Next Steps

Measure time spend on index, flush, refresh, merge, query, etc. (TD - done)
Take hot threads snapshots under read+write, read-only, write-only (TD - done)
Adjust refresh time to 10s (from 1s) and see how load changes (TD)
Measure time of a rolling restart doing disable_flush and disable_recovery (TD)
Specify routing on query -- make it choose same node for each shard each time (MD)
GC new generation size (TD)
Warmers

measure before/after of client query time with and without warmers (MD)

TL;DR

My team is looking for a site reliability engineer passionate about observability and reliability.

We are the team responsible for Platform and Site Reliability at Apptio, building our Kubernetes platform in AWS (EC2), including a bunch of leading-edge technology services around it to reduce the friction for our development teams.

In a typical day on this role, you will interact with Golang, Jsonnet, Kubernetes, Puppet, GitLab CI, Docker, Confluence, Jira, Slack, and AWS.

Don't worry if you don't know all these names/acronyms; we are not expecting you to, technology moves very fast these days.
