How conntrack and network namespaces works together?

cn flag

Is nf_conntrack respects network namespaces? Does it creates a separate table for each network namespace based on its sysctl limits, or does it share memory (and limits) between different network namespaces?

I've searched a lot, but wasn't able to find anything definitive.

I found a video [1] from 2015 with discussion of openvswitch and namespaces, and there was a rather strong confirmation that each namespace got a separate conntrack table with separate limits.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
