AWS Lambda Function Timeout When Accessing DynamoDB with AWS SDK for Java
I'm prototyping a solution and I'm currently working with a timeout scenario with my AWS Lambda function when trying to access a DynamoDB table using the AWS SDK for Java... My Lambda function is set to a timeout of 10 seconds, but the operation often exceeds that time, resulting in a `Task timed out after 10.00 seconds` behavior. This is critical since I need to process user data quickly, and delays are affecting user experience. Here's a snippet of the code I'm using to access DynamoDB: ```java import com.amazonaws.services.dynamodbv2.AmazonDynamoDB; import com.amazonaws.services.dynamodbv2.AmazonDynamoDBClientBuilder; import com.amazonaws.services.dynamodbv2.document.DynamoDB; import com.amazonaws.services.dynamodbv2.document.Table; import com.amazonaws.services.dynamodbv2.document.Item; public class MyLambdaFunction { public void handleRequest(Map<String, Object> input, Context context) { AmazonDynamoDB client = AmazonDynamoDBClientBuilder.standard().build(); DynamoDB dynamoDB = new DynamoDB(client); Table table = dynamoDB.getTable("UserData"); try { Item item = table.getItem("userId", input.get("userId")); context.getLogger().log("Retrieved item: " + item.toJSONPretty()); } catch (Exception e) { context.getLogger().log("behavior accessing DynamoDB: " + e.getMessage()); } } } ``` I have verified that the Lambda execution role has the necessary permissions to access the DynamoDB table. Additionally, I enabled logging for DynamoDB operations to ensure that the requests are being received. However, it seems like the function still takes too long to return. I also tried increasing the Lambda timeout to 30 seconds, but that feels more like a band-aid than a solution. I suspect there might be issues with the way I'm configuring the DynamoDB client or the network latency between Lambda and DynamoDB. Any insights on how to optimize this or debug further would be greatly appreciated! I'm on CentOS using the latest version of Java. Any pointers in the right direction?
