# Consider using JSON arrays instead of objects to transfer data

**[JOOQ](https://daily.dev/sources/jooq)** · 8 min read · 10 upvotes · 1 comments

## Summary

JSON arrays can provide 15-25% performance improvements over JSON objects for data serialization by enabling positional access instead of key-based lookups. While JSON objects offer better readability and debugging, arrays reduce overhead in both CPU processing and data transfer. The approach works particularly well in controlled environments where the client knows the exact structure and position of data fields, such as jOOQ's MULTISET operator implementation using SQL/JSON.

> When REST - it breaks the best practices - also on the HTTP level there is ZSTD/BROTLI etc.. Why bother? If using  xRPC - it's already using kind of efficent serialization... Why bother?
