Interesting design, low-level immutable DB engine as building block
From 2 comments
I am a big fan of this approach: Low-level, high-performance, immutable-by-default database engine as a building block, with bindings to multiple languages for easy application…
vtuulos on HNAmazing looking project! I've been daydreaming about using LMDB's memory mapping to provide a flexible low level db primitive for quite a while, figuring a combo of erlang like…

Commit message style is interesting
From 2 comments
I like how every commit message is formatted as a problem and a solution: https://github.com/PumpkinDB/PumpkinDB/commits/master
simonw on HNWhat an interesting commit message format.

Objections
Documentation is unclear about what it is and how to use it
From 3 comments
From what I see in the published documentation, it's way too early to make it "show HN". If I didn't know what event sourcing is, I couldn't make heads or tails of your daemon,…
dozzie on HNThanks. I read the entire "Documentation" page and still didn't feel confident that I understood what this really was. "Event sourcing" to me implies that it's generating events.
ams6110 on HNWell, its a fancy word. Thats basically what I took away from it. Also, I agree, read the whole doc and took way longer to understand what it does. Clearly, they are smart, but…

Unclear use case and advantages
From 1 comment

Disk space cost of never overwriting data; need for data removal
From 2 comments
I don't get this whole "never overwrite data" thing, including Datomic, for example. Isn't the disk space needed for these schemes enormous?
fiatjaf on HNI have reservations, too: it's important to be able to remove data even though disk is cheap. * Removing very old data is a reasonable hedge for user privacy. * Sometimes…

ziikutv on HNVery interesting! I think one thing that this would benefit from is a lot of usage examples, especially around pumpkinscript. I was reading recently about MUMPS and Caché and…

Support for Akka persistence
From 1 comment
Looks very interesting. I'd love to use it once it supports Akka persistence. Is this on the roadmap?

Questions
How does it compare to FoundationDB, Datomic or Berkeley DB?
From 3 comments
So basically something similar to FoundationDB?
mindcrash on HNIt seems to serve approximately the same purpose as Berkeley DB.
mtdewcmu on HNThis sounds like my (probably wrong/incomplete) understanding of Datomic?

Kafka and Samza

Where would I use this in place of, say, Kafka and Samza?
