We recently released GreenplumPython, a Python library that allows users to interact with Greenplum or PostgreSQL in a Pythonic way. GreenplumPython provides a pandas-like table API that is familiar and intuitive to Python users. GreenplumPython is making it powerful for performing complex analyses such as statistical analysis with
Accelerating Data Processing with PL/Container and GPU: A Powerful Combination PL/Container is an extension of the Greenplum database that provides an easy way to run user-defined functions (UDFs) in Docker containers. With PL/Container, users can package their runtime dependencies into a Docker image and use the UDF in
Author | Brent Doil Introduction Greenplum Database utilizes Multiversion Concurrency Control (MVCC) to maintain data consistency and manage concurrent access to data. Transaction snapshots are used to control what data are visible to a particular SQL statement. When a transaction reads data, the database selects a specific version.
A quick demonstration and examples. TPCH benchmark TPC-H is a benchmark developed to evaluate the performance of large-scale SQL and relational databases by the execution of sets of queries. It has 22 queries against a standard database under controlled conditions. These queries: Give answers to real-world business questions
GreenplumPython is a Python library that scales the Python data experience by building an API. It allows users to process and manipulate tables of billions of rows in Greenplum, using Python, without exporting the data to their local machines. GreenplumPython enables Data Scientists to code in their familiar Pythonic way using
