getAll with limits

Hello,

I have an issue here where I need to get the last 2000 records from an indexeddb store. Since it's used for logging, the value on a record can be big. What's the best solution to do this. I tried putting an index on the primary key, and use a query with a between on the index, but it's really slow. Would it be possible to use a limit on the getall? 

Thanks in advance!
