With the guideline above, you can now easily ingest large datasets into DynamoDB in a more efficient, cost-effective, and straightforward manner.Technical Specification Sheet Document No.
Post the process, we changed the table settings to Provisioned table with the RCU and WCU required for the application, to make it cost-effective.
#Markx phase dimming generator
#DictReader is a generator not stored in memoryįor row in csv.DictReader(codecs.getreader(‘utf-8’)(obj)):ĭestination_name = rows TableName = ‘personalize_item_id_mapping’īucket = event An overall architecture and data flow is depicted as belowĭynamoDB_client = boto3.resource(‘dynamodb’) The whole pipeline was serverless and the lambda function was configured with the S3 event trigger with the prefix (.csv). Once configured, we tested the Lambda function, the records successfully loaded into DynamoDB table and the whole execution just took around five minutes.
#Markx phase dimming code
Lambda Function with a time out of 15 minutes, which contains the code to export the CSV data to DynamoDB table.We created a DynamoDB demand table with On-Demand for the Read/write capacity to scale automatically.We structured the input data so that the partition key(ItemID) is in the first column of the CSV file.All you need to do is call put_item with table batch writer to ingest the data to DynamoDB table.Ĭonfigurations used for _writer():
In addition, the batch writer will also automatically handle any unprocessed items and resend them as needed. This method returns a handle to a batch writer object that will automatically handle buffering and sending items in batches. With the _writer() operation we can speed up the process and reduce the number of write requests made to the DynamoDB. In our case, the dataset was large and the provisioned table was very slow for ingestion often leading to throughput error or Lambda timing out. We had around 500,000 records under a s3 bucket to be ingested into the DynamoDB table.Ī provisioned DynamoDB table with default settings (5 RCU and 5 WCU) was created with the Partition key (ItemID) and when called with the put _item API call via Lambda, the process was ingesting one record at a time which was sufficient for a record ingestion of a smaller dataset. We faced a use case with a web application requiring millisecond scale results from the database.
