Methods and systems are presented for accessing various data values in a record stored in a data store independently from other data values in the record and without taking computationally expensive or storage-intensive procedures such as de-serializing a record based on a primary key. A data service module is provided to access each record in a data store, and generate for the records a table including a map of key-value pairs representing the data values in the records. When the data service module receives a request from an application for accessing a first data value in a first record, the data service module may retrieve a first key-value pair corresponding to the first data value in the first record without de-serializing the record. The data service module then provides a first value of the first key-value pair to the application.

Systems and methods for providing flexible data access

Methods and systems for providing a stateless application framework are presented. The stateless application framework is utilized by different applications for implementing different workflows. Each workflow may be associated with one or more state machine configurations representing the different states within the workflow. Upon receiving an indication of an event from an application, a stateless application module transmits a job request to a data processing engine based on a current state of the event. When a response is received from the data processing engine, the state application module determines whether the state of the event has been updated since transmitting the job request. If it is determined that the state has been updated, the stateless application module is configured to transmit another job request to the data processing engine based on the updated state of the event.

Systems and methods for providing services in a stateless application framework

Methods and systems for providing an external scheduler in a stateless application framework are presented. A first instance of a stateless application transmits a job request to a data processing engine, and submits a message to a messaging queue. The message indicates a task to be performed according to a delayed schedule. The first instance of the stateless application terminates after submitting the message. The messaging queue transmits the message to the stateless application framework according to the delayed schedule. Upon receiving the message, a second instance of the stateless application is instantiated. The second instance of the stateless application performs an action based on the message and terminates.
