      Description

      It seems the recently added variable eq-range-index-dive-limit cannot be configured in server cnf file.
      In configuration file I have:

      [mariadb]
      eq_range_index_dive_limit=200
      

      But the server starts up with message:

       
      localhost.localdomain mysqld[14716]: 2019-05-13 23:02:08 0 [Warning] 'eq-range-index-dive-limit' is MySQL 5.6 / 5.7 compatible option. To be implemented in later versions.
      

      and value is zero in server runtime variables

      MariaDB [(none)]> show global variables like 'eq_range_index_dive_limit'\G
      *************************** 1. row ***************************
      Variable_name: eq_range_index_dive_limit
              Value: 0
      
      

      But setting it manually seems to work as expected.
