Using Apache Spark for Generating ElasticSearch Indices Offline - Andrej Babolcai, ESET

Sign up or log in to save this to your schedule and see who's attending!

Making historical data available for searching can be a challenge, especially if you have a lot of it. Indexing data to a live cluster can degrade search performance and having a spare cluster where you index your data can be expensive. In this talk we present the approaches we tried and describe an approach to create ElasticSearch indices offline using Apache Spark. When created, these indices are then stored as snapshots in HDFS and can then be restored to a running ElasticSearch cluster. Snapshots in HDFS also work as a backup, ready to restore solution in case of an error.
