Dynamo is incredibly hard to use correctly
I’d urge you to start writing a prototype, a lot of your assumptions might get thrown out the window. Dynamo is not necessarily good for reading high volume. You’ll end up needing to use a parallel scan approach which is not fast.
- qvrjuec 5y agoI'd say Dynamo is extremely good at reading high volume, with the appropriate access pattern. It's very efficient at retrieving huge amounts of well partitioned data using the data's keys, but scanning isn't so efficient.
- whalesalad 5y agoYou can only ever fetch 1MB of data at a time though, even when using the more efficient query method (as opposed to scan). If your individual entities are not very tiny, it is hard to get for instance 2M items back in a reasonable amount of time.
