GitHub has over 21TB of source code. Applications consistently pour through this data and emit logs and events. 1TB of data by breakfast maybe? In reality, we're not pushing logs to datadog, just metrics and event tags. Our level of cardinality, however, requires a lot of horsepower on the backend. Our attempted Prometheus transition was just not cost effective when attempting to view large sets of data over a large-ish period of time. Combined with the heavy lift of integration (we depended heavily on dogstatsd) it just didn't seem efficient to move to Prometheus, support the infrastructure required, all while migrating to microsoft's inhouse product.
