Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

DuckDB

  • A database file accepts one read-write process at a time; other processes must open it read-only and will not see subsequent writes, so DuckDB cannot be the shared database behind several services
  • There is no network protocol, authentication or user management, so exposing it to remote clients means writing and securing your own service around it
  • It is built for scans and aggregations, not for many small transactions, so a workload of high-frequency single-row inserts and updates performs badly compared with SQLite or Postgres
  • Storage files are backwards compatible but not forwards compatible, so a file written by a newer version cannot be read by an older one and every consumer of a shared file must be upgraded together
  • Query memory settings matter: some operations still need to hold significant state, so an under-configured memory limit turns a large join or a high-cardinality aggregation into a spill-heavy query or an out-of-memory failure rather than a slow success

Visual Studio

  • Community edition is free only for individual developers, classroom use, academic research and open-source contribution, not general commercial use
  • Monthly subscriptions are $45 per user per month for Professional and $250 per user per month for Enterprise, and do not include perpetual use rights the way annual Standard subscriptions do
  • A standalone perpetually licensed Visual Studio Professional 2022 costs $499 as a one-time purchase, separate from the subscription tiers

Answered from the vendors’ own pages

DuckDB: Can multiple applications share one DuckDB database?

Not for writing. One process holds the database read-write; others may attach read-only and will not see later writes. Shared multi-writer access needs a different database or a table format with a catalogue.

Visual Studio: What are the pricing differences between subscription types?

Standard subscriptions include access to more benefits, such as Azure dev/test pricing, monthly Azure individual credit, software and download access, services, training, and support. Monthly subscriptions offer flexibility but fewer benefits.

Source
DuckDB: Is it a replacement for a data warehouse?

For single-node analytical workloads up to a few hundred gigabytes it very often is. It is not a replacement when many concurrent users need a shared, governed, always-on service.

Visual Studio: Are discounts available for startups?

There aren't any discounts available to start-ups, however an unlimited number of users within an organization can use Visual Studio Community for specific scenarios like open source work.

Source
DuckDB: Do I have to load data into it?

No. It queries Parquet, CSV, JSON and Arrow in place, including on object storage. Its own storage format is optional and mainly useful when you want indexes, constraints and faster repeated access.

Visual Studio: Who can use Visual Studio Community for free?

In non-enterprise organizations, up to five users can use it. Enterprise organizations (greater than 250 PCs or greater than $1M annual revenue) cannot use it beyond academic/open-source scenarios.

Source
DuckDB: What is MotherDuck's relationship to it?

MotherDuck is a separate company offering a managed and hybrid service built on the DuckDB engine. DuckDB itself remains MIT-licensed and independent of it, with the IP held by the DuckDB Foundation.

Visual Studio: What's the renewal pricing structure?

Enterprise standard renews at $214.09/month (after initial $499.92); Professional at $66.59/month (after $99.99).

Source
DuckDB: Is it suitable for OLTP?

No. It is designed for analytical scans. For transactional workloads with frequent small writes, SQLite or Postgres is the right tool.
