You’re joining tables, resolving status types, cross-referencing data manually with other systems, and by the end of it all you ask yourself why? Things got hairy. We wanted a scalable service that was near real-time, 2.

CLI tools The Cassandra systems were EC2 virtual machine (Xen) instances. Since instances of both CentOS and Ubuntu were running in parallel, I could collect flame graphs at the same time (same time-of-day traffic mix) and compare them side by side. This is how Java flame graphs looked at the time.

Nonetheless, we found a number of limitations that could not satisfy our requirements e.g. stalling the processing of log events until a dump is complete, missing ability to trigger dumps on demand, or implementations that block write traffic by using table locks. Blocking write traffic by locking tables. Writing events to any output.
