Native mode support in Firestore Standard and Enterprise editions

With the introduction of Firestore in Native mode support in the Enterprise Edition, both Firestore Core and Pipeline operations are available. The Core operations function differently than in the Standard Edition, because of new indexing rules and a different pricing model.

Feature	Standard edition	Enterprise edition
Supported querying operations	Limited to Firestore Core operations.	Supports Firestore Core and Pipeline operations, and Firestore with MongoDB compatible operations.
Indexing Requirement	All queries require indexes.	Indexes are not required for queries.
Index creation	Automatic indexes are created for single fields. You can manually create composite indexes.	No automatic indexes are created. Indexes need to be manually managed.
Query Performance and Cost	Queries are generally performant due to index requirements.	Query costs and performance can be better than the Standard edition with indexes. You can identify missing indexes using Query Explain and Query Insights. Queries without indexes may risk being non-performant and costly as the dataset grows, requiring monitoring and tuning.
Indexing Overhead Cost	No charge for index entry writes, as indexes are automatic. However, required indexes incur storage costs.	Writing index entries consume write units when an associated document is written (1 write unit per 1 KiB of index entry size). You save on storage costs by not creating index entries for every field.
Billing Model (Reads/Writes/Deletes)	Charged per document read, write, and delete.	Charged for reads and writes in byte tranches. Reads are charged in Read Units (4 KiB tranches). Writes and deletes are merged into Write Units (1 KiB tranches).
Base Pricing (per million) Prices shown are for the us-central1 region.	Reads: $0.03 per 100,000 documents (or $0.30 per million). Writes: $0.09 per 100,000 documents (or $0.90 per million). Deletes: $0.01 per 100,000 documents (or $0.10 per million)	Read Units: $0.05 per 1 million read units. Write Units: $0.26 per 1 million write units. Prices are generally lower if documents are under 4KiB compared to the Standard Read cost.
Real-time Updates Prices shown are for the us-central1 region	Real-time updates are included billed as Reads at $0.03 per 100,000 documents.	Real-time updates have a separate SKU (Real-time update units), charged per 4 KiB tranche. Real-time updates cost $0.30 per million read units.
