Interesting write-up. I'd love to see stats on how the new database is performing. Have they reduced it from running on 45 4xlarge instances? Do backups still take a day? Was it a good financial decision?
- barkanido 9y agoFinancially it was a good decision. The current cluster is a lot less than the original one, and traffic + data have grown since. we currently maintain 2 clusters of 5 i3.4xlarge machines. That's a total of 10 machines and is a lot cheaper of what we had before. The DB is performing great. It is flash based and 99.98% of the queries have <1ms latency. Each XDR end holds around 3.1B records, with a replication factor of 2. midterm load is around 3 (very low) and we are doing around 190K reads p/s plus 37K write p/s at pick load.
