The short version

  • Only Cassandra has a free tier, so it costs nothing to try first.
  • Each has a real cost: ADP no pricing is published; every quote is custom and driven by employee count and which services are taken; Cassandra no support for joins across tables
  • They diverge on capability: ADP covers Payroll, Cassandra covers Linear Scalability.

Where each one falls short

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

ADP

  • No pricing is published; every quote is custom and driven by employee count and which services are taken
  • Split into three separate products by company size, RUN for 1 to 49 employees, Workforce Now for 50 and above, and Lyric HCM for enterprise, so growing across a threshold means changing product rather than plan

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

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
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
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
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.
