Abstract: Systems and methods described herein provide heterogeneous access to tenant databases. A delegator intermediary to clients and tenant database receives a request from a client to perform a database related action. The request identifies a query type and tenant identifier. The tenant databases include a first tenant database of a first database type and a second tenant database of a second type. The delegator identifies a tenant database using the tenant identifier from the request. The delegator determines a database type corresponding to the identified tenant database. The delegator selects, from a plurality of drivers corresponding to respective database types, a driver based on a database type for the identified tenant database. The delegator establishes a database connection using the selected driver between the delegator and identified tenant database. The delegator uses the database connection for performing the database related action from the request.

Abstract: There is provided a method and system with an improved bitmap access control method of file virtualization for large files in sandbox. The process divides a large file to pieces clusters by fixed byte counts, building a mapping relationship between logical view of sandboxed file and physical shadow file on disk. Thus, there is no need to copy an entire file when a file is modified and waste the user's disk storage.

Abstract: A global and local row count limit associated with a limit query are received by a stop operator of a first execution node among a set of execution nodes that are assigned to process the limit query. Local distributed row count data is generated based on a local row count corresponding to a number of rows output by the first execution node in processing the query. Based on determining the local row count satisfies the local limit, the first execution node buffers rows produced in processing the query. The local distributed row count data is updated based on remote distributed row count data received from a second execution node. A stopping condition is detected based on determining the global limit is satisfied based on updated local distributed row count data and query processing by the first execution node based on detecting the stopping condition.

Abstract: Aspects of the disclosure relate to processing systems for performing distributed data storage and query processing. A computing platform may receive a query requesting source data collection and may route the query to logical sub-chamber objects.

The computing platform may route, to additional logical sub-chamber objects, the modified query and the identified source data collection. The computing platform may determine that the request associated with the source data collection has been satisfied in its entirety and may assemble a dataset corresponding to the source data collection in its entirety. The computing platform may send the dataset corresponding to the source data collection.
