I have recently started working on diameter protocol Sh interface. In TS 29.328, Section 6.1.1.1, it is given as

5. The HSS shall include the data pertinent to the requested Data Reference in the User-Data AVP and if the HSS supports the Notif-Eff feature,

I could not understand what is Notif-Eff feature. I searched for this term in RFC 3588 and RFC 6733, but could not find any relevant info.

Can you give me some idea on what is Notif-Eff feature ?

You can find Notif-Eff description in 3GPP TS 29.329 V9.2.0, section 7.1 - Version Control.

Please take a look there, but here is the quote from there:

This feature is applicable to the UDR / UDA and SNR / SNA command pairs. If both the HSS and the AS support this feature and if multiple subscriptions to notifications are associated with a Public User Identity, the HSS may combine the notifications for multiple Data References and Service Indications into a single notification message. Similarly the User Data Request / Answer will allow multiple data references and Service Indications and Identity Sets. The User Data Answer will be able to combine DataReference items resulting in the User Data Answer contents including a single XML document with the separable XML sections populated. Additionally, this feature allows concurrent subscriptions to different Identity Sets

Three areas for this:

Notif-Eff for RepositoryData implies - RepositoryData with multiple Service-Indications in the same message.

Notif-Eff for non-Transparent Data-reference implies multiple data-reference can be queried and answered back in a single request/response by Application Server/HSS .

This also refers to having multiple Identity-Set in a single data-reference e.g. IMSPublicIdentity 

And finally merging all the notifications and send them in a single message.
