DBX-6700 Query-based compiler & Multifile support

[huydo862003]

Summary

• BREAKING CHANGE: Revamp the compiler into query-based design.

• Add multifile support into compiler:

  use { table my_table as t } from './a.dbml'
  use * from './b.dbml'
  

  • use: Non-transitive imports
  • reuse: Transitive imports
  • Allow importing of: Table, Enum, TableGroup, Schema, Note (sticky note), TablePartial
    • Ref, Records are automatically pulled if all of its tables are in scope.
    • TableGroup import would also import all of its tables. TableGroup cannot reference imported table, it can only reference the current file's table (for now).
    • Schema import would pull all elements inside that schema into scope.

• Discussion: [Proposal] Support splitting DBML to multiple files #843

• TDD:

  • Query-based compiler: https://www.notion.so/holistics/TDD-94-Query-based-compiler-Overview-of-the-compiler-architecture-345f89dc7e4980e88bc9fd6d140c1d8b
  • Multifile support (reworked): https://www.notion.so/holistics/TDD-91-DBML-Multi-file-Support-319f89dc7e49804f94f6d8d7cd2cdf6e?v=b4c7e791a9664e779faf139f7f7bda40&source=copy_link

Suggested review order

1. Review the TDD for query-based compiler: https://www.notion.so/holistics/TDD-94-Query-based-compiler-Overview-of-the-compiler-architecture-345f89dc7e4980e88bc9fd6d140c1d8b
2. Check the files for Filepath, SyntaxNode, NodeSymbol and the internable types Internable.
3. Check the compiler.ts file:
   a. Check how the local cache & the global cache are setup (localQuery and globalQuery methods).
   b. Check what queries we have: https://www.notion.so/holistics/TDD-94-Query-based-compiler-Overview-of-the-compiler-architecture-345f89dc7e4980e88bc9fd6d140c1d8b?v=b4c7e791a9664e779faf139f7f7bda40&source=copy_link#345f89dc7e49804f8f0edca6282a32c8
4. Check the overall flow of the compiler: Compiler query -> Interning the args -> Check query cache -> Dispatch to query module (chain-of-responsibility) -> Cache the result -> return.
5. Check lexer, parser.
6. Check the local_modules for validator (do not care about multifile support yet).
7. Check the global_modules for binder and interpreter (do not care about multifile support yet).
8. Check the multifile support: check the local modules, global modules for use.
