The innodb_redo_log_files table contains a
row for each active InnoDB redo log file.
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.
