Hi All, Does anybody have more information on this?
Thanks, Seema From: Seema Datar <[email protected]<mailto:[email protected]>> Date: Thursday, November 7, 2013 10:49 AM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>>, "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: Question regarding life time of backend threads in PDNS Hi All, We have a use case where we use PDNS with 8 backend threads. We needed to save thread specific data in an mmap. However, I came across the following in PDNS documentation - PowerDNS may instantiate multiple instances of your backend, or destroy existing copies and instantiate new ones. Backend code should therefore be thread-safe with respect to its static data. Additionally, it is wise if instantiation is a fast operation, with the possible exception of the first construction. The questions I had are - 1. What is the lifetime of a backend thread? 2. How often does a thread get destroyed and a new thread get created? 3. Is there any interface available to do a cleanup before the thread ends? Thanks, Seema
