Transitioning from VelocyPack Java Serialization to Jackson Serialization

Introduction:

In recent developments, it has come to light that the usage of VelocyPack Java serialization is now deprecated and will be removed in future driver versions. Instead, the recommended approach for serialization in both JSON and VPACK formats is to utilize Jackson serialization. This change brings a standardized and more widely adopted serialization mechanism to ensure better compatibility and performance. In this article, we will explore the implications of this deprecation and discuss how to configure your Java applications accordingly.

Understanding the Deprecation:

VelocyPack Java serialization, which was previously used for serialization and deserialization in ArangoDB, is being phased out in favor of Jackson serialization. The decision to deprecate VelocyPack is driven by the need for a more consistent and widely supported serialization solution across the ArangoDB ecosystem. By adopting Jackson serialization, developers can benefit from its robustness, extensive community support, and seamless integration with various frameworks and libraries.

Why Jackson Serialization?

Jackson is a popular Java-based library for working with JSON data. It provides a comprehensive set of features, including high-performance parsing and generation of JSON and VPACK formats, support for various data binding strategies, and advanced customization options. Jackson has gained widespread adoption in the Java community and is actively maintained, ensuring continuous improvements and bug fixes.

Benefits of Transitioning:

By transitioning from VelocyPack Java serialization to Jackson serialization, developers can reap several benefits:

1. Standardization: Jackson serialization is widely used across different Java frameworks, libraries, and databases. Embracing a standardized approach simplifies code maintenance, promotes interoperability, and facilitates the exchange of data between systems.
2. Performance: Jackson serialization is known for its high performance and efficiency. It employs efficient parsing and generation algorithms, resulting in faster data processing and reduced resource consumption.
3. Ecosystem Integration: Many popular Java frameworks and libraries have built-in support for Jackson, making it easier to seamlessly integrate serialization capabilities into existing projects. This ensures compatibility and simplifies the development process.

Configuring Jackson Serialization:

To configure Jackson serialization in your Java applications, the ArangoDB documentation provides detailed instructions and guidelines. It covers aspects such as adding the required dependencies to your project, configuring serialization settings, and handling custom serialization scenarios. Following these guidelines will help ensure a smooth transition to Jackson serialization.

Conclusion:

The deprecation of VelocyPack Java serialization in ArangoDB paves the way for the adoption of Jackson serialization, which offers a standardized and efficient approach to serialization and deserialization in Java applications. By embracing Jackson, developers can leverage its performance, ecosystem integration, and community support. It is recommended to refer to the official ArangoDB documentation for specific configuration instructions and stay updated with the latest changes to ensure a seamless transition from VelocyPack to Jackson serialization.
