Manage Indexes for Zero-Downtime Updates

Use aliases to swap indexes without application changes.

Correct: Use aliases for production indexes.

# Create versioned index
FT.CREATE idx:products_v2 ON HASH PREFIX 1 product:
    SCHEMA
        name TEXT
        category TAG SORTABLE
        price NUMERIC SORTABLE

# Point alias to new index
FT.ALIASADD products idx:products_v2

# Application queries use alias
FT.SEARCH products "@category:{electronics}"

# Later, swap to new version
FT.ALIASUPDATE products idx:products_v3

Useful management commands:

# Check index info
FT.INFO idx:products

# Drop and recreate (non-blocking)
FT.DROPINDEX idx:products
FT.CREATE idx:products ...

# List all indexes
FT._LIST
