Abstract: A server set for a data set may designate a subset of “master” servers that update the data set in order to reduce data version conflicts involving mutually exclusive updates of the data set. Multi-master configurations may fulfill the performance constraints, and the subset of masters may detect and resolve data version conflicts. However, if multiple masters perform conflict resolution for a particular data version conflict, the resolution may produce inefficiency and redundancy (if the masters reach the same outcome) or additional data version conflicts (if the masters reach different outcomes). Instead, among the masters, a merge master may be identified that applies conflict resolution techniques to data version conflicts and forwards the conflict resolution outcome to the other masters for application to the data set to resolve the data version conflict. The other masters may temporarily store updates in a tentative update set until data version conflicts are resolved.

Abstract: Data services for workloads are often provided with a service level agreement specifying various performance guarantees (e.g., latency, availability, scalability, and consistency). Single-master architectures, in which updates to the data set are constrained to a single server, may limit the fulfillment of some performance guarantees. Presented herein are multi-master architectures, in which the server set is partitioned into at least two masters are permitted to update the data set and at least one non-master that is not permitted to update the data set. Non-masters that receive a request to update the data set forward the request to a master server for application to the data set. A master that receives the request applies it to the data set and propagates the update to other master and non-master servers. Conflicting updates may be resolved through a variety of conflict resolution techniques, optionally designating one master server as a conflict resolution server.

Abstract: Aspects of the subject disclosure may include, for example, identifying unselected video content items and preconfiguring playback views for unselected video content items. During a warm-up phase, access to the unselected video content items is precoordinated individually with a separate video player, manifests and license/key are retrieved in anticipation for possible selection for playback. Subsequent selection of one of the unselected video content items initiates playback responsive to selection without repeating any of the preconfiguring, preauthorizing or fetching. Other embodiments are disclosed.

Abstract: Data services are often provided with various performance guarantees. Multi-master architectures, in which multiple master servers are permitted to update a portion of the data set, may facilitate some performance requirements, but may also lead to data version conflicts in which different masters have written different versions of one or more data items. Moreover, conflicts involving different data items may have to be resolved using different conflict resolution techniques. Therefore, various data items of the data set may be associated with a conflict resolution technique selected from a conflict resolution technique set, such as manual conflict resolution; a write order policy, such as last writer wins; a conflict resolution logic; and conflict resolution based on data types. A data version conflict may be resolved by identifying and invoking the selected conflict resolution technique that is associated with the data item, and applying the conflict resolution outcome to the data item.

Abstract: Methods, systems, apparatuses, and computer program products are provided for controlling access to a database. A data processing application may receive, from a user, a request that includes a procedural language code block to access data elements stored in a distributed database. A procedural language code block analyzer may obtain an access control policy that indicates permissions to access the data elements. A control system may determine, based on the access control policy, that access to a restricted portion of the data elements is denied. A reconstruction system may generate a reconstructed code block that allows the user to access data elements that are not restricted, such as by modifying the request to remove the portion that seeks access to the restricted data elements. The reconstruction system may then provide the modified request to the distributed database to receive the data elements to which the user is permitted to access.

Abstract: Distributed transactions are performed over a collection of servers operating as replicas of a data set, where a successful transaction involves meeting a quorum count of replicas that locally commit the transaction. However, performance constraints of data sets and consuming applications may vary (e.g., sensitivity to latency, scalability, and/or consistency), and the performance characteristics of the server set may be partly determined by the transactional commitment and quorum selection. The distributed transaction may be applied by designating the replicas as a set of followers and a leader that initiates the transaction and receives acknowledgments of local commits by each follower. On condition of the acknowledgments meeting a quorum count for the data set according to the performance characteristics of the application, the leader locally commits the transaction and delivers a result.

Abstract: Partitions are enabled to be merged in storage device of distributed database systems. A request to merge a plurality of source partitions into a merged partition is received. Each source partition stores a plurality of data items having corresponding source global identifiers and corresponding source local identifiers. The data items, with corresponding metadata, are appended from the source partitions to an intermediate storage structure in an order defined by the source local identifiers. Target global identifiers and target local identifiers are generated for each of the data items in the intermediate storage structure. The copied data items are flushed from the intermediate storage structure to the merged partition in an order defined by the target global identifiers. The source partitions and intermediate storage structure may then be purged of data, removed, and/or reused for further storage needs.

Abstract: Data sets such as databases are often distributed over a number of servers, where each server stores a subset of records and an index that enables the server to locate the records in response to queries. However, tight coupling of indexing and storage may limit load-balancing, fault recovery, and distribution. Instead, the set of servers may be partitioned into a set of storage servers that store the records and a set of index servers of the index over the records. In a set that is decoupled in this manner, load-balancing may involve provisioning and locating index servers independently of the provisioning and locating of the storage servers in view of the particular sensitivities and tolerances of various applications. Additionally, the index servers may also utilize a data layout that is selected and adapted independent of the data layout of the storage servers and/or the schema of the data stored thereby.
