Design references needed for Calcite

[S.Yin]

Hi all,


I am currently using Calcite in our project and am feel very difficult to
understand the terminology and concept from those examples. Currently I
feel I kind of get the idea but still want to understand it from inside and
out.

Instead of reading all the source code, Can anyone refer to any papers and
tutorials I can check on? Especially the high level design and terminology.

E.g. what is SqlParserPos used for.

Thanks.
