Hi, Basically, we have completed the durable native computing infra. since the last release, so it might be a good time to think about how to introduce the Columnar layout of data into Apache Mnemonic, the reason are
1) to take advantage of the SIMD 2) to optimize the use of CPU caches 3) to compact tensor data I figure out the following approaches for your consideration. a) to build a set of durable columnar collections for data (using MemBuffer or MemChunk as underlying storage) b) to let durable native computing service layout columnar data as needed (possible to gather scattered data using AVX instructions without moving data) Please offer advice, Thanks. Cheers +Gary
