Abstract: A system performs masking of data stored in a database. The system receives change logs from a source database and masks the change logs to generate masked change logs. The system stores the masked change logs in a pre-buffer. If the system determines that the set of masked change logs stored in the pre-buffer corresponds to a complete transaction, the system determines whether any conflicts exist between masked change logs stored in the pre-buffer and masked change logs stored in a main buffer. If the system identifies conflicts, the system applies the masked change logs stored in the main buffer to a masked replica database. This causes the system to move masked change logs corresponding to a complete transaction from the pre-buffer to the main buffer.

Abstract: An improved content indexing (CI) system is disclosed herein. For example, the improved CI system may include a distributed architecture of client computing devices, media agents, a single backup and CI database, and a pool of servers. After a file backup occurs, the backup and CI database may include file metadata indices and other information associated with backed up files. Servers in the pool of servers may, in parallel, query the backup and CI database for a list of files assigned to the respective server that have not been content indexed. The servers may then request a media agent to restore the assigned files from secondary storage and provide the restored files to the servers. The servers may then content index the received restored files. Once the content indexing is complete, the servers can send the content index information to the backup and CI database for storage.

Abstract: Techniques are described handling database transaction in a manner that is efficient and flexible. In some embodiments, a system receives, through a page of a user interface, a first request to change at least a first data object. The system generates, based on the first request, a first atomic transaction to modify the first data object in a database. Before the first atomic database transaction has committed to the database, the system receives, through the page of the user interface, a second request to change at least a second data object. The system generates, based on the second request, a second atomic transaction to modify the second object in the database. The system may execute the second atomic transaction independently of the first atomic transaction.

Abstract: Data units of a dataset may be compressed by clustering the data units into clusters, selecting a reference unit for each unit cluster, and compressing data units of each unit cluster using the reference unit of the unit cluster as a dictionary. The computational efficiency of the clustering algorithm may be improved by not applying it to data units themselves, but rather to hash values of the data units, where the hash values have a much smaller size than the data units. The hash function may be a locality-sensitive hash (LSH) function. The reference unit of a cluster may be determined in any of a variety of ways, for example, by selecting a centroid or exemplar of the cluster. Clusters, including their references values, may be indexed in a cluster index (e.g., a Faiss index), which may be searched to assign future added or modified data units to clusters.

Abstract: A method, apparatus, and computer program product for communicating real-time updates among web clients. A structured data object is composed from a set of data nodes according to a domain specific language in response to requesting access to a data within a human resources database. The structured data object is interpreted within a context of a record ID/form to identify content for the web page and to determine whether real-time updates are enabled for the web page. Interpreting the structured data object, displays the form with the content. An event queue is created and a connection to the server hub is established when real-time updates are enabled. In response to receiving an update event in the event queue, a notification of the update event is displayed when the update event matches the record ID/form that a first user has opened.
