Abstract: Initially, a database schema is parsed and a table tree structure is created delineating the relationships between data that are identified in the schema. In addition to accomodating relationships between main tables of data, the table tree structure also accomodates possible side tables of data, and possible circular references between tables, should such be encountered when parsing the schema. Subsequently, a migration mechanism consumes the generated table tree structure and iteratively migrates data in accordance therewith. Individual layers of the table tree structure are migrated consecutively with referenced layers being migrated prior to referencing layers. Circular links are accommodated through temporary null values, and side tables are accommodated during migration of the referencing main table. The iterative process provides completeness and fault tolerance/failure recovery.

Abstract: A method includes generating a task using a plurality of logical statements embedded in a database, the plurality of logical statements corresponding to a data modification. Database data is ingested into a staging table that is configured within the database. The task is executed based on applying the data modification to a first set of partitions storing the database data and generating a second set of partitions. The second set of partitions store modified data corresponding to the database data. A stream of committed transactions is advanced at least in part by adding an entry into the stream. The entry corresponds to committed transactions performed on the first set of partitions during the data modification. A data processing task is scheduled for execution on the modified data based on the advancing of the stream offset.

Abstract: A data stream conversion service may crawl a non-relational database to determined database attributes that characterize the data structure of the non-relational database. The data stream conversion service may evaluate the one or more attributes of the non-relational database to generate a schema for a relational database, wherein the schema maps the non-relational database attributes to respective fields of a relational database. The data stream conversion service may generate a relational database using the determined schema and replicate a data stream for the non-relational database to the relational database.

Abstract: A system performs delivery of a data pipeline on a cloud platform. The system receives a specification of the data pipeline that is split into smaller specifications of data pipeline units. The system identifies a target cloud platform and generates a deployment package for each data pipeline unit for the target cloud platform.

Abstract: Technology described herein assigns a reliability score to web content, such as a web site or portion of a website. In one aspect, an output of the technology is a high reliability score and a low reliability score for a web content. The high reliability score represents conformance to high reliability sites, while the low reliability score represents conformance to low reliability sites. The high reliability score may be generated by first identifying high reliability online content within a compressed web graph. In a first iteration, the high reliability score of the seeds is used to score online content that is linked to the seed sites. At a high level, the more links that originate from high reliability sources, the higher the reliability score for the linked content. The low reliability score is similar, but uses outgoing links to low reliability sites instead of incoming links from high reliability sites.

Abstract: Systems and methods for generating and maintaining data objects may include server(s) for receiving first and second data points associated with entities and root relationships between entities. The first data points may have entity values which are defined according to an entity type and one or more attributes of the entity. The second data points may have relationship values which are defined according to a root relationship type and one or more attributes of the root relationship. The server(s) may generate entity base layer data objects and relationship base layer data objects for the first and second data points. The server(s) may provide access to base layer data objects for identifying contextual relationships between respective base layer data objects. The contextual relationships may be identified by applying conditional rules received from a computing device to data corresponding to the entity values and/or the relationship values.

Abstract: A distributed storage system includes table controllers collectively storing partitions of a logical table having multiple rows. For each of the partitions, a corresponding table controller stores a subset of the rows of the logical table across individual pages. A management controller updates a schema of the logical table from a first to a second schema definition by, for each of the partitions, sending an update command indicating the second schema definition to the corresponding table controller. The first table controller corresponds to a first partition that includes a first subset of the rows. The first table controller, prior to receiving the update command, includes an identifier of the first schema definition within each page of data for the first subset. Subsequent to receiving the update command, the first table controller, when writing each new page of data for the first subset, includes an identifier of the second schema definition.

Abstract: Implementations relate to determining whether and/or how to implement a user request to prevent a particular search result from being provided in response to a search query. Some of those implementations grant or deny the request based on processing of the particular search result, the search query, and/or account information for a user submitting the user request. For example, some implementations process such information utilizing a classifier in determining whether to automatically deny the request, automatically approve the request, or to provide the request for manual review. Some additional or alternative implementations at least selectively automatically expand (or suggest for automatic expansion) an approval of a request to search result(s) and/or to one or more search queries that are not specified in the request.
