Hash Partitioning Implementation
Learn how PostgreSQL hash partitioning spreads rows evenly across a fixed set of partitions using a hash of the key, ideal for balancing load without natural ranges.
When Range and List Do Not Fit
Range partitioning suits dates; list partitioning suits known categories. But what if you just want even distribution with no natural boundaries?
That is where hash partitioning shines.
What Is Hash Partitioning?
Hash partitioning applies a hash function to the partition key and assigns each row to a partition based on the remainder, spreading rows evenly.
