minimizes blocking.Brief introductionWhen you initially design SQL Server, assume that the main memory is very expensive, so unless the data really needs to be processed, the data resides on disk. This assumption is no longer valid because memory prices have fallen sharply in the past 30 years. At the same time, multicore servers are no longer expensive, so today it takes less than $50,000 to buy a server with 32 cores and 1TB of memory. Because many

tolerance than other tools?Existing data flow systems are less efficient at processing two applications: iterative algorithms, which are common in graph applications and machine learning fields, and interactive data mining tools. In both cases, storing the data in memory can greatly improve performance. To effectively implement fault tolerance, the RDD provides a highly restricted shared memory that the RDD is read-only and can only be created through bulk operations on other rdd. Nonetheless,
