Handling WriteRecords throttles

Your memory store write requests to Timestream may be throttled as Timestream scales to adapt to the data ingestion needs of your application. If your applications encounter throttling exceptions, you must continue to send data at the same (or higher) throughput to allow Timestream to automatically scale to your application's needs.

Your magnetic store write requests to Timestream may be throttled if the maximum limit of magnetic store partitions receiving ingestion. You will see a throttle message directing you to check the ActiveMagneticStorePartitions Cloudwatch metric for this database. This throttle may take up to 6 hours to resolve. To avoid this throttle, you should use the memory store for any high throughput ingestion workload. For magnetic store ingestion, you can target ingesting into fewer partitions by limiting how many series and the time duration that you ingest into
