C#: Fully async , PCL, support for Rx • Provide implementation that feels natural to the developer • E.g. Project, build, IDE (where applicable) support • Cover REST API endpoints based on use cases of language • Namespaces • owner: splunk username (defaults to current user) • app: app context (defaults to default app) • sharing: user | app | global | system

Quality/Compliance – What quality gates should I consider? What kind of para-functional characteristics are important to consider? – What heuristics do I use to bless/block a release? – How do I test a data model? – How do I prepare event generation when building/testing an app? – What kind of perf testing should I do and how? – How do I test UI? – How do I security certify my solution? – How do I design to satisfy my retention and compliance policies? – How do I architect to design my availability requirements? – How do I handle geographic disaster recovery / fault tolerance? – How do I properly instrument my solution so that I know what’s happening?

How are current devs creating unique experiences using Splunk – I typically want to see some marketplace success – Cost and pricing are very important to me as a entrepreneur developer. If I am coming in to build a tool that will be commercialized I need to know that the cost structure of Splunk won’t cause my service to be economically unprofitable. What does a typical Splunk application architecture look like? How should I set up my dev environment to be productive with Splunk? How do I integrate Splunk into existing systems? How do I prepare my event generation when developing & testing an app? How do I package an app? deal with app versioning and updates?
