Overview

IDManager maintains auto-incrementing ID sequences for LangChat’s Supabase tables. It handles concurrent inserts gracefully by using a retry-with-conflict-resolution strategy. This is an internal component — you don’t interact with it directly under normal use.

​
How it works

  1. On initialization, IDManager reads the current maximum ID from each table
  2. IDs are assigned from an in-memory counter
  3. When two concurrent requests try to insert with the same ID, the retry logic increments and retries automatically
  4. This avoids database sequences while maintaining consistent IDs

​
Constructor

​
Client
Supabase client instance.
​
int
default:"1"
Starting ID value for new tables.
​
int
default:"3"
Number of retry attempts on ID conflict before raising an error.

​
Methods

​
insert_with_retry()

Insert a record with automatic ID assignment and conflict retry.
Used internally by session.save_message() and metrics recording. You only need this if building a custom adapter.
