Patent number: 11948025Abstract: Methods, systems, and computer programs are presented for providing stored procedures stored within a database to invoke specified functionality in a cloud data platform. A response to a database query is received at a compute node of a cloud data platform. A java database connectivity (JDBC) instance executing within a sandbox process converts the response into a remote procedure call. The remote procedure call is provided to a stored procedure executing within the sandbox process as the response to the database query.Type: GrantFiled: May 31, 2023Date of Patent: April 2, 2024Assignee: Snowflake Inc.Inventors: Isaac Kunen, Srinath Shankar, Zihan Li, Khushboo Bhatia, Edward Ma

Patent number: 11921733Abstract: Techniques for fetching query result data using result batches includes generating a plurality of result batches based on query result information. The query result information is associated with query result data generated from execution of a query. Each result batch of the plurality of result batches includes a result data retrieval function for a corresponding data portion of a plurality of data portions of the query result data. The plurality of result batches are encoded for distribution to a corresponding plurality of computing nodes. The techniques further include causing retrieving of the plurality of data portions of the query result data by the corresponding plurality of computing nodes based on the result data retrieval function for each of the plurality of data portions.Type: GrantFiled: July 20, 2022Date of Patent: March 5, 2024Assignee: Snowflake Inc.Inventors: Harsha S.

Publication number: 20230359516Abstract: A system for monitoring job execution includes an interface and a processor. The interface is configured to receive an indication to start a cluster processing job. The processor is configured to determine whether processing a data instance associated with the cluster processing job satisfies a watchdog criterion; and in the event that processing the data instance satisfies the watchdog criterion, cause the processing of the data instance to be killed.Type: ApplicationFiled: May 22, 2023Publication date: November 9, 2023Inventors: Alicja Luszczak, Srinath Shankar, Shi Xin

Publication number: 20230336365Abstract: A proxy revocation service provides a reliable service for performing revocation checks. The proxy revocation service queries public certificate authorities for the revocation status of a set of digital certificates and maintains a database of the revocation statuses. The proxy revocation service provides a singular endpoint that is Application Protocol Interface (API) accessible to web clients. Web clients communicate with the proxy revocation service through use of API message to perform revocation checks, rather than communicating with the public certificate authorities using an online certificate status protocol (OCSP). Use of the proxy revocation service provides both a reliable service for performing revocation checks as well as shifts the complexity away from the web clients.Type: ApplicationFiled: June 21, 2023Publication date: October 19, 2023Inventors: Harsh Chaturvedi, Harsha S. Kapre, Srinath Shankar

Publication number: 20220413819Abstract: The subject technology generates, by executing first code in a first programming language, a resilient distributed dataset (RDD). The subject technology generates, by executing the first code in the first programming language, a second RDD based on the generated RDD. The subject technology generates, by executing the first code in the first programming language, a directed acyclic graph (DAG) including the generated RDD and the generated second RDD. The subject technology serializes the DAG. The subject technology generates a database table based on the serialized DAG. The subject technology converts the first code to second code in a second programming language different than the first programming language, and at least one database query in a second format different than the first programming language. The subject technology sends the converted first code and the at least one database query to a database system for execution.Type: ApplicationFiled: August 30, 2022Publication date: December 29, 2022Inventors: Istvan Cseri, Isaac Kunen, Bing Li, Edward Ma, Srinath Shankar

Patent number: 11487771Abstract: Distributed query processing is often performed by a set of nodes that apply MapReduce to a data set and materialize partial results to storage, which are then aggregated to produce the query result. However, this architecture requires a preconfigured set of database nodes; can only fulfill queries that utilize MapReduce processing; and may be slowed down by materializing partial results to storage. Instead, distributed query processing can be achieved by choosing a node for various portions of the query, and generating customized code for the node that only performs the query portion that is allocated to the node. The node executes the code to perform the query portion, and rather than materializing partial results to storage, streams intermediate query results to a next selected node in the distributed query. Nodes selection may be involve matching the details of the query portion with the characteristics and capabilities of the available nodes.Type: GrantFiled: December 7, 2016Date of Patent: November 1, 2022Assignee: Microsoft Technology Licensing, LLCInventors: Willis Lang, Nikhil Teletia, Hideaki Kimura, Alan D.
