the Impact of bitmap index

edited Jul 25, 2016 5:00AM in SQL Performance (MOSC) 8 commentsAnswered

Dear all,

I have a partitioned table with 8 Billions records, running on 11.2.0.4. Recently we changed 2 index type to Bitmap index, and this brought many performance enhancement, but unfortunately this effect the Update Operation on the table.

I know that the bitmap index may cause such an impact, and I'M wondering if there is a way to avoid that.
