Basic ( mapping = None , * , ignore_unknown_fields = False , ** kwargs )
Basic tier is a cost-effective and low compute tier suitable for the
following cases:
Experimenting with RagManagedDb.
Small data size.
Latency insensitive workload.
Only using RAG Engine with external vector DBs.
NOTE: This is the default tier under Spanner mode if not explicitly
chosen.
