Catalyst Nosql

How It Works

1. NoSQL vs Data Store — If the user is undecided, apply this matrix:

   	Catalyst Data Store	Catalyst NoSQL
   Schema	Fixed, defined upfront	Flexible, per-item (no uniform structure required)
   Query	ZCQL (SQL-like joins and filters)	Partition key + optional sort key
   Data type	Structured, relational rows	Unstructured/semi-structured, JSON-format
   Priority	ACID compliance, complex queries	High scalability, high write throughput

   Rule: If the user says "ZCQL", "join", "relational", or "fixed schema" — stop and load catalyst-datastore instead.

2. Load references/nosql-basics.md — for SDK operations (insertItems, fetchItem, updateItems, deleteItems, queryTable) and the NoSQLItem builder.

3. Answer — Provide the SDK method call with the correct table name, partition-key attribute, and NoSQLItem construction.

Triggers

Use this skill for: "NoSQL", "document storage", nosql.table, insertItems, fetchItem, updateItems, deleteItems, queryTable, NoSQLItem, "NoSQL vs Data Store", "flexible schema", "Catalyst document database", "schemaless data on Catalyst", or "nested objects in Catalyst".
