When I made a GSI projecting all keys, Can I apply a lower WCU limit for one side?

I think the write action, will cause same size of data to write.


Maybe it will replicate the data in a longer period, because it is eventually consistent.

Hi Hyron,

For questions like this, your best bet is to consult the AWS documentation.  Check out for the suggested WCU settings for a GSI.   If it’s lower than the original table, the index could lag behind in rebuilding.
