## [](#using-collections)Using Collections
Couchbase Server provides the backing data store for Sync Gateway.
> [!TIP]
> See: [Compatibility Matrix](../product-notes/compatibility.md) for version compatibility information.
Sync Gateway supports scopes and collections ([Default Collections](#7.0@server:learn:data/scopes-and-collections.adoc#default-scope-and-collection), [Named Collections](#7.0@server:learn:data/scopes-and-collections.adoc#naming-for-scopes-and-collections) ).
## [](#practical-limits)Practical Limits
Couchbase Server currently supports up to 1000 scopes and up to 1000 collections per cluster.
Sync Gateway targets the same ceiling for a database's custom scope: up to 1000 custom collections.
