I'm a retired data architect and C developer with 36 years of professional experience. In my opinion, this is not how you find an appropriate candidate. It would be better to ask s…

Yes, especially with early cleansing and transformation. When source semantics are dynamic, try to build recognizers rather than expect sources to obey some semantic agreement. The…

It is possible, but there are a lot of caveats. For example, how do you detect when a source's semantics change? This will break any cleansing or transforms done in the stream plat…

Yes. But, the trie implementation would need to somehow allocate mmap file address space. Depending on supported size of the trie, may require multiple mmap files. The addressing s…

Interesting. How would you use one of these implementations to persist a large trie beyond what physical memory can support?

Thanks for pointing that out. Instead of the endless cascade, just cascade once off of the first link. That way, there would never be more than two references to resolve and you st…

Instead of renaming the file, TagSpaces could create a symbolic link and preserve the original file name. All such links could be managed in a TagSpaces folder. > ln -s ../fluffy.j…

I enjoyed reading your story about building a DBMS. In it, you mention the importance of performance. So, I'm curious as to why you chose 'go' versus 'C'. Was the choice of 'go' a …

I'm developing a distributed temporal KV store in C. My motivation for developing the TKV is my interest in such questions as 'why' data changes and the effect it has on the 'syste…
