Structure
Avro
Avro is a data serialization system that stores structured data in binary format. Avro was created to facilitate the exchange of data between systems in a secure and reliable manner. Avro provides a compact binary representation of complex data structures and supports schema evolution, which allows developers to evolve their schemas without breaking compatibility with existing applications. Avro’s main features include:
• Data types – Avro supports primitive types such as strings, integers, floats, booleans, bytes; maps; records; unions (for representing multiple possible values); and arrays.
• Schema Evolution – This feature allows developers to add new fields or change existing ones without having to break backward compatibility with older versions of their application code.
• Compression – Avro also supports compression formats such as Deflate and Snappy which can be used to reduce storage space requirements while still providing fast read/write performance when accessing large datasets.
• Metadata Support – Avro includes support for storing metadata along with each record in the form of key-value pairs which can be used by applications for additional information about the stored data or for custom indexing purposes.
CSV
CSV files are often employed for exchanging simple tabular datasets between different systems, given their straightforwardness in comparison to other formats such as XML or JSON, which necessitate more overhead when parsing them into usable objects within an application environment. Boasting simplicity and ease of use, CSV files allow users to define their own columns and field names within each row of comma-separated values, thus affording greater control over how the imported content will be displayed when imported into databases or spreadsheets. Key features include data types; schema evolution; compression support; and metadata storage.
• Flexibility – Users have full control over what column headers they use, allowing them to define whatever structure makes sense given their particular dataset rather than relying on predefined schemas like those found in Avro files
• Easy To Read – Unlike some other file formats like JSON or XML, which require specialized parsers before being readable by humans, CSV files are easily opened up using any basic text editor, allowing quick inspection of contents

Use Cases
Avro
Avro is an open-source data serialization system that can be used to store and transmit data in a compact binary format. Avro is beneficial for applications where small data size is essential, like in IoT devices or streaming services. Avro also supports schema evolution, which allows developers to make changes to existing schemas without breaking compatibility with older versions. This makes it ideal for use cases where the structure of the data may need to change over time, such as when dealing with rapidly changing datasets like those found in machine learning and artificial intelligence projects.
CSV
CSV (Comma Separated Values) files are widely used for exchanging tabular information between different systems and programs. CSV files have been around since the early days of computing, making them one of the most commonly used formats for exchanging tabular information today. They are simple yet effective at storing structured records in a human-readable form, making them easy to understand even by non-technical users. As such, they are often preferred over more complex formats like JSON or XML when working with smaller datasets that don’t require extensive processing capabilities or specialized toolsets on either end of transmission. CSV files can also be easily edited using any text editor or spreadsheet software application which makes them perfect for quickly updating records from remote sources without having to write custom code every time there is a change required
It is essential to determine which format will be most appropriate for your project, as Avro and CSV have distinct purposes. To help you decide, this article will provide recommendations on when each format should be used.
