper fails.
