python - DynamoDB simple scan - getting 0 results -

i'm using dynamodb through python (boto3), trying perform simple table scan keep getting 0 results. when i'm trying use same scan filter on aws console, returns correct # of results..

my request code:

response = table.scan(             filterexpression=attr('datetime').eq(1453630770)         ) 

note: "datetime" attribute number type

note2: table scan without params yielded results correctly

what did wrong? duders

okay, found answer - apparently i've reached max response size (large objects) , fixed iterating dynamodb table using 'lastevaluatedkey'

a few rounds of scans yielded results properly.

while 'lastevaluatedkey' in response:         response = table.scan(             projectionexpression=pe,             filterexpression=fe,             expressionattributenames= ean,             exclusivestartkey=response['lastevaluatedkey']             )
