Thanks for the reply.

Bihash I mean bounded index what Vpp supports.

Iam looking for the bucket level lock support. Currently Iam using hash
table shared by multiple process or multiple core/threads. So I have to
take the write lock by single core and then read lock by multiple cores to
read the value wrote in this hash table. Multiple readers are getting
blocked due to this. I want to avoid this to increase performance.

Let me know your thoughts on this.

Regards
Rajesh
