Ironically, we were the last in-person batch that was cut short by COVID, so his comments turned out to be quite helpful.
I've also heard of people storing those links in a database like Snowflake then creating displays on top using Tableau or Looker, to avoid having to build a web app from scratch.
Maybe thermodynamics is a hammer that makes all things seem like nails, but the connections pop up all over the place. Entropy is another highly applicable concept to data systems.
But I’m also generally skeptical of high upvote/comment ratios, because as a long-time HNer too I also want to read things that are genuinely interesting. In this case, I can promise you neither I nor anyone on the team is soliciting upvotes for this post.
On that note, if anyone has any comments about the content itself, happy to discuss further.
The four pillars of data observability: metrics, metadata, lineage, and logs
I wanted to +1 what you said about “organizations that don’t have a proper data warehouse and dedicated BI staff.” At the end of the day, a huge number of companies (maybe even most?) don’t have dedicated data teams but still want to know be alerted about data anomalies. Heck, we at Metaplane even fall into that camp.
Good idea, we actually do have a dbt integration that pulls in lineage and job metadata from your dbt manifests: https://docs.metaplane.dev/docs/dbt. Eventually we want to let you configure Metaplane tests from your dbt YAML.
Pricing is still in flux to be honest. We wanted to start with a price that was approachable for small teams, comparable to other tools in your stack, and could be paid for without going through a whole procurement process. But we’re trying to stay as flexible on pricing as possible!
Datafold is primarily known for their Data Diff regression testing that simulates the result of a PR on your data within a CI/CD workflow. There’s definitely a need for proactively preventing data issues from occurring in the first place, but issues introduced via code are only one subset of potential data quality issues.
Metaplane is focused on catching the symptoms first via continuous monitoring. Regression tests don’t replace the need for observability, and vice-versa.
Atlan is primarily known for their data workspace features that make collaboration easier, like a data dictionary, SQL editor, and governance.
Data collaboration is a huge unsolved problem and data monitoring does play a role there. But Metaplane is focused squarely on the problem of detecting data issues and giving you relevant metadata to prioritize and debug.
We definitely want to explore suggesting data tests based on profiling. Don’t be surprised if you see a fork!
We want every data team to have have observability as soon as they have data in a warehouse, and that means: 1) letting you implement the tool within 10 minutes, without talking to us, 2) providing a free plan and paid plans that make sense for modern data teams, and 3) focusing on being as helpful as we can with as little configuration as possible.
Monte Carlo has built a strong team and has done a great job telling the story of data observability for larger companies. Overall we want to support even the smallest data teams, who we feel are being underserved by other companies in this space.
The reason our customers haven’t required this is because we’ve tried to take security seriously from day one and Metaplane doesn’t store any customer data (just the metadata). We received our SOC2 Type II report, support IP whitelisting, SSH/Reverse SSH tunnels and are always exploring other integration options like AWS’ PrivateLink.
That said, we definitely understand the need to keep even metadata on-prem, so we plan on tackling that later next year.
