Amazon DynamoDB Agent for Gluesync: Key Features

Index

Core principles

Gluesync uses the SDK provided by AWS for DynamoDB to connect and consume the DynamoDB APIs.

Change data capture

CDC is implemented using the native APIs called DynamoDB Streams. To read more about DynamoDB Streams please refer to the official AWS documentation available here at this link.

Security

Gluesync replication supports secure communication via TLS encryption when connecting to the DynamoDB cluster, this is an always-on feature.

Supported version

Works within any AWS region where DynamoDB is deployed.

Platform supported features

Feature	Support	Notes
Target role	✅	Writes to DynamoDB through the official AWS SDK with TLS enforced by default.
Source role	✅	Consumes DynamoDB Streams to capture real-time changes from tables in any region.
Snapshots	✅	Supports Core Hub snapshot tasks that scan DynamoDB tables for initial loads.
CDC	✅	Continuous replication based on Streams shards for near real-time forwarding.
CDC type	DynamoDB Streams	Relies on AWS’s native change stream API (Streams docs).
Bulk load	N/A	Bulk staging tables only apply to relational stores; DynamoDB snapshots + Streams handle throughput needs.
Source persisted internal cache	N/A	State tracking lives in Core Hub metadata; agent does not maintain its own disk cache.
Target persisted internal cache	N/A	Writes go straight to DynamoDB via the AWS SDK.
Driver / connector	AWS SDK for Java/Kotlin	Gluesync embeds the official AWS DynamoDB SDK.
Chains	N/A	Not supported being it a NoSQL database.
Truncate operation support (reading)	N/A	DynamoDB has no TRUNCATE primitive; deletions must be explicit.
Truncate operation support (writing)	N/A	Targets cannot issue TRUNCATE-equivalent operations on DynamoDB tables.
