Hi,
I have a query that has to run on a full text indexed table with many
millions of records. I'm trying to figure out some optimizations for
it. Here's the general query:
SELECT SQL_CALC_FOUND_ROWS table_1.id,table_2.*
FROM table_2
LEFT JOIN table_1 ON table_2.shared_id = table_1.shared_id
WHERE MATCH table_2.field AGAINST ('value')
AND table_2.current = 1
AND table_2.shared_id IN (SELECT shared_id FROM table_1_view)
Some details:
1. table_1.shared_id and table_2.shared_id are indexed
2. table_2.current is an indexed tinyint
3. table_1_view is derived from a query like:
SELECT shared_id
FROM table_1
WHERE some_field LIKE 'some_value%'
table_1 is a relatively small table i.e. < 100k records
table_2 is massive with > 10 million records
Any ideas or suggestions are appreciated
thanks,
Eben
