Formula

Partition count = ceil(table size GB / 10 GB target partition size). Strategy: RANGE for date queries, HASH for key-based.

Domande Frequenti

When should I partition a table?
Partition tables larger than 10 GB, especially when queries filter on a range or key that aligns with partition boundaries.
What is partition pruning?
Partition pruning means the database only scans relevant partitions for a query, ignoring others — dramatically improving performance.
RANGE vs HASH partitioning?
RANGE is ideal for time-series data queried by date. HASH distributes rows evenly, suitable for key-based access patterns.
