Class profile::analytics::refinery::job::data_purge

Installs systemd-timer jobs to drop old hive partitions, delete old data from HDFS and sanitize EventLogging data.

deploy_jobs

Temporary flag to avoid deploying jobs on new hosts. Default: true

Parameters:

  • public_druid_host (Optional[String]) (defaults to: lookup('profile::analytics::refinery::job::data_purge::public_druid_host', { 'default_value' => undef }))
  • ensure_timers (Wmflib::Ensure) (defaults to: lookup('profile::analytics::refinery::job::data_purge::ensure_timers', { 'default_value' => 'present' }))
  • use_kerberos_keytab (Boolean) (defaults to: lookup('profile::analytics::refinery::job::data_purge::use_kerberos_keytab', { 'default_value' => true }))
