Stratio Crossdata: a SQL-like language for streaming queries

This is achieved thanks to its generic architecture and the definition of a custom SQL-like language. Our language augments the classical SQL data manipulation language in order to add support for streaming queries. From the point of view of the user, a common logical view of the existing catalogs and datastores is presented independently of which cluster or technology stores a particular table.

Supporting multiple architectures imposes two main challenges: how to normalize the access to the datastores, and how to cope with datastore limitations. In order to be able to access multiple datastore technologies Crossdata defines a common unifying interface containing a basic set of operations that a datastore may support. New connectors can be easily added to Crossdata to increase its connectivity
