sdojjy · 2021-12-13T06:59:07Z

What problem does this PR solve?

close https://github.com/pingcap/ticdc/issues/3755

What is changed and how it works?

not use regex to parse and add special TiDB comments, If a DDL already has special comment like /*!90000 SHARD_ROW_ID_BITS=4 PRE_SPLIT_REGIONS=3 */, it wil translate that DDL to /*!90000 /*T! SHARD_ROW_ID_BITS=4 PRE_SPLIT_REGIONS=3 */ */, TiDB will throw a syntax error.
this PR use the TiDB SQL parser to parse the SQL and the Restore it with format.RestoreStringSingleQuotes|format.RestoreNameBackQuotes|format.RestoreKeyWordUppercase|format.RestoreTiDBSpecialComment flag
