Publication number: 20210112115Abstract: A distributed event processing system is disclosed that receives continuous data streams, registers a continuous query against the data streams, and continuously executes the query as new data appears in the streams. In certain embodiments, the distributed event processing system deploys and executes applications (e.g., event processing applications) by distributing the execution of the application on a cluster of machines within the system. In certain embodiments, the system provides users with the ability to specify logical rules in an application. The system processes the logical rules by generating a DAG of transformations representing the logical rules and converts the DAG of transformations into a logical rules Resilient Distributed Dataset (RDD) DAG of transformations. The system processes events in an event batch against the RDD DAG of transformations to generate a set of output results for the user.Type: ApplicationFiled: November 17, 2020Publication date: April 15, 2021Applicant: Oracle International CorporationInventors: Hoyong Park, Gyorgy Geiszter, Dmitrii Andreevich Strizhikozin, Péter Gordos, Prabhu Thukkaram, Vitaly Bychkov, Dmitrii Markovskii

Publication number: 20210103592Abstract: An event processing system for distributing a continuous query, and processing events in an event stream, is disclosed. The system can synchronize timestamps across all partitions by adding a heartbeat propagator component propagating a heartbeat signal for silent partitions. The system can further include a timestamp tracker component that tracks the maximum observed timestamp across all partitions for each batch, and sends this to each partition. The system can distribute partitions of the events to the worker nodes, and instruct a heartbeat propagator component to generate a heartbeat for a first worker node corresponding to an event in a different partition. The system receives outputs from the worker nodes and combines these into a single result corresponding to a continuous query. The system can further implement a timestamp tracker to select a highest timestamp value of a previous batch, and send the value to the worker nodes.Type: ApplicationFiled: December 16, 2020Publication date: April 8, 2021Applicant: Oracle International CorporationInventors: Sandeep Bishnoi, Hoyong Park, Subhrajyoti Choudhury, Yathish Gatty, Devendra Jain, Santosh Kumar, Prabhu Thukkaram

In some examples, an input source comprising information that identifies a plurality of events may be identified. Additionally, in some examples, an adapter for ingesting the information of the input source may be implemented. At least one additional component for modifying the adapter may be received. The adapter may be modified by implementing the at least one additional component with a transport component and a mapper component as part of ingesting the information.

Patent number: 10831619Abstract: Techniques for providing fault-tolerant stream processing. An exemplary technique includes writing primary output events to a primary target and secondary output events to one or more secondary targets, where the primary output events are written by a primary server and the secondary output events are written by one or more secondary servers. The technique further includes receiving an election of a new primary server from a synchronization system upon a failure of the primary server, where the new primary server is elected from the one or more secondary servers. The technique further includes determining, by the new primary server, the primary output events that failed to be written to the primary target because of the failure of the primary server, and writing, by the new primary server, the failed primary output events to the primary target using the secondary output events read from the one or more secondary targets.Type: GrantFiled: September 28, 2018Date of Patent: November 10, 2020Assignee: Oracle International CorporationInventors: Hoyong Park, Sandeep Bishnoi, Prabhu Thukkaram

Patent number: 10740196Abstract: An event processing system is disclosed that processes events of an event stream and performs the recovery of events during system failure. The recovery of events is performed by generating output sequence numbers for each deterministic output event generated by the event processing system. In an embodiment, the event processing system determines a current output sequence number of a most recently transmitted output event in a output stream of events, a last output sequence number of an output event corresponding to a most recently processed batch of input events and determines a set of one or more output events of the output stream to be transmitted based on the current sequence number and the last output sequence number. The event processing system then transmits the output events related to the application.Type: GrantFiled: February 19, 2019Date of Patent: August 11, 2020Assignee: Oracle International CorporationInventors: Hoyong Park, Sandeep Bishnoi, Unmesh Anil Deshmukh, Prabhu Thukkaram
