Endpoint

Source: src/AWS/DMS/Endpoint.ts

An AWS Database Migration Service (DMS) endpoint — the source or target database of a replication. Endpoints are metadata-only (they store connection information, not data), so they are free and fast to create.

Endpoint: Creating Endpoints

MySQL Source Endpoint

const source = yield* Endpoint("Source", {
  endpointType: "source",
  engineName: "mysql",
  serverName: "source-db.example.com",
  port: 3306,
  username: "admin",
  password: Redacted.make("super-secret"),
  databaseName: "app",
});

S3 Target Endpoint

const target = yield* Endpoint("Target", {
  endpointType: "target",
  engineName: "s3",
  serviceAccessRoleArn: role.roleArn,
  s3Settings: {
    BucketName: bucket.bucketName,
    ServiceAccessRoleArn: role.roleArn,
  },
});

RebootReplicationInstance

Source: src/AWS/DMS/RebootReplicationInstance.ts

Runtime binding for dms:RebootReplicationInstance.

Bind this operation to a ReplicationInstance to reboot it (e.g. to recover a stuck migration or force a Multi-AZ failover with ForceFailover). Provide the implementation with Effect.provide(AWS.DMS.RebootReplicationInstanceHttp).

RebootReplicationInstance: Rebooting an Instance

// init — bind the operation to the instance
const reboot = yield* AWS.DMS.RebootReplicationInstance(instance);

// runtime
yield* reboot({ ForcePlannedFailover: true });

RefreshSchemas

Source: src/AWS/DMS/RefreshSchemas.ts

Runtime binding for dms:RefreshSchemas.

Bind this operation to a (ReplicationInstance, Endpoint) pair to (re)discover the schemas at the endpoint’s database using the instance’s compute. The refresh runs asynchronously — poll it with DescribeRefreshSchemasStatus, then list the result with DescribeSchemas. Provide the implementation with Effect.provide(AWS.DMS.RefreshSchemasHttp).

RefreshSchemas: Refreshing Schemas

// init — bind the operation to the instance + endpoint
const refreshSchemas = yield* AWS.DMS.RefreshSchemas(instance, source);

// runtime
const { RefreshSchemasStatus } = yield* refreshSchemas();

ReloadTables

Source: src/AWS/DMS/ReloadTables.ts

Runtime binding for dms:ReloadTables.

Bind this operation (account-level) to re-run the full load for specific tables of a running replication task — the standard remediation when DescribeTableStatistics reports table errors or validation failures. Provide the implementation with Effect.provide(AWS.DMS.ReloadTablesHttp).

ReloadTables: Monitoring Migration Progress

// init — account-level, no target resource
const reloadTables = yield* AWS.DMS.ReloadTables();

// runtime
yield* reloadTables({
  ReplicationTaskArn: taskArn,
  TablesToReload: [{ SchemaName: "public", TableName: "orders" }],
});

ReplicationInstance

Source: src/AWS/DMS/ReplicationInstance.ts

A DMS replication instance — the managed compute that runs migration and replication tasks. Provisioning takes several minutes and the instance is billed hourly while it exists, so create it only when a migration is running and destroy it promptly.

ReplicationInstance: Creating a Replication Instance

const instance = yield* ReplicationInstance("Migration", {
  replicationInstanceClass: "dms.t3.micro",
  allocatedStorage: 50,
  replicationSubnetGroupIdentifier: subnetGroup.replicationSubnetGroupIdentifier,
  publiclyAccessible: false,
});

ReplicationSubnetGroup

Source: src/AWS/DMS/ReplicationSubnetGroup.ts

A DMS replication subnet group — the set of VPC subnets a replication instance can be launched into. Must cover at least two Availability Zones. Free and fast to create.

ReplicationSubnetGroup: Creating a Subnet Group

const subnetGroup = yield* ReplicationSubnetGroup("Migration", {
  description: "DMS replication subnets",
  subnetIds: [subnetA.subnetId, subnetB.subnetId],
});

StartReplication

Source: src/AWS/DMS/StartReplication.ts

Runtime binding for dms:StartReplication.

Bind this operation (account-level) to start a DMS Serverless replication for a replication config by ARN — DMS provisions the required capacity and begins replicating. The serverless counterpart of StartReplicationTask. Provide the implementation with Effect.provide(AWS.DMS.StartReplicationHttp).

StartReplication: Orchestrating Serverless Replications

// init — account-level, no target resource
const startReplication = yield* AWS.DMS.StartReplication();

// runtime
const { Replication } = yield* startReplication({
  ReplicationConfigArn: configArn,
  StartReplicationType: "start-replication",
});

StartReplicationTask

Source: src/AWS/DMS/StartReplicationTask.ts

Runtime binding for dms:StartReplicationTask.

Bind this operation (account-level) to start, resume, or reload a replication task by ARN — the canonical DMS automation (a scheduled Function that starts CDC during business hours, an event-driven Function that kicks off a migration when upstream data lands). Provide the implementation with Effect.provide(AWS.DMS.StartReplicationTaskHttp).

StartReplicationTask: Orchestrating Replication Tasks

// init — account-level, no target resource
const startReplicationTask = yield* AWS.DMS.StartReplicationTask();

// runtime
const { ReplicationTask } = yield* startReplicationTask({
  ReplicationTaskArn: taskArn,
  StartReplicationTaskType: "start-replication",
});

StopReplication

Source: src/AWS/DMS/StopReplication.ts

Runtime binding for dms:StopReplication.

Bind this operation (account-level) to stop a running DMS Serverless replication by replication-config ARN (the stopped replication keeps its provisioned capacity). The serverless counterpart of StopReplicationTask. Provide the implementation with Effect.provide(AWS.DMS.StopReplicationHttp).

StopReplication: Orchestrating Serverless Replications

// init — account-level, no target resource
const stopReplication = yield* AWS.DMS.StopReplication();

// runtime
const { Replication } = yield* stopReplication({
  ReplicationConfigArn: configArn,
});

StopReplicationTask

Source: src/AWS/DMS/StopReplicationTask.ts

Runtime binding for dms:StopReplicationTask.

Bind this operation (account-level) to stop a running replication task by ARN — the other half of scheduled CDC windows and cost-control automation (pair with StartReplicationTask). Provide the implementation with Effect.provide(AWS.DMS.StopReplicationTaskHttp).

StopReplicationTask: Orchestrating Replication Tasks

// init — account-level, no target resource
const stopReplicationTask = yield* AWS.DMS.StopReplicationTask();

// runtime
const { ReplicationTask } = yield* stopReplicationTask({
  ReplicationTaskArn: taskArn,
});

TestConnection

Source: src/AWS/DMS/TestConnection.ts

Runtime binding for dms:TestConnection.

Bind this operation to a (ReplicationInstance, Endpoint) pair to initiate a connectivity test from the instance to the endpoint’s database. The test runs asynchronously — poll the result with DescribeConnections. Provide the implementation with Effect.provide(AWS.DMS.TestConnectionHttp).

TestConnection: Testing Connectivity

// init — bind the operation to the instance + endpoint
const testConnection = yield* AWS.DMS.TestConnection(instance, source);

// runtime
const { Connection } = yield* testConnection();
// Connection.Status === "testing" — poll DescribeConnections for the result
