How is fat record read



Let’s say we have a records with thousands of bins and stored in persistence mode only (record size < 1MB). Set size (~20GB). And the query (TPS ~100/sec) is made by selecting 50 bins at a time for the given record key ie select bin1, bin5, bin 12, …, binX from set where key = ‘’.

Does Aerosike load entire record (fat) in memory and return filtered data?


If you data is stored in memory, yeah the thing is already loaded into memory. Are you talking about what happens on the client or the server?


Yes. Stored in persistence mode --> on disk or SSD - its going to first read the entire record in RAM and then return to the client the selected bins - so you save on network bandwidth only.
