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

Qlik Sense

  • Expensive pricing structure, particularly for enterprise users and large data volumes
  • Performance degradation when working with very large datasets
  • Limited field capacity and strict 10 GB data limit on Starter plan ($300/month)
  • Weak date handling in set analysis compared to other BI tools
  • Poor API usability, particularly for Python scripts and integration workflows

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
Qlik Sense: Does Qlik Sense have a free tier?

Qlik Sense Business (Desktop) is permanently free for individual users for creating personal dashboards, though content cannot be shared. Qlik Cloud Analytics offers a 30-day free trial with full features.

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.
