Licensing options for this format begin with FME Professional Edition.
The DynamoDB Reader/Writer module enables FME to read and write DynamoDB attribute data.
Overview
DynamoDB is a managed NoSQL database service offered by Amazon Web Services.
The DynamoDB reader/writer communicates using HTTP requests managed by the Amazon Web Services Java SDK.
This chapter assumes familiarity with DynamoDB, the attribute types supported, and its indexing mechanisms.

Reader Overview
FME considers a DynamoDB dataset to be a database containing a collection of tables. The tables must be defined in Workbench before they can be read.
When reading from the DynamoDB database, each table is considered a feature type in FME and each row of a table one feature in FME.
Open the Workbench DynamoDB Reader Parameters to view the table list options.
Writer Overview
The DynamoDB writer module stores attributes into a DynamoDB database. The DynamoDB writer provides the following capabilities:
- Index Creation: The DynamoDB writer can set up and populate indexes as part of the loading process. When creating a table, a partition key index must be specified. One additional column can be indexed using DynamoDB’s sort key index. The DynamoDB writer also supports the creation of a single global or local secondary index.
- Batch Writes: The DynamoDB writer writes in batches of up to 25 items in order to ensure a faster data loading process. The maximum number of items processed in a single batch can be changed using the Batch Size writer parameter.
