New Resource: aws_dynamodb_table_item #3238

radeksimko · 2018-02-02T11:07:27Z

Replacement for #1378

Closes #517

This is a rough summary of my changes I added on top of @galadriel2143's PR:

Use standard retry helpers
Simplify code by extracting code into reusable functions
Remove fields which seemed unnecessary - if there's any interest we can add them later, but I think they'd unnecessarily increase the complexity of otherwise simple resource
Add validation
Add missing acceptance tests
Add missing docs

The original commit was retained, so @galadriel2143 can still receive the credit they deserve. 😉

@radeksimko any thoughts on a similar data resource? For us we would use it to read values out of dynamodb and feed them to terraform resources.

@lorengordon Do you mind opening a separate issue for that? We can track the interest and related discussion through it. Thanks.

Overall nothing blocking here. 😄 I left some notes but nothing really blocking from my perspective.

aws/resource_aws_dynamodb_table_item.go

+	_, err = retryDynamoDbTableItemOperation(func() (interface{}, error) {
+		return conn.PutItem(&dynamodb.PutItemInput{
+			Item: attributes,
+			// Explode if item exists. We didn't create it.


👍 we can always add an overwrite flag later if necessary

aws/resource_aws_dynamodb_table_item.go

+		var err error
+		out, err = f()
+		if err != nil {
+			if isAWSErr(err, dynamodb.ErrCodeLimitExceededException, "Subscriber limit exceeded:") {


Question: Should we move this logic up to dynamodbconn?

website/docs/r/dynamodb_table_item.html.markdown

+
+Provides a DynamoDB table item resource
+
+-> **Note:** This resource is not meant to be used for managing _all_ data in your table (unless your table contains just a handful of records), it won't scale.


While I agree the contents of this note are important contextually, we might want to change the wording here a little bit:

Changing _all_ data into large amounts of data since it is not designed to scale

Removing It's not supposed to serve as a backup solution either. and instead just implying this in the next sentence by saying full table **regular backups**.

(note: I agree with the original intent of the sentence) The last sentence is a little awkward since generally in our documentation we don't prescribe solutions for people's application/infrastructure problems in an architecture sense (unless its between competing Terraform resources). DynamoDB might be a good fit for some folks and it could be off-putting to tell them how they should be doing things. I'm not sure if there's a better way to say it, but something to consider.

I removed the last sentence, looking back I agree it did sound a little bit biased.

aws/resource_aws_dynamodb_table_item_test.go

+		if err != nil {
+			return err
+		}
+		expectedCount := int64(count)


Nitpick: I think we can rid of this line if we just int64 the type in the signature. 😄

- Use standard retry helpers - Simplify code by extracting code into reusable functions - Add validation - Add missing acceptance tests - Add missing docs
