# Havasu Table Format Specification

Havasu is a spatial table format built on top of Apache Iceberg. Havasu

supports ACID transactions, schema evolution, and time travel on spatial

data including geometries and rasters. Havasu stores spatial data in

Apache Parquet format on cloud storage, which is very cost effective and

highly decoupled with computation.

This repository contains the Havasu specification, which is a formal

description of the Havasu table format. The specification is written in

Markdown and can be found in the [spec.md](spec.md) file.

A reader and writer implementation of Havasu table format specification

is available in [WherobotsDB](https://docs.wherobots.com/latest/tutorials/sedonadb/introduction/).

The detailed usage of WherobotsDB Havasu operations can be found on
