Improve The Core

• speed up the join process and postprocessing of SPARQL using GPU or FPGA

• improve the indices and support concurrent reads

• add numeric value query function. need to answer numeric range query efficiently and space consume cannot be too large

• typedef all frequently used types, to avoid inconsistence and high modify cost

Better Interface

• the usability of ghttp(ERROR_CODE, API ...)

• improve socket interface

• docker settings

Idea Collection Box

• warnings remain in using Parser/(antlr)!(modify sparql.g 1.1 and regenerate). change name to avoid redefine problem(maybe error), or go to use executable to parse

• mmap to speedup KVstore?

• the strategy for Stream:is 85% valid? consider sampling, analyse the size of result set and decide strategy? how to support order by: sort in memory if not put in file; otherwise, partial sort in memory, then put into file, then proceed external sorting
