Vineyard (v6d) is an innovative in-memory immutable data manager that offers **out-of-the-box
high-level** abstractions and **zero-copy in-memory** sharing for distributed data in various
big data tasks, such as graph analytics (e.g., `GraphScope`_), numerical computing
(e.g., `Mars`_), and machine learning.

What is vineyard
----------------

Vineyard is specifically designed to facilitate zero-copy data sharing among big data systems. To
illustrate this, let's consider a typical machine learning task of `time series prediction with LSTM`_.
This task can be broken down into several steps:

- First, we read the data from the file system as a ``pandas.DataFrame``.
- Next, we apply various preprocessing tasks, such as eliminating null values, to the dataframe.
- Once the data is preprocessed, we define the model and train it on the processed dataframe using PyTorch.
- Finally, we evaluate the performance of the model.

In a single-machine environment, pandas and PyTorch, despite being two distinct systems designed for
different tasks, can efficiently share data with minimal overhead. This is achieved through an
end-to-end process within a single Python script.

   :alt: Comparing the workflow with and without vineyard

What if the input data is too large to be processed on a single machine?

   As depicted on the left side of the figure, a common approach is to store the data as tables in
   a distributed file system (e.g., HDFS) and replace ``pandas`` with ETL processes using SQL over a
   big data system such as Hive and Spark. To share the data with PyTorch, the intermediate results are
   typically saved back as tables on HDFS. However, this can introduce challenges for developers.

1. For the same task, users must program for multiple systems (SQL & Python).

2. Data can be polymorphic. Non-relational data, such as tensors, dataframes, and graphs/networks
   (in `GraphScope`_) are becoming increasingly common. Tables and SQL may not be the most efficient
   way to store, exchange, or process them. Transforming the data from/to "tables" between different
   systems can result in significant overhead.

3. Saving/loading the data to/from external storage
   incurs substantial memory-copies and IO costs.

Vineyard addresses these issues by providing:

1. **In-memory** distributed data sharing in a **zero-copy** fashion to avoid
   introducing additional I/O costs by leveraging a shared memory manager derived from plasma.

2. Built-in **out-of-the-box high-level** abstractions to share distributed
   data with complex structures (e.g., distributed graphs)
   with minimal extra development cost, while eliminating transformation costs.

As depicted on the right side of the above figure, we demonstrate how to integrate
vineyard to address the task in a big data context.

First, we utilize `Mars`_ (a tensor-based unified framework for large-scale data
computation that scales Numpy, Pandas, and Scikit-learn) to preprocess the raw data,
similar to the single-machine solution, and store the preprocessed dataframe in vineyard.

|             |                                                                             |
|             |     import mars.dataframe as md                                             |
| distributed |     dataset = md.read_csv('hdfs://server/data_full', usecols=[1])           |
|             |     # after preprocessing, save the dataset to vineyard                     |
|             |     vineyard_distributed_tensor_id = dataset.to_vineyard()                  |
+-------------+-----------------------------------------------------------------------------+

Then, we modify the
training phase to get the preprocessed data from vineyard. Here vineyard makes
the sharing of distributed data between `Mars`_ and PyTorch just like a local
variable in the single machine solution.

+-------------+-----------------------------------------------------------------------------+
|             | .. code-block:: python                                                      |

|             |     data_X, data_Y = create_dataset(dataset)                                |
+-------------+-----------------------------------------------------------------------------+
|             | .. code-block:: python                                                      |
|             |                                                                             |
|             |     client = vineyard.connect(vineyard_ipc_socket)                          |
| distributed |     dataset = client.get(vineyard_distributed_tensor_id).local_partition()  |
|             |     data_X, data_Y = create_dataset(dataset)                                |
+-------------+-----------------------------------------------------------------------------+

Finally, we execute the training phase in a distributed manner across the cluster.

From this example, it is evident that with vineyard, the task in the big data context can
be addressed with only minor adjustments to the single-machine solution. Compared to
existing approaches, vineyard effectively eliminates I/O and transformation overheads.

