Re: slow update-join query
Sorry for the confusion. I actually updated my query with the correct column names so that everything else makes sense. I left the column names as is for the columns that are being used in the query. Pasting the actual query again.
update table1 a, table2 t set a.current_version = 1 where a.source_article_id = t.source_article_id and a.version = t.max_version;
Can you please reanalyze my previous reply with this query in mind. And also, please see the note about ranged queries I tried. I didnt change anything in the table schema before I ran those, Any insights into why the 10 mil ranged query was fast enough but the entire query wasn't - will be helpful. Thanks!
