Other patches

  1. MySQL 8.4 minor version is updated to MySQL 8.4.6.
  2. Implemented a fail-fast mechanism to mitigate Bug #118888. This change prevents MySQL from entering an infinite loop and exhausting all disk space. MySQL now immediately reports the following actionable error: ERROR HY000: Internal error: Per-thread DDL buffer is too small. Consider increasing --innodb_ddl_buffer_size or decreasing --innodb_parallel_read_threads.
