Methods for updating reference count and shared objects in a concurrent system
A method for referencing and updating objects in a shared resource environment. A reference counter counts is incremented for every use of an object subtype in a session and decremented for every release of an object subtype in a session. A session counter is incremented upon the first instance of fetching an object type into a session cache and decremented upon having no instances of the object type in use in the session. When both the reference counter and the session counter are zero, the object type may be removed from the cache. When the object type needs to be updated, it is cloned into a local cache, and changes are made on the local copy. The global cache is then locked to all other users, the original object type is detached, and the cloned object type is swapped into the global cache, after which the global cache in unlocked. |

Real time fault tolerant stateful featurization
Certain aspects of the present disclosure provide techniques for operation of a feature management platform. A feature management platform is an end-to-end platform developed to manage the full lifecycle of data features. For example, to create a stateful feature, the feature management platform can receive a processing artifact from a computing device. The processing artifact defines the stateful feature, including the data source to retrieve event data from, when to retrieve the event data, the type of transform to apply, etc. Based on the processing artifact, the feature management system generates a processing job (e.g., the API defines a pipeline), which when initiated generates a vector that encapsulates the stateful feature. The vector is transmitted to the computing device that locally hosts a model, which generates a prediction that is transmitted to the feature management platform. Subsequently, the predication and stateful feature can be transmitted to other computing devices. |

Consistency checks between database systems
Techniques and solutions are described for determining whether an update to be sent to a production database system from a quality database system will provide consistent table relationships if applied at the production database system. These consistency checks can be carried out without transmitting entire table records from the quality system to the production system, which can reduce network traffic. These consistency checks can also reduce performance impacts at the production system, as test condition generation can be carried out at the quality database system. A consistency check method can include the quality database system determining values of updated or added records of a first table that should be consistent with a second table. The test conditions cause the production database system to execute a test to determine whether the values are present in the production system. Consistency violations can be remedied before the update is applied. |

Replica performance for transactions submitted to log-first distributed databases
By obtaining metadata for transactions submitted by a service to a log-first distributed database of a provider network, a metrics manager may determine database replica performance for those transactions and notify clients of potential performance issues. When an instance of the service submits a write transaction to the log-first distributed database, the transaction may include a host name and a timestamp for the submission of the transaction. At a later point in time, a write applier may obtain the transaction and apply it to a local database replica, along with an additional timestamp for the application of the transaction to the replica. A metrics manager may obtain the transaction timestamps from the replica and calculate a latency metric for the propagation of the transaction from the particular service instance/instance host to the replica. The latency metric may be stored or transmitted to an endpoint (e.g., a client or administrator). |

Accordingly, dynamic adjustment of an EC redundancy ratio is implemented, and the management server may exclude some nodes in the partition from a storage range of the to-be-written data based on a requirement, thereby reducing a data storage IO amount. |

Processor branch prediction circuit employing back-invalidation of prediction cache entries based on decoded branch instructions and related methods
A processor branch prediction circuit employs back-invalidation of prediction cache entries based on decoded branch instructions. The execution information of a previously executed branch instruction is obtained from a prediction cache entry and compared to generated decode information in an instruction decode circuit.

Condition monitoring for components of a gearbox
Conditioning monitoring is provided for rotating components in gearboxes that accounts for gear system dynamics, allowing for improved analysis. A rotation rate for the component is generated from vibration data by estimating the rotation rate based on a tachometer measurement of another shaft and the shaft ratio. This estimated rotation rate is used, together with the known configuration of the component, to estimate a known gear mesh frequency of the component. By filtering for a range of frequencies around the gear mesh frequency based on variation in the shaft rate, the gear mesh frequency can be determined and from that signal, an actual rotation rate for the component can be determined. The actual or determined rotation rate can then be used in deriving an analytic vibration spectrum for the component that is not degraded due to gear system dynamics effects. |

Variable force tensioner arm with cap disk spring
A stack of disk springs are placed between a second piston of a dual hydraulic variable force tensioner system and a hydraulic tensioner arm to allow much higher spring rates if desired. The springs may be stacked in multiple configurations to provide different spring rates. Package space can be reduced depending on the number of springs and orientations of said springs within the tensioner arm. |
