Pass in table name via context or environment variable

[ujjwal]

@DynamoDBTable(tableName = "someTableName")

Is there a way to pass the tableName as a parameter?

Yes via AWS functionality itself:

@Configuration
@EnableDynamoDBRepositories(dynamoDBMapperConfigRef = "dynamoDBMapperConfig",
    basePackages = "com.acme.repository")
public class DynamoDBConfig {
    @Bean
    public DynamoDBMapperConfig dynamoDBMapperConfig() {
        DynamoDBMapperConfig.Builder builder = new DynamoDBMapperConfig.Builder();
        builder.setTableNameResolver(new YourCustomTableNameResolverHere());
        return builder.build();
    }
}

If you just wan to prefix table names (to separate environments), there are ready-to go classes:

builder.setTableOverride(
        com.amazonaws.services.dynamodbv2.datamodeling.DynamoDBMapperConfig.TableNameOverride.withTableNamePrefix("dev"));

Not sure maybe it is the bug in AWS lib. I'm using "aws-java-sdk-bom" 1.11.175. The problem is when I use my own DynamoDBMapperConfig, then config.getTypeConverterFactory() is the null and internal error thrown.
I have added: builder.setTypeConverterFactory(DynamoDBMapperConfig.DEFAULT.getTypeConverterFactory());
