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
