Hi, Code refactoring is inevitable when building a large system. The read/write of TsFile, storage engine of the server have been refactored. Now, it's time to refactor the query engine in the server.
Currently, the query is in a tuple-at-a-time manner. In the meantime, the interface is in chaos. To improve the query speed, a batch-at-a-time(vectorization) iteration is needed. I have opened a branch with Lei Rui: f_batch_reader. The existing interfaces are simplified and IBatchReader is added. Welcome to work on this branch for query optimization.
