[Nfd-dev] How to evict a specific item from the content store(nfd:cs)

[Junxiao Shi]

Hi Junjie

Cs::erase remains unimplemented because there's no use case for that, but it's going to come in a few months. Use the "Watch" button on https://redmine.named-data.net/issues/4318 to get notified, and be patient.

Since the above issue is still in design stage, it would be nice for you to describe your use case. Your answers will help the assignee to improve the design.
* Why do you want to erase specific Data?
* What's the calling process? NFD itself (which module?) or an application?
* Are you erasing one entry, or multiple entries under the same prefix?
* Does the calling process knows the exact Data name(s)?
You may answer these questions by REPLY-ALL to this email, or post them on Redmine.

Yours, Junxiao

Subject: [Nfd-dev] How to evict a specific item from the content store(nfd:cs)

Hello all,When I tried to use the erase( ) function to remove an item, I found
out that the method is not implemented.  I checked the code from the
documentation and found out that this is indeed the case. And I found that the eviction is happening in cache policy like cs-policy-lru.cpp when a new item is coming. 

So how am I supposed to evict a specific item from the Content Store? I mean evict a specific item by its name(prefix) in the cs.

Thanks,

JunjieXu
