Instance Method Details
#each(&block) ⇒ Enumerable<Aws::Record>
Provides an enumeration of the results of a query or scan operation on your table, automatically converted into item classes.
WARNING: This will enumerate over your entire partition in the case of query, and over your entire table in the case of scan, save for key and filter expressions used. This means that enumerable operations that iterate over the full result set could make many network calls, or use a lot of memory to build response objects. Use with caution.

#empty? ⇒ Boolean
Checks if the query/scan result is completely blank.
WARNING: This can and will query your entire partition, or scan your entire table, if no results are found. Especially if your table is large, use this with extreme caution.
