node.js - Index optimizations for redundant data? -


i'm storing same tags: ['hello', 'world'] in multiple documents indexed.

does make sense use external mapping: tags: { hello: 1, world: 2 } resolved on client in favor of reduced index space , size of tags on disk?

essentially, client side compression mapping pulled static config file.

if storage space concern, using small field names , values whenever possible possible advantage. surmised reduce amount of data stored on disk. assuming client can handle mapping long term (and can handle maintenance of mappings) cannot see disadvantages.
