Drop index on a large table RRS feed

  • Question

  • Hi All,

    I have a table size approx 1 TB  and millions of records, where one  non-clustered index is there size 255 GB, i wanted to drop that index, its a table on production environment. 

    I believe drop index on a huge table will take time and it may also lock table? whether dropping index lock table ?

    should i disable index and then drop index ?

  • Both disabling index or dropping it would not be that easy, yes locks would be applied if index is used. Simply do it when load is relatively very less. or during downtime
