Struct dynamo_es::DynamoEventRepository

pub struct DynamoEventRepository { /* private fields */ }

An event repository relying on DynamoDb for persistence.

Implementations

impl DynamoEventRepository

pub fn new(client: Client) -> Self

Creates a new DynamoEventRepository from the provided dynamo client using default table names.

use aws_sdk_dynamodb::Client;
use dynamo_es::DynamoEventRepository;

fn configure_repo(client: Client) -> DynamoEventRepository {
    DynamoEventRepository::new(client)
}

pub fn with_streaming_channel_size(self, stream_channel_size: usize) -> Self

Configures a DynamoEventRepository to use a streaming queue of the provided size.

Example: configure the repository to stream with a 1000 event buffer.

use aws_sdk_dynamodb::Client;
use dynamo_es::DynamoEventRepository;

fn configure_repo(client: Client) -> DynamoEventRepository {
    let store = DynamoEventRepository::new(client);
    store.with_streaming_channel_size(1000)
}

pub fn with_tables(self, event_table: &str, snapshot_table: &str) -> Self

Configures a DynamoEventRepository to use the provided table names.

Example: configure the repository to use “my_event_table” and “my_snapshot_table” for the event and snapshot table names.

use aws_sdk_dynamodb::Client;
use dynamo_es::DynamoEventRepository;

fn configure_repo(client: Client) -> DynamoEventRepository {
    let store = DynamoEventRepository::new(client);
    store.with_tables("my_event_table", "my_snapshot_table")
}
