Chronicle Wire

Chronicle Wire is a java serialiser, that is able to read and write to different message formats such as JSON, YAML, CSV and raw binary data.

Pluggable Wire Implementation

Chronicle Wire abstracts away the implementation of the serialization to a pluggable Wire implementation. This means there is no need to change the code to change the encoding. The objects only need to describe what is to be serialized not how it should be serialized. It is developed with low latency in mind and reduced object creation this helps to deliver the highest possible performance.

Balanced Compactness

Chronicle Wire balances the compactness of the format without going to the extreme of compressing the data, which would use valuable CPU time. Storing the data in as few bytes as possible without sacrificing performance, for example, integers can be stored using stop bit encoding. 

Schema Changes

A key aim is to allow the schema to evolve over time. New schemas for an existing message can contain optional fields, fields in a different order, fields that are not expected. In other words, Chronicle Wire is able to read a message to a different type. It is also able to handle updating fixed-length fields and dynamic updates of Enums or objects passed-by-name.

Easy to Convert Format

Chronicle Wire is designed to make it easy to convert from one wire format to another. For example, you can use fixed-width binary data in memory for performance, and variable-width or text over the network. Different TCP connections could use different formats. It also supports hybrid wire formats. For example, you can have one format embedded in another.

High-Performance Java Serialisation to Different Formats

Java serialization is a popular mechanism where you are able to serialize and deserialize complex object graphs; for example where object A can contain a reference to object B, which in turn has a reference back to object A. The problem is that this rich functionality comes at a performance cost. However, if you do…

Did You Know You Can Create Mappers Without Creating Underlying Objects in Java?

As most Java developers know, putting values in a Java Map (like a HashMap) involves creating a large number of auxiliary objects under the covers. For example, a HashMap with int keys and long values might, for each entry, create a wrapped Integer, a wrapped Long object and a Node that holds the former values…