Features
--------

Efficient In-Memory Immutable Data Sharing
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Vineyard serves as an in-memory immutable data manager, enabling efficient data
sharing across different systems via shared memory without additional overheads.
By eliminating serialization/deserialization and IO costs during data exchange
between systems, Vineyard significantly improves performance.

Out-of-the-Box High-Level Data Abstractions
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Computation frameworks often have their own data abstractions for high-level concepts.
For example, tensors can be represented as `torch.tensor`, `tf.Tensor`, `mxnet.ndarray`, etc.
Moreover, every `graph processing engine `_
has its unique graph structure representation.

The diversity of data abstractions complicates data sharing. Vineyard addresses this
issue by providing out-of-the-box high-level data abstractions over in-memory blobs,
using hierarchical metadata to describe objects. Various computation systems can
leverage these built-in high-level data abstractions to exchange data with other systems
in a computation pipeline concisely and efficiently.

Stream Pipelining for Enhanced Performance
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

A computation doesn't need to wait for all preceding results to arrive before starting
its work. Vineyard provides a stream as a special kind of immutable data for pipelining
scenarios. The preceding job can write immutable data chunk by chunk to Vineyard while
maintaining data structure semantics. The successor job reads shared-memory chunks from
Vineyard's stream without extra copy costs and triggers its work. This overlapping
reduces the overall processing time and memory consumption.

Versatile Drivers for Common Tasks
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Many big data analytical tasks involve numerous boilerplate routines that are unrelated
to the computation itself, such as various IO adapters, data partition strategies, and
migration jobs. Since data structure abstractions usually differ between systems, these
routines cannot be easily reused.

Vineyard provides common manipulation routines for immutable data as drivers.
In addition to sharing high-level data abstractions, Vineyard extends the capability
of data structures with drivers, enabling out-of-the-box reusable routines for the
boilerplate parts in computation jobs.

making it a natural fit for cloud-native computing. By embracing cloud-native big data
processing and Kubernetes, Vineyard enables efficient distributed data sharing in
cloud-native environments while leveraging the scaling and scheduling capabilities
of Kubernetes.

developed the Vineyard Operator. For more information, please refer to the `Vineyard
Operator`_ documentation.

FAQ
---

Vineyard shares many similarities with other open-source projects, yet it also has
distinct features. We often receive the following questions about Vineyard:

* Q: Can clients access the data while the stream is being filled?

  Sharing one piece of data among multiple clients is a target scenario for Vineyard,
  as the data stored in Vineyard is *immutable*. Multiple clients can safely consume
  the same piece of data through memory sharing, without incurring extra costs or
  additional memory usage from copying data back and forth.

* Q: How does Vineyard avoid serialization/deserialization between systems in different
  languages?

  Vineyard provides high-level data abstractions (e.g., ndarrays, dataframes) that can
  be naturally shared between different processes, eliminating the need for serialization
  and deserialization between systems in different languages.

abstract: >-
  Modern data analytics and AI jobs become increasingly complex and involve
  multiple tasks performed on specialized systems. Sharing of intermediate
  data between different systems is often a significant bottleneck in such
  jobs. When the intermediate data is large, it is mostly exchanged through
  files in standard formats (e.g., CSV and ORC), causing high I/O and
  (de)serialization overheads. To solve these problems, we develop Vineyard,
  a high-performance, extensible, and cloud-native object store, trying to
  provide an intuitive experience for users to share data across systems in
  complex real-life workflows. Since different systems usually work on data
  structures (e.g., dataframes, graphs, hashmaps) with similar interfaces,
  and their computation logic is often loosely-coupled with how such interfaces
  are implemented over specific memory layouts, it enables Vineyard to conduct
  data sharing efficiently at a high level via memory mapping and method sharing.
  Vineyard provides an IDL named VCDL to facilitate users to register their
  own intermediate data types into Vineyard such that objects of the registered
  types can then be efficiently shared across systems in a polyglot workflow.
  As a cloud-native system, Vineyard is designed to work closely with Kubernetes,
  as well as achieve fault-tolerance and high performance in production
  environments. Evaluations on real-life datasets and data analytics jobs show
  that the above optimizations of Vineyard can significantly improve the end-to-end
  performance of data analytics jobs, by reducing their data-sharing time up
  to 68.4x.
