Scaling DB Access for Billions of Queries Per Day @PayPal
As microservices scale and proliferate, they add increasing load on databases in terms of connections and resource usage. Open sourced in the Go programming language, Hera (High Efficiency Reliable Access to data stores) scales thousands of PayPal’s applications with connection multiplexing, read-write split, and sharding. This talk covers various approaches taken over the years to handle a large growth in application connections and OLTP database utilization. Beyond pure connection and query scaling, Hera has functionality for better manageability. Automatic SQL eviction and DBA maintenance control help to more easily operate hundreds of databases.
