hey bserial, I'm part of the team working on Dagster.

While there are many things we're working on, there are 3 goals that got me excited about working on this system:

1. Local development: most modern workflow orchestration systems don't have a good local development story. We want to provide a seamless end-to-end dev experience from your laptop to CI to dev to prod for authoring data workflows.

2. Complexity: the Airflow deployments I've worked on or otherwise encountered have hundreds of DAGs and thousands of tasks scheduled on an hourly or daily cadence. We aim to provide abstractions to better support managing and wrangling that complexity.

3. Testability: Most modern data platforms are poorly tested. Many orchestration systems, like Airflow, tend to hardcode deployment concerns the business logic, e.g. EmrAddStepsOperator. With Dagster, we aim to separate the business logic from environmental concerns to make it easy to swap out an external resource implementation for a mock, dev version, etc.

Hope that makes sense!

We use Pulumi to manage both our GCP and AWS resources, and we really like it.

You might consider using Terraform directly if you want something more mature.

We use DynamoDB quite a bit at Thumbtack. Our biggest issue is backups - just wrote a short note about our experiences with DynamoDB here: https://medium.com/@natekupp/dynamodb-and-backups-16dba0dbcd...

The original Science paper is here: http://science.sciencemag.org/content/356/6342/1046.full

The section "Relativistic deflections by foreground stars" walks through the math which enables this, which I found really interesting.

Have you considered just applying through the jobs pages of the larger tech companies? Apple, Google, Facebook, LinkedIn are all on the peninsula and more accessible than startups in SF.

We're also doing this at Thumbtack. We run all of our Spark jobs in job-scoped Cloud Dataproc clusters. We wrote a custom Airflow operator which launches a cluster, schedules a job on that cluster, and shuts down the cluster upon job completion. Since Google can bring up Spark clusters in < 90s and bills minutely, this works really well for us, simplifying our infrastructure and eliminating resource contention issues.

I'm constantly surprised by how much work Amazon expects its customers to do themselves. The work that Segment has done here should be a service provided by AWS directly, continuously updating cost data in a Redshift database without any customer work required.

We just migrated our data infrastructure to GCP. One of the big motivators was experiences like this with AWS. We've got near-realtime GCP cost dashboards in BigQuery, and the only meaningful work on our end to make that happen was writing the SQL queries.

Airflow is very similar to Luigi; we've been using in in production to schedule all of our workflows for ~4 months now and it's worked out really well for us.

> I find people either really, really hate the design, or like it.

A sign you're doing things right :) great work. Looking forward to seeing more.

I'm very surprised there are no responses to this article suggesting looking for relevant publications in the literature.

Often, difficult problems are not unique, and it can be very helpful to take a look at what has been published to see if anyone has already devised an elegant solution for the class of problems you are currently trying to solve.

It'd be really great if you guys had an implementation of Friedman's Multivariate Adaptive Regression Splines[1]. For me, this is the only R package left for which I don't have a Python alternative.

Not my area of expertise, but I believe most research today is on microfluidics, introducing microchannels into 3D interconnect layers alongside the TSVs to cool the device. For example, http://deepaksekar.weebly.com/uploads/1/9/8/6/1986457/3d_mic...
