# Select API Quickstart Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

Traditional retrieval of objects is always as whole entities, i.e GetObject for a 5 GiB object, will always return 5 GiB of data. S3 Select API allows us to retrieve a subset of data by using simple SQL expressions. By using Select API to retrieve only the data needed by the application, drastic performance improvements can be achieved.

            final GetObjectRequest request = GetObjectRequest.builder().bucket(bucket).key(objectName).build();

                in.transferTo(outputStream);
            }
        } catch (final Exception e) {
