Hi,

This project use the GitHub action rlespinasse/github-slug-action on the master branch.



Due to changes into the branches management, the master branch is not longer supported and will be removed in few months (EOL: 2020-10-25).



The current latest version is 2.0.0 from the v2.x branch.

- uses: rlespinasse/[email protected]
- uses: rlespinasse/[email protected]


If you want to avoid breaking changes, you can use the 1.1.0 version or the v1.1.x branch.

• setup
• basic queries
• batch operations
• advanced combinators
• etc ???

DynamoDB supports contains (SET, ELEM) & size(X) functions that are currently missing in Condition DSL

given a case class X(option: Option[Int]), derived D4SDecoder will not decode an empty object {} as X(None) - however a circe-based decoder would. Need to address that.

DynamoEnv should inherit DistageAbstractScalatestSpec and provider its own TestConfig

It looks kinda noisy

  implicit def optionEncoder[T: D4SAttributeEncoder]: D4SAttributeEncoder[Option[T]] = {
    item: Option[T] =>
      item.map(encode[T]).getOrElse(AttributeValue.builder().nul(true).build())
  }

when we need to

  implicit def optionEncoder[T: D4SAttributeEncoder]: D4SAttributeEncoder[Option[T]] = {
    item: Option[T] =>
      item.map(encode[T]) // expects Optional attribute to not write unnecessary parts
  }

Decoder already supports optional attributes.

Also, we need to show how to set up a project without DI in case someone is allergic to that technic or just don't want to bring it to their project.

We removed circe dependency in metrics module, but it very convenient to have a possibility to pass metrics over HTTP. We could provide circe codecs for MetricsDef in circle module.

We've already made an attempt to do this.
here is the code:

The problem is we constantly encounter the following issue:

super constructor cannot be passed a self-reference unless parameter is declared by-name
 object Table1Key extends WithD4S[Table1Key]
