Hi, Use these tips for memory planning: https://apacheignite.readme.io/docs/capacity-planning#memory-capacity-planning-example
https://apacheignite.readme.io/docs/capacity-planning#capacity-planning-faq (this has a spreadsheet w/capacity calculator) You could make you cache partitioned, and use compute jobs to run the query simultaneously on multiple machines then reduce the results to have only the top 50. see: https://apacheignite.readme.io/docs/compute-grid https://apacheignite.readme.io/docs/compute-tasks https://apacheignite.readme.io/docs/cache-modes Thanks, Alex -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
