Summary

Elasticsearch is a powerful tool for storing and analyzing data, but when using it for logs and other time oriented information it can become problematic to keep all of your history. Chaos Search was started to make it easy for you to keep all of your data and make it usable in S3, so that you can have the best of both worlds. In this episode the CTO, Thomas Hazel, and VP of Product, Pete Cheslock, describe how they have built a platform to let you keep all of your history, save money, and reduce your operational overhead. They also explain some of the types of data that you can use with Chaos Search, how to load it into S3, and when you might want to choose it over Amazon Athena for our serverless data analysis.

Interview

Introduction How did you get involved in the area of data management? Can you start by explaining what you have built at Chaos Search and the problems that you are trying to solve with it?

What types of data are you focused on supporting? What are the challenges inherent to scaling an elasticsearch infrastructure to large volumes of log or metric data?

Is there any need for an Elasticsearch cluster in addition to Chaos Search? For someone who is using Chaos Search, what mechanisms/formats would they use for loading their data into S3? What are the benefits of implementing the Elasticsearch API on top of your data in S3 as opposed to using systems such as Presto or Drill to interact with the same information via SQL? Given that the S3 API has become a de facto standard for many other object storage platforms, what would be involved in running Chaos Search on data stored outside of AWS? What mechanisms do you use to allow for such drastic space savings of indexed data in S3 versus in an Elasticsearch cluster? What is the system architecture that you have built to allow for querying terabytes of data in S3?

What are the biggest contributors to query latency and what have you done to mitigate them?

What are the options for access control when running queries against the data stored in S3? What are some of the most interesting or unexpected uses of Chaos Search and access to large amounts of historical log information that you have seen? What are your plans for the future of Chaos Search?

Summary

The way that you store your data can have a huge impact on the ways that it can be practically used. For a substantial number of use cases, the optimal format for storing and querying that information is as a graph, however databases architected around that use case have historically been difficult to use at scale or for serving fast, distributed queries. In this episode Manish Jain explains how DGraph is overcoming those limitations, how the project got started, and how you can start using it today. He also discusses the various cases where a graph storage layer is beneficial, and when you would be better off using something else. In addition he talks about the challenges of building a distributed, consistent database and the tradeoffs that were made to make DGraph a reality.
