Moralis Query Issue

i am getting one issue while query from moralis database
sometimes it throws an error Returned error: limit exceeded can you please tell me why and how i can resolve this ?

what is an example of query that gets that error?

we are fetching the records from table where isProcessed value is false

how many records should return? 10, 100, 1k, 20k?
