The evolution of the client for Ollama: from PostgreSQL to MongoDB

▤ Summary

This article explains how to migrate an Ollama chat client from PostgreSQL to MongoDB and why the switch can improve storage and retrieval patterns for LLM chat history. It compares PostgreSQL row storage and TOAST behavior with MongoDB's document model, BSON handling, and search capabilities. It also outlines frontend optimization techniques in React, including React.memo, useCallback, useMemo, and debounced localStorage writes. The piece ends by showing how GitIgnore parsing and prompt generation fit into the broader project selector workflow for the GitVerse project.
