When processing a large number of inserts and rare queries, which data storage format is preferable in PostgreSQL: JSON or JSONB?

In PostgreSQL, for a large number of inserts and infrequent queries, it is preferable to use the JSON format rather than JSONB.

The reason is that JSONB is a binary format that is indexed and optimized for fast queries and filtering, but inserts and updates in JSONB are more time-consuming due to parsing and indexing.

JSON is stored as text and inserted faster, which is advantageous for frequent write operations. If queries are infrequent and do not require complex content-based queries, JSON will be more efficient.

In summary:

• Frequent inserts + infrequent queries → JSON
• Frequent queries with filtering → JSONB
