    Description

      Many in-core performance optimization opportunities exist in zebra, such as removal of redundant precautionary checks, use of better collection types to reduce levels of indirection to the memory objects, changing of input splits in ascending sizes to descending sizes. Observed improvements of wall clock time of some PIG LOAD queries are around 10%.
