Greenplum alternatives
Greenplum alternatives, compared by how much you must rewrite.
Alternatives fall into two groups: platforms that descend from Greenplum, and platforms that do the same job differently. The first group costs less to move to. The second may fit your future better.
The short answer
The main Greenplum alternatives are Apache Cloudberry and EDB WarehousePG, which descend from Greenplum, plus Snowflake and Databricks, which are cloud platforms with a different architecture. The closer the platform is to Greenplum, the less SQL and ETL you rewrite. Choose by workload, skills, and where your data is heading.
Framing
How do you choose a Greenplum alternative?
This is a how-to-choose guide, not a ranking. Ace8 does not resell any of these platforms, so the comparison is on fit. Five questions decide it: how much Greenplum-specific code you have, whether you must stay on-premises, whether open source is a requirement, what your team already knows, and what the platform will cost at your data volume.
Comparison
How do the options compare?
| Option | Relation to Greenplum | Runs where | Rewrite effort | Fit |
|---|---|---|---|---|
| Apache Cloudberry | Open-source fork of the Greenplum codebase | On-premises or your own cloud | Lowest | Teams that want Greenplum behavior with open source |
| EDB WarehousePG | Commercial distribution derived from Greenplum, from EDB | On-premises or cloud, with vendor support | Low | Teams that want a vendor-supported fork |
| Other Postgres-based MPP | Distributed Postgres designs, such as extension-based or sharded | Varies | Medium to high | Smaller warehouses, hybrid workloads |
| Snowflake | Different architecture, separate storage and compute | Cloud service | Medium to high | Cloud-first, variable demand, many consumers |
| Databricks | Lakehouse on open table formats | Cloud service | Medium to high | Teams combining warehouse, data science and streaming |
Closest fit
What about Cloudberry and WarehousePG?
Apache Cloudberry is a project at the Apache Software Foundation that continues from the Greenplum source. It keeps the MPP design, distribution keys, append-optimized storage and much of the tooling. EDB WarehousePG is a supported distribution from EDB that is also derived from Greenplum. Both keep most Greenplum SQL working, which is the main reason to choose them. Details of the move are on Greenplum to Cloudberry migration.
Check version lineage before you commit. Which Greenplum major version a fork tracks decides how much of your existing code works unchanged. Ask each project directly for the current compatibility statement.
Different architecture
When do Snowflake or Databricks make more sense?
Greenplum ties compute and storage to a cluster you size in advance. Snowflake and Databricks separate them, so you scale compute up and down and pay for use. That fits workloads with spiky demand and many separate consumers. It fits poorly when a job is steady, heavy and runs all day, where a fixed cluster can cost less.
The cost of the move is code. Distribution keys, append-optimized table choices, external table loaders and Greenplum functions have no direct counterpart. Expect to redesign loads and rewrite some SQL. See data warehouse modernization for the architecture side.
Checklist
What should you check before choosing?
- Count external tables, gpload jobs and PL/pgSQL functions. They set the rewrite size.
- List every tool that connects: BI, ETL, notebooks, drivers.
- Measure the biggest and slowest queries, not the average ones.
- Decide whether data may leave your network.
- Price each option at your data volume for three years, not one.
- Run a proof on your own heaviest workload before deciding.
The other option
Is staying on Greenplum an alternative?
Yes. If the decision is not clear, read the stay, upgrade or exit guide. AceMQ supports Greenplum and can price the stay path; see AceMQ's Greenplum pages.
After go-live
Keep it running after cutover.
For least rewriting, Apache Cloudberry or EDB WarehousePG. For a cloud-first design, Snowflake or Databricks. The best one depends on your workload and constraints.
An open-source MPP database at the Apache Software Foundation, forked from Greenplum and built on PostgreSQL.
Largely, since it comes from the Greenplum code. Compatibility depends on your Greenplum version and which features you use, so test your own workload.
It depends on usage. Steady heavy workloads can be cheaper on a fixed cluster. Spiky or shared workloads often cost less on Snowflake. Model it with your numbers.
Plain PostgreSQL can replace a small or mid-size warehouse. For large parallel scans you need an MPP design, which is why Cloudberry and similar forks exist.
No. Ace8 migrates to the platform that fits. AceMQ supports Greenplum if you stay.
