scan 'my_table', {FILTER=>"(RowFilter (=, 'binary:my_row_key))"}

1 row(s) in 11.5820 seconds

get 'my_table', "my_row_key"

13 row(s) in 0.0460 seconds

At this rate, it appears doing list of gets is more efficient than doing a single scan

Have a look at Table.rows(). The scan with a filter in your comment does a full table scan and will get much slower when your data grows. Never use filters without specifying row key ranges, except for one shot queries.
