Can we fix your Solr or Elasticsearch system in a single day?

Here at Flax, we're often called in to take a look at existing Apache Solr or Elasticsearch search applications, to suggest improvements, tune-ups or enhancements. It's impossible for us to know ahead of time what we might find - out-of-date versions of the software, slow performance on either (or both) the indexing or search side of the application ...Continue reading

Can you make a contribution to Apache Solr core development?

Working with Hadoop, Kafka, Samza and the wider Big Data ecosystem

We've been working on a number of projects recently involving open source software often quoted as 'Big Data' solutions - here's a quick overview of them. The grandfather of them all of course is Apache Hadoop, now not so much a single project as an ecosystem including storage and processing for potentially huge amounts of data, spread across clusters of machines. Interestingly Hadoop was originally created by Doug Cutting, who also wrot...Continue reading
