Abstract: Embodiments herein describe a retroactive tracer that retroactively generates traces using data stored in local caches. Rather than continually generating and collecting tracing data in a distributed system (which may requires massive amounts of storage and bandwidth), the embodiments herein store tracing data in local caches corresponding to nodes in the distributed system (e.g., a service, application, virtual machine, server, network device, etc.). When an error is detected when executing a task, the retroactive tracer can broadcast a request that the nodes send any trace data they may have corresponding to that task. The tracer can then retroactively generate the trace from the collected trace data. In contrast, if a task completes without an error, the nodes delete the trace data from their local caches (i.e., the trace data is not collected by the retroactive tracer).

Abstract: A distributed database maintains a table on a first plurality of partitions. A request to restore the table to a point-in-time is received. The database determines, based on log data of the partitions, a maximum version number of an operation processed by the partitions. The log data is processed to exclude, from the restoration, operations whose transactions were started after the point-in-time, by setting the version number of those operations to be greater than the maximum version number. The log data is then applied to a second plurality of partitions, where the version number of each applied operation is less than or equal to the determined maximum version number.

Abstract: A sensing device is for sensing an operating voltage of a remote device. A communications interface receives communications signals originating from the remote device over a communications bus. A data sampler takes data readings of a communications signal at a predetermined set of timing instants defined by the sensing device. A data metric (such as a duty cycle of high and low states) is obtained from the data readings and from this 5 an operating voltage of the remote device is obtained, based on a relationship between the voltage and the data metric. The invention is based on detecting timing changes which result from voltage changes. In particular, the slope of rising and falling edges of the communications signal are influenced by the voltage level, and this in turn influences the timing of high states (1s) and low states (0s).
