This thing doesn't handle throttling and anything over 1060 simultaneous records to be pulled, here's the session with 2000 records at the time:

Hi, @sokoow .
For me it looks like you exceeded your maximum allowed provisioned throughput for a table.
I see 3 scenarios:

• reduce the frequency of requests or amount of records in request(now it set to 100 records per request, I can make this parameter customizable)
• handle exception and try read records late
• increase throughput capacity for reads

[sokoow]

Well yeah, but this this shouldn't just crash right ?

[shevchenkos]

@sokoow, yes you are right.
For me the best scenario is to notify that there is such a problem, don't stop the process and try later.
