Funny is in order to install percona-toolkit I had to install Oracle MySQL and afterwords change back to MariaDB
brew install mariadb
brew unlink mariadb
brew install percona-toolkit
brew unlink mysql
brew link mariadb
We use Galera cluster with row based replication:
show global variables like 'binlog_format';

I did a simple use case:
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

why is the output empty?
Is pt-query-digest not compatible with MariaDB? Changes in binlog format? Any workaround?
