基于字节流的MySQL8.0 parser

DagonParser

• Chinese documentation

MySQL high-performance parser, use byte stream parsing.

Lexical analysis and grammatical analysis refer to MySQL 8.0

Quick start

Open the /src/test/java folder, select any statement, and run the unit test.

Optimization point

• Pure byte stream analysis, String is not generated if it is not necessary.
• Process all supported SQL, and directly generate the syntax tree after receiving the byte stream to avoid subsequent duplication of work.
• Synchronous collection of relevant information such as SQL summary during grammar analysis.
