(bedrock): (custom data sources)

[ipa-tys]

Describe the feature

It seems that at the moment the bedrock module does not support custom data sources. This is also documented here:
https://awslabs.github.io/generative-ai-cdk-constructs/src/cdk-lib/bedrock/#vector-knowledge-base---data-sources

Would it be possible to add this feature? In python code, it is straightforward, cf. example below. I would also be happy to give it a try myself, but I would need some hints.

response = bedrock_agent_client.create_data_source(
    name = 'devkb',
    description = 'devdatasource',
    knowledgeBaseId = 'myid',
    dataSourceConfiguration = {
        "type": "CUSTOM"
    },
    vectorIngestionConfiguration = {
        "chunkingConfiguration": chunkingStrategyConfiguration
    }
)

Use Case

Custom data sources are an important feature for Bedrock Knowledge Bases for all but very standard use cases.

Hi @ipa-tys , I can see that the type 'CUSTOM' is available in CloudFormation (cf https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-bedrock-datasource-datasourceconfiguration.html).
It would require to update the enum here and then probably exposing a new custom-data-source.ts to implement the related logic. I didn't play with that feature yet so not familiar with the specifics.
I will add it to the backlog, thank you !

Hi @krokoko , thanks for the helpful and quick reply! I had a quick look, but as I'm not well-versed in TypeScript, I was not able to quickly contribute the feature myself. Would be great if someone else would be capable to pick it up.
