The default value size of each put is 10 bytes and you can set it by the config key:

-==== Treat read / write failure as error
-
-By default, the canary tool only logs read failure, due to e.g. RetriesExhaustedException,
-while returning normal exit code. To treat read / write failure as error, you can run canary
-with the `-treatFailureAsError` option. When enabled, read / write failure would result in error
