View Maintenance in Web Data Platforms

Modern Web Data Platforms (WDPs) handle large amount of data and activity through massively distributed infrastructures. To achieve performance and availability at Internet scale, WDPs restrict querying capability, and provide weaker consistency guarantees than traditional ACID transactions. The sheer volume of parallel processing without ACID transaction guarantees, and the large number of independent components in WDPs pose special challenges for view maintenance with respect to concurrent update propagation and correct execution of non-idempotent view updates in the presence of failures.
