raiden supports making span for Tracing ( span name is dynamodb::action with table name and api name in field ).
To activate this feature, you need to specify tracing feature in your Cargo.toml. And your crate needs tracing .

# Example
[dependencies]
raiden = {
    tag = "0.0.76",
    git = "https://github.com/raiden-rs/raiden-dynamo.git",
    features = [ "tracing"]
}
tracing = "0.1"

• Docker Engine

AWS_ACCESS_KEY_ID=awsdummy AWS_SECRET_ACCESS_KEY=awsdummy make dynamo

This starts up DynamoDB on Docker container, and then arranges test fixtures.

AWS_ACCESS_KEY_ID=awsdummy AWS_SECRET_ACCESS_KEY=awsdummy make test

NOTE: Don't recommend to use cargo test because our test suite doesn't support running tests in parallel. Use cargo test -- --test-threads=1 instead of it.

dynamodb-admin is useful to check data in DynamoDB Local.

npx dynamodb-admin

Then open http://localhost:8001 in browser.
