29.12.21.4 The innodb_redo_log_files Table

The innodb_redo_log_files table contains a row for each active InnoDB redo log file. This table was introduced in MySQL 8.0.30.

The innodb_redo_log_files table has the following columns:

• FILE_ID

  The ID of the redo log file. The value corresponds to the redo log file number.

• FILE_NAME

  The path and file name of the redo log file.

• START_LSN

  The log sequence number of the first block in the redo log file.

• END_LSN

  The log sequence number after the last block in the redo log file.

• SIZE_IN_BYTES

  The size of the redo log data in the file, in bytes. Data size is measured from the END_LSN to the start >START_LSN. The redo log file size on disk is slightly larger due to the file header (2048 bytes), which is not included in the value reported by this column.

• IS_FULL

  Whether the redo log file is full. A value of 0 indicates that free space in the file. A value of 1 indicates that the file is full.

• CONSUMER_LEVEL

  Reserved for future use.
