Add OceanBase deployment guide

[cafe3310]

Background

Technically AWorld supports multiple databases including OceanBase, but currently lacks official deployment documentation. This guide will help users quickly set up OceanBase for AWorld.

---

Task For Reference

Create a deployment guide at docs/deployment/oceanbase_setup.md covering:

1. OceanBase Docker Setup

• Launch OceanBase CE using oceanbase/oceanbase-ce:latest
• Include Docker run command, port mappings, and connection details
• Provide verification steps (e.g., using mysql CLI)

2. Database Initialization

Create database and tables:

-- Create database
CREATE DATABASE aworld_db;
USE aworld_db;

-- Memory items table
CREATE TABLE IF NOT EXISTS aworld_memory_items (
    id VARCHAR(255) PRIMARY KEY,
    content TEXT NOT NULL,
    created_at VARCHAR(255) NOT NULL,
    updated_at VARCHAR(255) NOT NULL,
    memory_meta TEXT NOT NULL,
    tags TEXT NOT NULL,
    memory_type VARCHAR(50) NOT NULL,
    version INT NOT NULL DEFAULT 1,
    deleted TINYINT(1) NOT NULL DEFAULT 0
);

-- Memory histories table
CREATE TABLE IF NOT EXISTS aworld_memory_histories (
    memory_id VARCHAR(255) NOT NULL,
    history_id VARCHAR(255) NOT NULL,
    created_at VARCHAR(255) NOT NULL,
    PRIMARY KEY (memory_id, history_id),
    FOREIGN KEY (memory_id) REFERENCES aworld_memory_items (id),
    FOREIGN KEY (history_id) REFERENCES aworld_memory_items (id)
);

-- Indexes for performance
CREATE INDEX idx_memory_items_type ON aworld_memory_items (memory_type);
CREATE INDEX idx_memory_items_created ON aworld_memory_items (created_at);
CREATE INDEX idx_memory_items_deleted ON aworld_memory_items (deleted);

3. Python Connection Test

Provide a simple script using PyMySQL to:

• Connect to OceanBase
• Insert a test record
• Verify the insertion

4. Documentation Integration

• Ensure the file is discoverable in the docs navigation
• Add reference in relevant sections if needed

---

Reference

• Schema based on: aworld/memory/db/sqlite.py
• OceanBase docs: https://oceanbase.github.io/docs/
• Use PyMySQL or mysql-connector-python for connectivity

---

Definition of Done

• docs/deployment/oceanbase_setup.md created with all sections
• Docker setup instructions are clear and tested
• SQL commands work correctly in OceanBase
• Python verification script runs successfully
• Documentation is properly indexed
• End-to-end testing completed

---

Happy Hacking! This task is associated with "OceanBase Developer Carnival" event.
