pt-query-digest --type binlog (percona-toolkit) dá uma saída vazia com MariaDB/Galera 10.1

Minhas versões instaladas do MariaDB e Percona Toolkit no MacBook:

brew info percona-toolkit

Engraçado é que para instalar o percona-toolkit eu tive que instalar o Oracle MySQL e depois mudar de volta para o MariaDB

brew install mariadb
brew unlink mariadb
brew install percona-toolkit
brew unlink mysql
brew link mariadb

Usamos o cluster Galera com replicação baseada em linha:

show global variables like 'binlog_format';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| binlog_format | ROW   |
+---------------+-------+
1 row in set (0.00 sec)

Eu fiz um caso de uso simples:

mysqlbinlog  mysql-bin.0013* > all.sql

pt-query-digest --type binlog all.sql
all.sql:   1% 37:37 remain
(...)
all.sql:  96% 01:23 remain
all.sql:  98% 00:30 remain

por que a saída está vazia? Não pt-query-digesté compatível com MariaDB? Mudanças no formato de log binário? Alguma solução alternativa?
