When should I use Greenplum instead of MySQL?

MPP PostgreSQL-based data warehouse for large-scale analytical workloads with familiar SQL. Teams wanting a PostgreSQL SQL dialect with massively parallel execution for analytical queries. On-premises data warehouse workloads where cloud migration is not yet feasible or desired

When should I use MySQL instead of Greenplum?

Web application databases needing a fast, reliable, and widely-supported open-source RDBMS. LAMP stack and CMS workloads (WordPress, Drupal) with straightforward CRUD operations. Teams familiar with SQL who need a ubiquitous database with massive community and hosting support

What are the main weaknesses of Greenplum?

On-premises-first design; cloud deployment is less seamless than Snowflake or BigQuery. Complex administration: table redistribution, vacuum, and resource queue tuning require expertise. VMware/Broadcom ownership raises concerns about the long-term open-source roadmap

What are the main weaknesses of MySQL?

Fewer advanced SQL features than PostgreSQL: limited window functions, weaker JSON support historically. Oracle ownership raises open-source governance concerns; MariaDB is the common community fork. MyISAM tables (legacy) lack ACID compliance — InnoDB is required for reliable transactions

How Python Data Engineers Use These Tools

Greenplum

Python data engineers use Greenplum's PL/Python extension to run Python transformation logic directly inside the database — writing Python UDFs that execute in parallel across all Greenplum segments. This in-database Python execution avoids moving large datasets out of Greenplum for transformation, keeping all processing co-located with the data.

MySQL

Python data engineers connect to MySQL using `mysql-connector-python` or `PyMySQL`, and use SQLAlchemy with the MySQL dialect for ORM-based pipelines. `pd.read_sql()` pulls query results directly into DataFrames for transformation, and bulk inserts via `executemany()` or LOAD DATA INFILE load processed data back into MySQL tables.
