   Hi,
   This is the first time we are setting up hudi with Multi writer,
   Below are my hudi config properties, I have set up
   HoodieWriteConfig.WRITE_CONCURRENCY_MODE.key()->"optimistic_concurrency_control",
   HoodieCompactionConfig.FAILED_WRITES_CLEANER_POLICY.key()->"LAZY",
   HoodieLockConfig.LOCK_ACQUIRE_NUM_RETRIES.key()->"3000",
   HoodieLockConfig.LOCK_ACQUIRE_CLIENT_NUM_RETRIES.key()->"1",
   HoodieLockConfig.LOCK_PROVIDER_CLASS_NAME.key()->"org.apache.hudi.aws.transaction.lock.DynamoDBBasedLockProvider",
   DynamoDbBasedLockConfig.DYNAMODB_LOCK_TABLE_NAME.key()->"hoodi_lock",
   DynamoDbBasedLockConfig.DYNAMODB_LOCK_PARTITION_KEY.key()->"lock",
   DynamoDbBasedLockConfig.DYNAMODB_LOCK_REGION.key()->"us-east-1",
   HoodieAWSConfig.AWS_ACCESS_KEY.key()->"XXX",
   HoodieAWSConfig.AWS_SECRET_KEY.key()->"XXX",
   HoodieAWSConfig.AWS_SESSION_TOKEN.key()->"XXXX",
   DynamoDbBasedLockConfig.DYNAMODB_ENDPOINT_URL.key()-> RegionUtils.getRegion("us-east-1").getServiceEndpoint(AmazonDynamoDB.ENDPOINT_PREFIX) //"dynamodb.us-east-1.amazonaws.com"
   
   I have created dynamodb table which will be used for locking, and partition key as lock
   Below are my questions,
   
   Is it mandatory to set AWS_ACCESS_KEY,AWS_SECRET_KEY ? - I dont want to set these keys
   Should we need to create Dynamodb table or Hudi will create it automatically? we create AWS resources with Cloudformation
   I am getting below exception while connecting to dynamodb table
   
   com.amazonaws.services.dynamodbv2.model.AmazonDynamoDBException: The provided key element does not match the schema
   Dynamodb table is created with partition key lock(String)
