Abstract: In a computer-implemented method for adapting time series database schema of a time series database, time series data ingested into a time series database according to a time series database schema is accessed over a time period, wherein time series data comprises a plurality of dimensions. The time series data of the time period is analyzed to determine a data shape of the time series data of the time period. It is determined whether to adapt the time series database schema based at least in part on the data shape of the time series data of the time period. In some embodiments, the time series database schema is adapted based at least in part on the data shape of the time series data of the time period. Time series data is then ingested into the time series database according to the adapted time series database schema.

Abstract: Electronic devices are disclosed. A first device stores items, parent categories, images, child categories and product information for each item. The first device receives a search image from a second device, determines a parent category and a child category of the search item, identifies a first database from among the databases matching the determined parent category of the search item, when the child category is determined, identifies a subset of the stored items corresponding the first database that match the search image based on at least one feature of the received search image and the determined child category of the received search image, and transmits information on the identified subset of the stored items to the external electronic device. The second device transmits the image of a first item to the first device, and receives a transmission indicating one or more second items matching the transmitted image for display.

Abstract: The present embodiments relate to implementing change data on no-master NoSQL data stores. An optimized node can be identified from a plurality of NoSQL data storage nodes and a specialized node can be connected (e.g., collocated) to the optimized node. The specialized node can maintain change data capture (CDC) data provided by client nodes in a hash map that can be used as a point of truth for coordinating CDC data across the plurality of NoSQL data storage nodes. The plurality of NoSQL data storage nodes can identify and coordinate all read/write data obtained from multiple client devices in a geographically separated large-scale (e.g., planet scale) system to identify change data in a distributed data store. The specialized data can provide read data to devices in the large-scale system to reconcile inconsistencies in change data across nodes in the large-scale system.

Abstract: Embodiments provide systems and methods for learning extract, transform, and load mappings by example. A plurality of features can be extracted from a source schema and a target schema. Example ETL mappings can be provided to a machine learning algorithm that comprise definitions for extracting data from source tables and loading the extracted data into target tables. Using the machine learning algorithm and based on the source schema, target schema, and extracted features, one or more ETL rules can be predicted that define logic for extracting data from the source schema and loading the extracted data into the target schema. Additional ETL mappings can be generated based on the predicted ETL rules, the additional ETL mappings providing additional definitions for extracting data from the source schema and loading the extracted data into the target schema.

Abstract: A method, apparatus, system, and computer program product for processing news items. A computer system receives news items from a network. The computer system identifies relevant news items in the news items based on events in the news items that relate an ability for set of operators to operate a set of properties. The computer system determines a context for the events in the relevant news items. The computer system clusters the relevant news items according to the events in the relevant news items into clusters based on the events such that the relevant news items about the same events are grouped together in the clusters. The same events are determined using the context for the events. The computer system matches the events in the clusters to transactions for the set of properties for the events to form matched transactions. The computer system performs actions for the matched transactions.

Abstract: Methods, systems, and devices supporting determining user and data record relationships based on vector space embeddings are described. Some database systems may receive data record access indications corresponding to data records accessed by users. A database system may generate, based on the data record access indications, user sessions for the users, data record sessions for the data records, or a combination for users and data records. For example, a user session may correspond to a respective user and include a record identifier associated with each data record accessed by the user. The system may generate, in a vector space, vectors from the sessions using an embedding operation, where each vector corresponds to a respective user or data record. The system may determine relationships between the users, data records, or both based on the vectors and may transmit an indication of at least one data record based on the relationships.

Abstract: Methods and systems are described herein for improvements for reducing client-server network traffic. For example, methods and systems allow for the reduction of client-server network traffic by altering search filters based on their respective rank and/or frequencies of being searched with other search filters included in a search query. In this way, users do not have to resubmit queries that are illogical or would return a null set of search results. For example, a first query may be received. A first search may be performed based on the first query. A first search filter may be selected based on a hierarchical tree structure of search filters. A second query may be generated comprising the first search filter and one or more other search filters, wherein the second query comprises fewer search filters than the first query, and a second search may be performed based on the second query.

Abstract: An information management system according to certain aspects configured to implement VM backup and replication operations that reduce the amount of resources and the cost typically associated with such operations. The system can initiate backups of VM data (e.g., persistent data or data written to a virtual disk, such as application data, data saved by an application running on the VM, etc.) and VM memory (e.g., non-persistent data) of a VM. The system can convert the VM data into another format before storage in a secondary storage device occurs. Rather than replicating the VM based on data provided by the production client device, the information management system can initiate VM replication using the backup stored in the secondary storage device. The backup data can be converted into a format associated with the hypervisor that is to run the VM on the target client device before replication to the target client device occurs.

Techniques are provided for pushing down various operators to shard servers.

Abstract: Disclosed are some implementations of systems, apparatus, methods and computer program products for performing data ingestion. A request received from a client device is processed, where the request has a payload including a plurality of data items pertaining to a data object. An identifier associated with the data object is generated. Information including the data items is obtained from the request. The information including the data items is stored in association with the identifier in a first data store, where the first data store is not a relational database. The data items and identifier are obtained from the first data store and stored in a second data store, where the second data store is a relational database. A query including the identifier is processed to obtain the identifier from the query. It is determined whether the identifier obtained from the query is in the first data store.
