Investigating ROXIE Queries - Krishna Turlaparthi, Director Softare Engineering, LexisNexis Risk Solutions

This talk will discuss ROXIE architecture and how to understand more about ROXIE query performance by looking at various fields in the ROXIE logs and some new stats that have recently been added. An example of collecting and analyzing stats for a completed query will be provided. Some interesting information will be presented about our own experiences with containers and an important ROXIE optimization about graph dependencies and how that affects when activities can start.
