Abstract: A system performs operations that include receiving a database request to access, via a first connection in a connection pool, information stored in a database of the system. The first connection is associated with a physical connection layer and one or more logical connection layers. The physical connection layer points to a first network socket. Additionally, the operations include storing metadata associated with the one or more logical connection layers in a buffer.

Abstract: Techniques are disclosed relating to processing database transactions that include application operations defined by different object relational mapping (ORM) libraries. A transaction router module executing on a computer system receives, from an application, a request for a first database transaction, where the first database transaction includes first and second application operations. The transaction router module then translates the first application operation to one or more first database operations using a first ORM library and the second application operation to one or more second database operations using a second ORM library. Then, the transaction router module determines one or more database connections for the one or more first database operations and the one or more second database operations. Such techniques may advantageously allow applications to switch between using different persistence frameworks and message broker frameworks without substantial adjustments to application code.

Abstract: Responsive to a configuration event, a controller instance generates, according to a current version of a configuration interface between the controller instance and a data instance, a configuration message. The configuration message is obtained, via message service, by remote data instances. The remote data instances attempt to process the configuration message, according to whichever version of the configuration interface the respective data instances are using. Appropriate acknowledgements (based on whether the remote data instances could fully process the configuration message or not) are generated and returned to the controller instance that marks a record for the configuration message as complete for the remote instance or marks the record for the configuration message to be re-sent for the remote instance. After waiting some period of time to allow data instances with out-of-date versions to update, a configuration message update cycle re-sends the message to the appropriate remote data instances.

Abstract: A method includes calculating first connection usage information based on a first number of connections being used in a connection pool over a first time interval and adding a first number of database connections to the connection pool based on determining that the first connection usage information satisfies a first usage threshold. Additionally, the method includes calculating second connection usage information based on a second number of connections being used in the connection pool over a second interval. The second interval has been previously reset responsive to adding the first number of database connections to the connection pool. The method also includes determining whether to adjust the number of database connections in the connection pool based on the second connection usage information.
