Resource based slot range splitting in a distributed databases

So for learning purposes I was reading a few research papers on the topic of databases. I read through a few papers like gfs, cockroachdb, dynamodb, raft etc.. DynamoDb uses consistent hashing for the key distribution. It also uses virtual nodes for reducing the rebalancing problem when a node dies. So I had an idea of using the resource(disk, cpu, ram, network) of server to determine how much data/load it should handle. We can't determine the capacity of a server just with its hardware specs like ram & disk, if the latency is high or has frequent network issue then it makes that particular node not very reliable to hold the data. So incorporating the network details will help us get better resource scores of a node. Keys are mapped to slot using CRC16 and there will be a fixed number of slots 16384. Since I used a storage engine called pebble(similar to rocksdb) I was able to avoid the headache of writing the storage layer. I greatly underestimated the process of writing a database. So coming back to the topic I want to know if this resource based ranging splitting is already implemented and more information on it. I developed a architecture on this topic called irisdb and it implements this resource scores mechanism to determine which node to take the slot range to split. this is a learning project and I gladly accept any feedback I could get submitted by /u/wizard_zen [link] [留言]

Show HN: Unobin compiles Infrastructure as Code to one binary

Unobin is a language and compiler for Infrastructure as Code (IaC). IaC source is written and compiled to a binary, called a factory. The factory includes the runtime and all dependencies. To run a factory, pass it a configuration called a stack file that defines backend state and factory inputs. The stack file can only contain configuration, not arbitrary code. Factories can also display a UI in a browser showing progress (animated screenshot in the docs).
