DynamoDB for .net: Table name in data model - amazon-web-services

Question

I am using Dynamodb.net in my application.
I have the following code.
var creds = new BasicAWSCredentials(awsId, awsPassword);
var dynamoClient = new AmazonDynamoDBClient(creds,
awsDynamoDbRegion);
var context = new DynamoDBContext(dynamoClient);
List<ScanCondition> conditions = new List<ScanCondition>();
conditions.Add(new ScanCondition("Id", ScanOperator.Equal, myId));
var response = await context.ScanAsync<Data>(conditions).GetRemainingAsync();
return response;
My Data Model is as:
[DynamoDBTable("MyTable")]
public class Data
{
[DynamoDBHashKey]
public string Id{ get; set; }
public string Name { get; set; }
}
We are harcoding the table table name in our model "Data" as
[DynamoDBTable("MyTable")]
How can we not hardcode this. Is it possible to apply the table name in my actual code itself instead of giving in the model?
Thanks

Answer 1

Is OverrideTableName in DynamoDBOperationConfig what you are looking for ?
Description:
Property that indicates the table to save an object to overriding the
DynamoDBTable attribute declared for the type.
Example:
var x = await DbContext.LoadAsync<T>("hash", new DynamoDBOperationConfig {
OverrideTableName = "NewTableName",
IndexName = indexName
});
Also what you are looking for might be table prefix for every request of DbContext. It will append this prefix to every table. Useful if you want to isolate application specific tables like AppName-MyTable...
Example:
return new DynamoDBContextConfig
{
TableNamePrefix = "MyAppIdentifier",
ConsistentRead = false,
};

Answer 2

another option is to use different prefixes for the tables via
Amazon.DynamoDBv2.DataModel.DynamoDBContextConfig.TableNamePrefix
Property that directs DynamoDBContext to prefix all table names with a specific string. > If property is null or empty, no prefix is used and default table names are used.
https://docs.aws.amazon.com/sdkfornet/v3/apidocs/items/DynamoDBv2/TDynamoDBContextConfig.html
e.g.:
var credentials = new StoredProfileAWSCredentials("default");
var client = new AmazonDynamoDBClient(credentials, RegionEndpoint.USEast1);
var config = new DynamoDBContextConfig{
TableNamePrefix = "Test."
};
var ctx = new DynamoDBContext(client, config);
await ctx.SaveAsync(item);
