      Description

      A customer is proposing the following index to improve database performance .

      CREATE INDEX idx_is_root ON avm_nodes (is_root) USING BTREE;

      The query to benefit from this index is:

      select an.* from avm_child_entries ce right outer join avm_nodes an on an.id = ce.child_id where ce.parent_id is null and an.is_root = 0;

      The query plan for this query is:

      ----------------------------------------------------------------------------------------------------------------------+

      id select_type table type possible_keys key key_len ref rows Extra

      ----------------------------------------------------------------------------------------------------------------------+

      1 SIMPLE an ALL NULL NULL NULL NULL 3 Using where
      1 SIMPLE ce ref fk_avm_ce_child fk_avm_ce_child 8 alfresco310.an.id 1 Using where; Using index; Not exists

      ----------------------------------------------------------------------------------------------------------------------+
