Accomplishments Includes :● Developed new operators like join, sampling & hash aggregate, based on underlyingSnappyData table location. Also, used code generation and vectorization technique for theabove operators for faster execution.● Query engine enhancements for transactions and snapshot isolation support.● Developed a new memory management module to allocate runtime and storage memorybased on the configured sizes. This module helped to reduce the GC cycles & OutOfMemoryissues.● Co-authored a paper for SIGMOD, which was selected. (http://dl.acm.org/citation.cfm?id=2899408
