EMsnap opened a new pull request, #6128:
URL: https://github.com/apache/inlong/pull/6128

   - Fixes #6113 
   
   ### Motivation
   
   The Mysql Connector for extracting data now doesn't support reading table 
schema when there is no primary key specified.
   Canal Json requires field names called mysqlType and sqlType which contains 
information in table schema
   The pr modifies the implementation of debezium function to get table schema 
from debezium databaseHistory
   
   ### Modifications
   
   1 Add a new meta field called DATA_BYTES to represent the canal presentation 
of a record
   2 make the table schema contained in databasehistory static
   3 fill canal json with info from table schema
   
   ### Verifying this change
   
   run AllMigrateTest
