A method of and system for asynchronous replication of data from a source database to a destination database is carried out by utilizing a probabilistic replication filter to manage the state of replication. The method may include receiving a list of identifiers for a plurality of entities in a data set in the source database, loading at least a portion of the list into a probabilistic replication filter, the portion including an identifier for each one of the plurality of entities in the data set that have not yet been replicated in the destination database, examining the list of identifiers to determine if a first identifier is in the probabilistic replication filter, and upon determining that the first identifier is in the probabilistic replication filter, replicating an entity associated with the first identifier and removing the first identifier from the probabilistic replication filter.

Data replication using probabilistic replication filters

The performance of a cloud-based software product over time is determined by collecting telemetry data representing whether different features of online sessions of the software product are operating properly. The telemetry data represents shared performance metrics of the software product across different participants and components participating in an online session. The collected telemetry data is correlated with session identifiers identifying the online session from which the telemetry data was collected. The telemetry data for an online session is processed to establish a unit of failure when the telemetry data indicates that the online session operated outside of predefined performance metrics. The unit of failure is a function of vetoes applied to a candidate list of online sessions indicating that the online session may have problems. The performance of the software product may be determined as a function of the unit of failure over time.
