Storage

📄️ Persistent Storage Rules

This section describes the rules that must be upheld for persistent storage.

📄️ B+ Tree

The B+ tree is used in almost all operators that require state management of rows, for instance in a join which must keep track of rows from the left input and right input.

📄️ Object State

The object state is the simplest type of state for an operator, it saves a C# object using JSON serialization to store it in persistent storage.
