Support for DynamoDB compatible services

Thu, 11 May 2023 12:18:56 +0000

Hi!
There is a DynamoDB compatible service called YDB.
YDB in the Yandex Cloud has a serverless mode with DynamoDB support..

So I have:

AWS_ACCESS_KEY_ID
AWS_SECRET_KEY
region: ru-central1
endpoint like https://docapi.serverless.yandexcloud.net/ru-central1/b1gia87mbaomkfvs6rgl/etnudu2n9ri35luqe4h1

I have tried using the ddb and ddb-local protocols with different settings.

Variants of aws-dynamodb-override-endpoint
1. docapi.serverless.yandexcloud.net/ru-central1/.../...
2. docapi.serverless.yandexcloud.net:443/ru-central1/.../...
3. https://docapi.serverless.yandexcloud.net/ru-central1/.../...

$ bin/datomic ensure-transactor config/ddb.properties config/ddb-gen.properties
java.lang.IllegalArgumentException: java.net.URISyntaxException: Illegal character in authority at index 7: http://"https://docapi.serverless.yandexcloud.net/ru-central1/b1g31q09ln3ca15cg5mf/etnckvjnbskiko1s639l"

	at com.amazonaws.AmazonWebServiceClient.toURI(AmazonWebServiceClient.java:329)
	at com.amazonaws.AmazonWebServiceClient.setEndpoint(AmazonWebServiceClient.java:317)
	at datomic.ddb$client.invokeStatic(ddb.clj:14)

I think that ddb-local always uses http protocol and there is no way to configure it with https.

There are some examples of using AwsSDK with YDB in Yandex cloud

AmazonDynamoDB client = AmazonDynamoDBClientBuilder.standard()
          .withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration("<Document API endpoint>", "ru-central1"))
          .build();

Could you add support for DynamoDB compatible services?
Could it be the new `aws-dynamodb-override-protocol' setting, which is by default 'http' ?
