Abstract: Methods and systems for executing non-blocking transactions at a database are provided. The method includes receiving a write transaction that is directed to a partition of a table stored by a cluster of database nodes. The method includes generating, at a database node of the cluster, a synthetic timestamp based on a first time associated with the database node and a duration, wherein the synthetic timestamp exceeds the first time by the duration. The method includes executing, based on determining the synthetic timestamp, one or more operations of the write transaction at one or more replicas of the partition. The method includes committing, based on a threshold number of acknowledgements, the one or more operations of the write transaction at the one or more replicas. The method includes sending, based on a second time exceeding the synthetic timestamp, an indication of success of the write transaction.

Abstract: Methods and systems for multi-region database configuration in a distributed computing system are disclosed. A database comprising at least three voting replicas of a partition of a table is stored by a cluster of computing nodes. The database corresponds to one or more database regions that are each indicative of a geographic location corresponding to the cluster of computing nodes. Each of the voting replicas participates in voting to commit write operations to the partition. At least three computing nodes of the cluster each store a respective voting replica of the voting replicas, where each of the computing nodes is located within one of a first, second, or third database region of the database regions. Each of the database regions that does not store one of the voting replicas stores a non-voting replica that does not participate in the voting to commit the write operations to the partition.

Abstract: A modular tool system is disclosed herein with a power unit, a battery, a controller, a sensor, and a plurality of tool modules. The hand-held sized power unit can include a motor housing and a motor with a shaft. The controller can variably control the shaft. Each tool module can include a housing, a work-engaging portion, a transmission linkage, and an identifier. The identifier is within a range of detection of the sensor when the housings are coupled. Each of the identifiers is distinguishable from other identifiers and the sensor transmits a different signal for each of the identifiers. The controller is configured to determine one of a plurality of different shaft speeds or one of a plurality of different torques to transmit through the shaft in response to the signal from the sensor indicating a particular identifier.
