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.
SourceDoodle: Does Doodle offer a free plan?
Yes. Doodle's free plan includes one active group poll, one booking page, and one 1:1 meeting, limited to 10 slots per poll with ads displayed. Premium plans start at $15/month.
SourceCassandra: 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.
SourceDoodle: What are Doodle's pricing plans?
Professional plan costs $15/month (or $132/year). Team plan costs $19.95/user/month (or $8.95/user/month billed annually) with a two-seat minimum.
SourceCassandra: 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.
SourceDoodle: Does Doodle integrate with calendar apps?
Yes. Doodle integrates with Google Calendar and Outlook Calendar to prevent double-bookings. Slack integration allows poll creation and sharing directly in Slack channels.
SourceCassandra: 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.
SourceCassandra: 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.
