"Hey guys, just had a major DB headache on my node. My queries are taking forever to run because none of the tables are indexed. Anyone else ever come up against this and have some tips to share?"
"Hey OP, same issue happened to me a while back - turned out the table just needed a proper index created. Have you checked the query execution plan and see if it's using an index? Might also wanna optimize the table stats."
"Dude, check your database logs for any recent changes. It's possible that the table just got dropped from the index or the index rebuilding process is still ongoing. Have you tried running an OPTIMIZE TABLE query?"
"Yaaas, indexing is key here. Have you tried running an EXPLAIN on the query to see where it's bottlenecking? Also, are you using any specific indexing method like full-text or composite indexing?"
"Dude, I feel you. I once had a similar issue with a table that wasn't indexed, it was killing my app's performance. Have you checked if the table has any triggers or functions that might be running queries on it unnecessarily?"
