# Number of Lookups
All -
Is there a limit on the number of lookups that can be created/used?
We have a large lookup (~600K rows) which can be split up into ~6K lookups of 100 rows each.
The advantage of splitting it up is that updates will be smaller/faster since all 600K rows need not be updated each time.
What is the performance implication of having so many 6K lookups?
Also, are lookups persisted somewhere either in deep storage or metadata (storage implication)? Will the lookups be available after cluster restart?
Thanks,
AR.
