Abstract:
Techniques for querying a Not-Only/Non Structured Query Language (NoSQL) database using Structure Query Language (SQL) commands. A SQL query is received. The SQL query is transformed into one or more non-relational database scans having associated row key ranges. The one or more non-relational database scans are executed in parallel for each row key range. The results from the parallel scans of the non-relational database are combined. The combined results are presented as results of the SQL query.
Abstract:
Techniques and structures for providing a multitenant environment having both a relational database and a non-relational database. A database query is received with at least one server computing device providing a multitenant environment having a relational database system and a non-relational database system, the database query in a format corresponding to the relational database system. The query is parsed with the at least one server computing device to find one or more components of the query directed to data stored in the non-relational database system. One or more components of the query directed to data stored in the non-relational database system are converted to one or more scans of the non-relational database system. Results from the query of the relational database system and results from the one or more scans of the non-relational database system are collected. The results from the query and the results of the one or more scans to a combined result are combined. The combined results are provided to a client entity.
Abstract:
Methods and systems for optimizing queries in a multi-tenant store are described. In one embodiment, such a method includes retrieving data from a multi-tenant database system having a relational data store and a non-relational data store, receiving a request specifying data to be retrieved, retrieving one or more locations of the data to be retrieved, generating a database query based on the request, in which the database query specifies a plurality of data elements to be retrieved, the plurality of data elements including one or more data elements residing within the non-relational data store and one or more other data elements residing within the relational data store, generating an optimized database query having an optimized query syntax that is distinct from a query syntax of the database query, and executing the optimized database query against the multi-tenant database system to retrieve the data.

Abstract:
In accordance with embodiments, there are provided mechanisms and methods for performing transparent object migration across storage tiers. In an embodiment and by way of example, a method for appending data to large data volumes is provided. The method embodiment includes a) setting a CustomEntityOption bit that determines (at object creation time) where the object is stored, either in the relational or the non-relational data store portion, b) loading the CustomEntityOption bit in a cached CustomEntityDefinition, c) showing the CustomEntityOption bit as EntityInfo, and d) allowing custom object definition and Metadata API functionality when the bit is shown.

Abstract:
In accordance with embodiments, there are provided mechanisms and methods for pushing an application update between tenants of a multi-tenant on-demand database service. These mechanisms and methods for pushing an application update between tenants of a multi-tenant on-demand database service can enable tenants providing the application update to force instances of the application utilized by other tenants to be updated. This may allow the tenants providing the application update to ensure that instances of the application utilized by other tenants are updated.
