Show HN: MetricFlow – open-source metric framework https://ift.tt/qoJihzs
Show HN: MetricFlow – open-source metric framework Hi HN community, I’m Nick, co-founder/CEO of Transform.co. I’m thrilled to share MetricFlow, an open-source metric creation framework: https://ift.tt/GCZOLe2 MetricFlow strives to make what has historically been an extremely repetitive process, writing SQL queries on core normalized data models, much more DRY. MetricFlow consolidates the definitions for joins, aggregations, filters, etc., and programmatically generates SQL to construct data marts. You can think of it like LookML, but more powerful and ergonomic (and open source!). The project has three components: 1. MetricFlow Spec: The specification encapsulates metric logic in a more reusable set of abstractions: data_sources, measures, dimensions, identifiers, metrics, and materializations. 2. DataFlow Planner: The Query Planner is a generalized SQL constructor. We take in data sources (ideally normalized data models) and generate a graph of data transformations (a flow, if you will) – joins, aggregations, filters, etc. We take that graph and render it down to db-specific SQL while optimizing it for performance and legibility. 3. MetricFlow Interfaces: The CLI and Python SDK rely on the flexibility of the Spec and Planner to build just about any query you could ask for on top of your data warehouse. These components enable novel features that other semantic layers struggle to support today: - MetricFlow enables the user to traverse the entire graph of a company’s data warehouse without confining their analysis to pre-built data models (dbt), Explores (in Looker), or Cubes (in lots of tools). - The Metric abstraction allows the construction of complex metrics that traverse the graph described above to rely on multiple data sources. We support several common metric types today, and adding more is a critical part of the open-source roadmap. - The Materialization abstraction allows users to define and then programmatically generate data marts that rely on a single DRY expression of the metrics and dimensions. MetricFlow is open source( https://ift.tt/GCZOLe2 ) and distributed through pypi (`pip install metricflow`). You can set up (`mf setup`) a set of sample configs and try out a tutorial (`mf tutorial). The docs are all here( https://ift.tt/6xhPMSW ). We’d love contributions on GitHub. We’re adding new Issues to share our roadmap in the coming days, but feel free to open your own. We’re also opening up a Slack community( https://ift.tt/w8i9JB3 ) to talk about the project and, more generally, metric tooling. Let us know what you think – we’ll be here answering any questions! https://ift.tt/GCZOLe2 April 7, 2022 at 03:42AM

Show HN: I built a tool to aggregate your investments and follow other investors Hi HN! Over the past year, we’ve been building Wealthly ( https://wealthly.com ), a tool to help you aggregate all your investments, and a community of investors who are sharing their portfolios and knowledge. I started working on this idea because I had two personal frustrations: 1. I had a few different brokerage accounts, some retirement accounts, and a little crypto all in different places. It was hard to get a glance of everything I had. I tried all the products in the market, and they all had various issues (poor data quality, constant disconnect, didn’t support options, etc) 2. I learned a great deal about investing from other people online, but I always wanted to see where people actually put their money. I needed the transparency because it gave me a sense of comfort and trust We’ve slowly built up a small group of users who have connected close to $18M of live assets. We’re hoping that the HN community will find a tool and a community like this useful! I think whenever a product like this shows up, the number one thing people get most concerned with is always security and are you scraping brokerages for data. Unfortunately we don’t have a magic bullet around this issue in the US. We use the brokerages’ official OAuth APIs whenever we can, and resort to scraping when we’re forced to with no other solutions. To address the security and privacy concerns people have, we are also thinking about open sourcing our connectors, and creating a desktop app where all your data is stored locally instead of in the cloud. We haven’t opened up sign ups yet, but you can join with this invite link: https://ift.tt/LTiJRSb . Would love to hear any feedback! This is my personal portfolio: https://ift.tt/x83zUWn https://ift.tt/I9CqY1n April 7, 2022 at 01:32AM
