In an ordered array, we can find the arithmetic difference series and use three pointers to move the front and back pointers Based on the middle pointer. Given a set of numbers, findLEngth ofLOngestARithmeticPRogression (LLAP) In it. Examples: set[] = {1, 7, 10, 15, 27, 29}output = 3The longest arithmetic progression is {1, 15, 29}set[] = {5, 10, 15, 20, 25, 30}output = 6The whole set is in AP For simplicity, we have assumed that the given set is sor

: 4 engines have successfully run Atscale's BI benchmark query; Each engine has its own performance benefits, depending on the amount of data, query complexity, and number of concurrent users: Impala and Spark SQL beat other people on small data volumes of queries; Impala and Spark SQL defeated others on a complex join of large data volumes; Impala and Presto perform better on concurrent testing. Compared to benchmark tests 6 months ago, all engines

released Hive 2.0 in February and released Hive 2.1 in June. Improvements to Hive 2.0 include several improvements to Hive-on-spark, as well as performance, availability, support, and stability enhancements. Hive 2.1 includes the Hive Llap ("Live Long and Process"), which combines a persistent query server with an optimized memory cache for high performance. The team claimed to have increased 25 times times. In September, the Hivemall project entered

The team claimed to have increased 25 times times.In September, the Hivemall project entered the Apache incubator, as I pointed out in the second part of my machine learning annual summary.
