Answered from the vendors’ own pages

Cassandra: Does Cassandra support joins between tables?

No. Cassandra does not support joins or foreign keys. The data model requires denormalization, meaning data must be duplicated across tables to support different query patterns.

Source
SavvyCal: Does SavvyCal have a free plan?

Yes. SavvyCal offers a free plan with one active scheduling link and one calendar connection for basic individual use.

Source
Cassandra: Does Cassandra offer ACID transactions?

No. Cassandra provides only row-level atomicity and isolation, not full ACID transactions across multiple rows or tables. It uses lightweight transactions via Paxos for per-row compare-and-set operations.

Source
SavvyCal: What makes SavvyCal different from Calendly?

SavvyCal uniquely allows recipients to see their own calendar overlaid with your availability, making it easier to find matching times without browsing a list of open slots.

Source
Cassandra: What programming languages can connect to Cassandra?

Cassandra supports official drivers for multiple languages including Python, Java, Node.js, and Go, allowing applications to communicate via the native Cassandra protocol.

Source
SavvyCal: What calendar platforms does SavvyCal integrate with?

SavvyCal integrates with iCloud Calendar, Outlook, Zoom, and Microsoft Teams to prevent double-bookings and sync availability.

Source
Cassandra: Can I deploy Cassandra in the cloud?

Yes. Cassandra can run on any cloud platform (AWS, Google Cloud, Azure) via Docker, virtual machines, or managed services like DataStax Astra DB, which provides a fully managed DBaaS option.

Source
Cassandra: Does Cassandra have a free option?

The open source Apache Cassandra is free. DataStax also offers Astra DB with a free tier providing up to 25GB storage and 25 million read/write operations per month.
