A method includes receiving a selection of a first change to a project in a first repository of a plurality of repositories and identifying one or more attributes of the first change to the project. The method further includes identifying a second change to the project in the plurality of repositories in view of the one or more attributes of the first change and performing an action in view of identifying the second change to the project.

Methods and systems are disclosed for dynamically conducting messaging campaigns, responsive to customer events. A set of parameters for a messaging campaign includes an initial schedule for providing a set of messages from a set of data objects. Responsive to a customer event associated with a first customer, an adjusted schedule is generated for providing the set of messages to the first customer. The adjusted schedule differs from the initial schedule in a timing for providing at least a first message, where the first message is scheduled to be provided at an adjusted timing proportionate to a time period between the customer event and a first milestone event. The first message is generated from a first data object and transmitted to the first customer, in accordance with the adjusted schedule.

Presently disclosed are systems and methods for generating customized filtered-and-partitioned market-data feeds. In an embodiment, an output-feed profile is maintained in data storage at a market-data-processing device (MDPD). The output-feed profile specifies a subset of ticker symbols and a ticker-symbol-based feed-partitioning scheme. An input feed of order-book updates to ticker symbols is received at the MDPD from an upstream device. At the MDPD, a customized market-data output feed is generated according to the maintained output-feed profile at least in part by filtering the input feed down to the order-book updates to ticker symbols in the specified subset and partitioning the filtered feed according to the specified ticker-symbol-based feed-partitioning scheme. The customized market-data output feed is transmitted from the MDPD to a downstream device.

A columnar storage method and a query method and system for time series data. The storage method includes: dividing a column of time series data into a plurality of pages, wherein each page stores a part of data points of the column of time series data and the sum of the data points stored in all the pages is all the data points in the column of time series data (S1); and setting two parts, i.e., a page header and a page body, for each page, storing summary index information of all the data points in the page in the page header of the page and storing data value information of all the data points in the page in the page body of the page (S2).

In accordance with an embodiment, described herein are systems and methods for supporting slowly changing dimensions and metadata versioning in a multidimensional database, comprising. A system can comprise a computer that includes one or more microprocessors, and a multidimensional database server executing on the computer, wherein the multidimensional database server supports at least one hierarchical structure of data dimensions. A data dimension can slowly change over time. When such changes occur, metadata associated with the data dimension can be updated. Advantageously, a current snapshot of the data structure can allow searching of previous changes to the slowly changing dimension based upon the metadata.

Systems and methods are disclosed for processing and executing queries in a data intake and query system. An indexing system of the data intake and query system receives data and stores at least a portion of it in buckets, which are then stored in a shared storage system. The indexing system merges multiple buckets to generate merged buckets and uploads the merged buckets to the shared storage system.

Embodiments of the present disclosure describe systems, methods, and computer program products for executing and tuning a machine learning operation within a database. An example method can include receiving a data query referencing an input data set of a database, executing a plurality of machine learning operations to generate, in view of the input data set, a plurality of output data sets each having a respective accuracy value, wherein each of the plurality of machine learning operations is executed by a processing device according to one of a plurality of unique sets of hyperparameters, selecting a first output data set of the plurality of output data sets in view of the accuracy values, and returning the first output data set in response to the data query.

Methods and systems are disclosed for a sequential federated query for information in a residential, commercial, and/or distributed system. A method of processing a sequential federated query for distributed systems may comprise receiving a sequential federated query; deconstructing the sequential federated query into query elements; identifying a Contextual-Characteristic Data Source (CCDS), a Transactional-Unstructured Data Source (TUDS), and a data organization parameter based on the query elements; generating a CCDS result data set from the CCDS based on the data organization parameter; processing the CCDS result data set to develop a TUDS query based on the data organization parameter; generating a TUDS result data set from the TUDS based on the developed TUDS query and the data organization parameter; generating a final sequential federated query data set based on the TUDS result data set and the data organization parameters; processing a formatted sequential federated query data set based on the processing of the final sequential federated query data set and the data organization parameter; and providing the formatted sequential federated query data set to a management system for action.

The invention describes a method for determining a storage location of a database object of a specific version, wherein indexes for each version of the database object are stored in a trie having a root node corresponding to the specific version, the method comprising: determining a trie corresponding to the specific version by accessing the root node of the trie corresponding to the specific version; determining an object identifier of the database object by traversing the trie corresponding to the specific version using a secondary key related to the database object as search key; determining the storage location of the database object by traversing the trie corresponding to the specific version using the determined object identifier as search key.

A database management system for controlling prioritized transactions, comprising: a processor adapted to: receive from a client module a request to write into a database item as part of a high-priority transaction; check a lock status and an injection status of the database item; when the lock status of the database item includes a lock owned by a low-priority transaction and the injection status is not-injected status: change the injection status of the database item to injected status; copy current content of the database item to an undo buffer of the low-priority transaction; and write into a storage engine of the database item.
