Global limits
To optimize query performance and share resources in a fair manner, the following global limits are in place.
Users are responsible for working within the limits. Fauna is intended for operational workloads and attempts to run any queries as quickly as possible.
See the Plan details documentation for the throughput limits of individual Fauna plans.
Constraint | Limit |
---|---|
Document size |
8 MB per document. Document size is the size of document once encoded. Fauna encodes documents in a binary format that’s smaller than raw JSON. |
Query size |
16 MB per query Query size is the size of the HTTP request payload. |
Transaction size |
16 MB per transaction Transaction size is the total size of the transaction’s write. Read-only queries are not subject to this limit. Uses the size of binary-encoded document. |
Compute operations |
12,000 per transaction |
Default query execution time even without a timeout |
2 minutes |
Maximum query execution time even with a timeout |
10 minutes |
Maximum number of collections per database |
1024 |
Concurrent index builds |
500 per account per region group Index builds for collections with more than 128 documents are handled by a background task. The limit prevents an excessive number of indexes that must be built simultaneously. Fauna returns an HTTP 429 error When this limit is exceeded and the transaction is aborted. |
Index entries |
64 KB An index entry includes |
Pagination size range |
1 to 16,000 Minimum and maximum number of paginated values returned by the
|
UDF recursion limit |
User-defined function (UDF) recursion is limited to a depth of 2048 calls. |
Protective service limit |
Fauna returns HTTP status code 429 if a query causes read, write, or compute ops to generate excessive traffic that exceeds protective service limits. See Plan throughput limits. |
