A system and computer implemented method for execution of aggregation expressions on a distributed non-relational database system is provided. According to one aspect, an aggregation operation may be provided that permits more complex operations using separate collections. For instance, it may be desirable to create a report from one collection using information grouped according to information stored in another collection. Such a capability may be provided within other conventional database systems, however, in a non-relational database system such as NoSQL, the system is not capable of performing server-side joins, such a capability may not be performed without denormalizing the attributes into each object that references it, or by performing application-level joins which is not efficient and leads to unnecessarily complex code within the application that interfaces with the NoSQL database system.

Aggregation framework system architecture and method

Systems and methods are provided to enable control and placement of data repositories. In some embodiments, the system segments data into zones. A website, for example, may need to segment data according to location. In this example, a zone may be created for North America and another zone may be created for Europe. Data related to operations executed in North America, for example, can be placed in the North America zone and data related to transactions in Europe can be placed in the Europe zone. According to some embodiments, the system may use zones to accommodate a range of deployment scenarios.

Systems and methods for database zone sharding and API integration

A system and computer implemented method for execution of aggregation expressions on a distributed non-relational database system is provided. According to an aspect, an operation is provided to perform the aggregation operation. An indication of at least one foreign collection of documents is accepted. An indication of at least one variable for at least one local field of at least one local collection of documents is accepted. An indication of a pipeline for execution on the at least one local collection of documents and the at least one foreign collection of documents is accepted. An operation comparing the local field of the at least one local collection of documents and the foreign field of the at least one foreign collection of documents is performed. Responsive to the operation, data from the at least one local collection of documents and the at least one foreign collection of documents is aggregated.
