ZSON: Efficient JSONB Compression for PostgreSQL
ZSON is a PostgreSQL extension designed for seamless and transparent compression of JSONB data. By utilizing a shared dictionary of frequently occurring strings within JSONB documents, ZSON can significantly reduce disk space usage and improve transaction processing speeds, making it ideal for applications with substantial JSONB data workloads.
Features
Transparent compression of JSONB data, reducing storage requirements by up to 50%
Performance enhancement with potential transaction processing speed increases of around 10%
Dynamic learning of data patterns to optimize compression through the zson_learn procedure
Ability to migrate to new dictionaries as JSONB schemas evolve, ensuring continued efficiency
Easy integration with existing PostgreSQL setups, enhancing JSONB handling without major configuration changes
Comprehensive diagnostics tools such as zson_info to monitor dictionary usage and performance
