Where each one falls short

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

Cassandra

  • No support for joins across tables
  • No ACID transactions across multiple rows
  • Data model must be designed around query patterns upfront, making schema evolution difficult
  • Partition key misconfigurations can cause uneven data distribution and hotspots that degrade performance

Notion

  • Free plan limited to 1,000 blocks for 2+ member workspaces, restricting team usage
  • Free tier only includes trial AI capabilities; full Notion AI requires paid plan
  • Page history limited to 7 days on free plan
  • Per-member pricing increases costs for teams compared to flat-rate competitors
  • Limited automation capabilities compared to dedicated workflow platforms

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
Notion: What are Notion's pricing tiers?

Notion offers four plans: Free ($0/member/month), Plus ($10/member/month), Business ($20/member/month recommended), and Enterprise (custom pricing). All paid plans include Notion AI and identical features with no per-feature charges.

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.
