JSONB
A binary JSON data type in PostgreSQL that supports efficient querying and GIN indexing.
Timeline (last 90 days)
For task metadata storage, use JSONB if queries are mainly single-record reads and writes, and use normalized tables if they are mainly graph traversal and aggregate statistics.
JSONB is Postgres's binary JSON storage type, supporting indexing, nested queries, and partial updates, but using it loses some column-level constraints and type checking.
