In PostgreSQL, when there are many inserts and rare queries, it is preferable to use the JSON format instead of 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 beneficial for frequent write operations. If queries are rare and do not require complex content-based queries, JSON will be more efficient.
Summary:
- Frequent inserts + rare queries → JSON
- Frequent queries with filtering → JSONB
