When we started Gravwell years ago, we knew it was going to be a significant undertaking requiring some serious tooling under the hood. Building a custom data lake and analytics platform from scratch that can scale to hundreds of TB/day ain't easy. We chose Go for a lot of reasons and that choice has paid dividends in terms of what we've been able to accomplish in so short a time.

This post is about our tooling, and some of the lessons we have learned along the way in managing a large Go codebase. A few weeks ago Gravwell made the switch to Go modules on both our open source github repositories and our internal repo. Let's talk about about our planned workflow going forward and a few caveats we've run into.

Amazon’s Kinesis Streams service provides a powerful way to aggregate data (logs, etc.) from a large number of sources and feed that data into multiple data consumers. For instance, a large enterprise might use one Kinesis stream to gather log data from their cloud infrastructure and another stream to aggregate sales data from the web services running on that infrastructure. Once the data is in the stream, it remains available for up to a day (or optionally longer) for any number of applications to read it back for processing and analysis. This is particularly useful to customers that want to deploy and destroy virtual machines on a whim; data is stored in the stream, rather than the ephemeral VMs.
