Abstract: The subject matter described herein provides techniques to ensure that queries of a distributed database observe a consistent read of the database without locking or logging. In this regard, next-write timestamps uniquely identify a set of write transactions whose updates can be observed by reads. By publishing the next-write timestamps from within an extendable time lease and tracking a “safe timestamp,” the database queries can be executed without logging read operations or blocking future write transactions, and clients issuing the queries at the “safe timestamp” observe a consistent view of the database as it exists on or before that timestamp. Aspects of this disclosure also provide for extensions, done cheaply and without the need for logging, to the range of timestamps at which read transactions can be executed.

Abstract: A method includes identifying, by a server module running at a stream data platform, a set of data to be moved to a target data storage tier of the stream data platform, querying, by the server module, service level agreement (SLA) objectives of the target data storage tier, fetching, by the server module, the set of data, selecting, by the server module, a compressor based on the SLA objectives, compressing the set of data using the selected compressor, and storing the set of data in the target data storage tier.

Abstract: An event is determined on a quantum network. A forecasted budget is determined for one or more entangled qubits for communicating at least a portion of one or more communication packets to a recipient interface over the quantum network with a superdense protocol. One or more first qubits that are respectively entangled with one or more second qubits are retrieved. Transmission of the one or more second qubits to the recipient interface is initiated.

Abstract: The present disclosure relates to systems, methods, and non-transitory computer-readable media that generate compressed metric data for digital metrics utilizing a graph-based compression dictionary and time slice compression. For instance, the disclosed systems can utilize a dynamically modifiable graph-based compression dictionary to generate compressed metric label identifiers for metric labels of digital metrics. The graph-based compression dictionary can include nodes and edges corresponding to metric label segments and metric label identifier values, respectively. The disclosed systems can traverse the graph-based compression dictionary using a metric label to determine the corresponding compressed metric label identifier. The disclosed systems can further generate delta compression values for the metric values of the digital metrics. For instance, the disclosed systems can compare metric values within a single time slice (e.g., a time stamp) to generate corresponding delta compression values. In some cases, the disclosed systems further compare the metric values across a time window.

Abstract: A system can identify a group of time-series telemetry data that represents performance metrics of computing devices, wherein the group of time-series telemetry data is represented according to a first number of dimensions. The system can compress the group of time-series telemetry data, wherein the compressed group of time-series telemetry data is represented according to a second number of dimensions that is less than the first number of dimensions, wherein the compressed group of time-series telemetry data is homomorphic. The system can perform a data science operation on the compressed group of time-series telemetry data to produce a first result, wherein the first result is within a predetermined threshold value of a second result of performing the data science operation on the group of time-series telemetry data.

Abstract: An object compression system of a storage service may provide a user-friendly and cost-efficient solution to manage stored objects for users of the storage service. The object compression system may automatically monitor individual objects in an object-based storage system of the storage service. Based on one or more characteristics and additional features of the objects, the object compression system may generate respective determinations whether to compress the individual objects. Responsive to determinations to compress the objects, the object compression system may determine compression algorithms for individual objects. The object compression system may compress the objects according to respective compression algorithms to create compressed files. The object compression system may store the compressed files in a tier different from the objects and delete the objects from the storage service.

Abstract: An apparatus obtains a set of radio data comprising signal strength related values for radio signals transmitted by a transmitter with an association of each signal strength related value with a representation of a geographical location. The apparatus applies a frequency transform to the obtained set of radio data to obtain transform coefficients, each transform coefficient comprising a transform index and an associated transform value. The apparatus selects a subset of transform indices having more significant transform values than the remaining transform indices and compresses the transform indices by encoding each transform index exploiting a probability of occurrence of an index value of a respective transform index. The same or another apparatus decodes the compressed transform indices again for use in position operations.

Abstract: Embodiments of this application disclose example data compression methods and example base stations. One example method includes obtaining, by a base station, identification information of at least one of a data compression device or a data decompression device. A dictionary can then be generated based on the identification information. The dictionary can then be sent to the data compression device and the data decompression device to enable the data compression device and the data decompression device to perform data compression and data transmission based on the dictionary.

Abstract: A system and a method are disclosed for encoding data for transmission, including determining a rank of a first obtained symbol of the plurality of symbols, encoding, at an encoder, the rank of the first symbol, generating a new frequency entry for the first obtained symbol by incrementing an initial histogram frequency entry of the first obtained symbol, determining, based on the new frequency entry of the first obtained symbol, that the rank of the first obtained symbol of the plurality of symbols has a constraint violation with a rank of a first violating symbol in the first encoder LUT, swapping the rank of the first obtained symbol and the rank of the first violating symbol in the first encoder LUT so the constraint violation is resolved, and generating a compressed bit-stream by iteratively applying an encoding function to each symbol of the plurality of symbols.
