aria_read_log

aria_read_log is a tool for displaying and applying log records from an Aria transaction log.

Note: Aria is compiled without -DIDENTICAL_PAGES_AFTER_RECOVERY which means that the table files are not byte-to-byte identical to files created during normal execution. This should be ok, except for test scripts that try to compare files before and after recovery.

Usage:

aria_read_log OPTIONS
