Batch delete items from a table by a Stream of partition key P.

Deduplication logic within a batch is:

within a batch, only send deletion request for one P key and discard all duplicates.

Batch delete items from a table by a Stream of partition key P and sort key S.

Deduplication logic within a batch is:

within a batch, only send deletion request for one (P, S) key pair and discard all duplicates.

Batch get items from multiple tables.

Parallelism should match maximum connections of the underline http client, default is 50: https://github.com/aws/aws-sdk-java-v2/blob/35267ca707c3fb5cdf7e3e98758a8ef969269183/http-client-spi/src/main/java/software/amazon/awssdk/http/SdkHttpConfigurationOption.java#L121

Batch get items from a table by partition key P. A Codec of U is required to deserialize return value based on projection expression.

Batch get items from a table primary keys P and S. A Codec of U is required to deserialize return value based on projection expression.

Batch put items into a table by a Stream of T.

Deduplication logic within a batch is:

within a batch, only send the the last item and discard all previous duplicated items with the same key. Order from upstream is preserved to ensure that only putting the last version of T within a batch.

Batch put items into a table by a Seq of T.

Deduplication logic within a batch is:

within a batch, only send the the last item and discard all previous duplicated items with the same key. Order from upstream is preserved to ensure that only putting the last version of T within a batch.

Batch put unique items into a table.

Batch write to a table by a Stream of either DP (delete) or P (put).

DP: partition key's type P: item being put's type

Deduplication logic within a batch is:

Group all DP and P items by key, preserve ordering from upstream. If the last item for that key is a delete, then only perform deletion, discard all other actions on that key. If the last item for that key is a put, then only perform put, discard all other actions on that key.

Batch write to a table by a Stream of either (DP, DS) (delete) or P (put).

DP: partition key's type DS: sort key's type P: item being put's type

Deduplication logic within a batch is:

Group all (DP, DS) and P items by key, preserve ordering from upstream. If the last item for that key is a delete, then only perform deletion, discard all other actions on that key. If the last item for that key is a put, then only perform put, discard all other actions on that key.
