Abstract: Technologies are disclosed for merging and vending partial database schemas. A schema compiler exposes a network services application programming interface (API) for merging partial database schemas for a database. Prior to merging partial database schemas, the schema compiler can determine whether namespace conflicts exist between the partial database schemas. If no namespace conflicts exist between the partial database schemas, the schema compiler can merge the partial database schemas to create a merged database schema. The merged database schema can then be provided to a database service that provides the database. The API can also include methods for retrieving partial database schemas from the merged database schema, updating or replacing database schemas in the merged database schema, and deleting partial database schemas from the merged database schema.

Abstract: A database includes a plurality of partitions with respective partition dates. A query is received for data from a view of the database, the query containing a filtering parameter for retrieval of the data.
