That is very valid. I looked into indexes:
test_user@db2083.codfw.wmnet(wikidatawiki)>show index from wb_terms; +----------+------------+---------------------+--------------+---------------------+-----------+-------------+----------+--------+------+------------+---------+---------------+ | Table | Non_unique | Key_name | Seq_in_index | Column_name | Collation | Cardinality | Sub_part | Packed | Null | Index_type | Comment | Index_comment | +----------+------------+---------------------+--------------+---------------------+-----------+-------------+----------+--------+------+------------+---------+---------------+ | wb_terms | 0 | PRIMARY | 1 | term_row_id | A | 1585960379 | NULL | NULL | | BTREE | | | | wb_terms | 1 | wb_terms_text | 1 | term_text | A | 528653459 | NULL | NULL | | BTREE | | | | wb_terms | 1 | wb_terms_search_key | 1 | term_search_key | A | 28835643 | NULL | NULL | | BTREE | | | | wb_terms | 1 | tmp1 | 1 | term_language | A | 4217979 | NULL | NULL | | BTREE | | | | wb_terms | 1 | tmp1 | 2 | term_type | A | 2969963 | NULL | NULL | | BTREE | | | | wb_terms | 1 | tmp1 | 3 | term_entity_type | A | 6446993 | NULL | NULL | | BTREE | | | | wb_terms | 1 | tmp1 | 4 | term_search_key | A | 577132 | NULL | NULL | | BTREE | | | | wb_terms | 1 | term_full_entity | 1 | term_full_entity_id | A | 144178216 | NULL | NULL | YES | BTREE | | | | wb_terms | 1 | term_search_full | 1 | term_language | A | 7552192 | NULL | NULL | | BTREE | | | | wb_terms | 1 | term_search_full | 2 | term_full_entity_id | A | 1585960379 | NULL | NULL | YES | BTREE | | | | wb_terms | 1 | term_search_full | 3 | term_type | A | 1585960379 | NULL | NULL | | BTREE | | | | wb_terms | 1 | term_search_full | 4 | term_search_key | A | 1585960379 | 16 | NULL | | BTREE | | | +----------+------------+---------------------+--------------+---------------------+-----------+-------------+----------+--------+------+------------+---------+---------------+ 12 rows in set (0.04 sec)
1- The indexes are pretty different from what we have in the code
2- I dropped all of not-needed indexes:test_user@db2083.codfw.wmnet(wikidatawiki)>show index from wb_terms; +----------+------------+------------------+--------------+---------------------+-----------+-------------+----------+--------+------+------------+---------+---------------+ | Table | Non_unique | Key_name | Seq_in_index | Column_name | Collation | Cardinality | Sub_part | Packed | Null | Index_type | Comment | Index_comment | +----------+------------+------------------+--------------+---------------------+-----------+-------------+----------+--------+------+------------+---------+---------------+ | wb_terms | 0 | PRIMARY | 1 | term_row_id | A | 1585960379 | NULL | NULL | | BTREE | | | | wb_terms | 1 | wb_terms_text | 1 | term_text | A | 528653459 | NULL | NULL | | BTREE | | | | wb_terms | 1 | term_full_entity | 1 | term_full_entity_id | A | 144178216 | NULL | NULL | YES | BTREE | | | +----------+------------+------------------+--------------+---------------------+-----------+-------------+----------+--------+------+------------+---------+---------------+ 3 rows in set (0.03 sec)I'm running an optimize table on it to reclaim the space and see how much it opens up...
