Properties in the data objects for all data sources can be fed to real-time aggregate analysis (performed by the stream-processing platform) to immediately spot patterns of interest in the analytic results generated for each data source. MORE
The obvious impact of this is that in the event of a master failure, the slave will not be up-to-date as its SQL thread is still processing the events in the relay log. This will delay the failover process as our framework expects the slave to be fully up-to-date before it can be promoted. To address this issue, we enable multi-threaded slaves with the option slave_parallel_workers to set the number of parallel SQL threads to process events in the relay logs. MORE
Another thread or process is constantly polling events from the log table and writes them to one or multiple datastores, optionally removing events from the log table after acknowledged by all datastores. Online Event Processing. MORE
