🏗️ Database Schema Evolution
BEFORE: String-based (Not Type-Safe)
CREATE TABLE ensemble_predictions (
id UUID PRIMARY KEY,
ensemble_action TEXT, -- ❌ "BUY", "SELL", "HOLD" (string)
-- ...
);
-- String validation at runtime
SELECT * FROM ensemble_predictions
WHERE ensemble_action = 'BUY'; -- ❌ Typo-prone ("buy" vs "BUY")
AFTER: Enum-based (Type-Safe)
-- Migration: Add 'hold' to order_side enum
ALTER TYPE order_side ADD VALUE 'hold';
CREATE TABLE ensemble_predictions (
id UUID PRIMARY KEY,
ensemble_action order_side, -- ✅ Enum: {buy, sell, hold}
-- ...
);
-- Type-safe enum validation at database level
SELECT * FROM ensemble_predictions
