The implementation details for the Merging Iterator in cckv.
This is the second post in a series documenting the development of cckv, a RocksDB-like KV storage engine written in C++20 for my experimental database sboxdb.
This post explains how MinIO implements erasure coding (EC) in practice—covering erasure sets, shard layout, read/write quorums, disk-full behavior, degraded operation, recovery (rebalance + heal), and how MinIO can safely scan very large object namespaces without collapsing under load.

Notes for the rust type categories
For rust fundamental types, the serde crate serializer and deserializer provide a reasonable type categories for grouping the complex types when serializing or deserializing a type.
The dominant speeds of hardware components are shifting.
...Notes for the reference in rust
Switching to Rust from C++ would encounter this question: does the reference sematics in rust is same as the C++?, Let’s describe it with an example.
...The content is COPIED from this awesome post as reference to myself.
As part of investigating the durability provided by cloud systems, I wanted to make sure I understood the basics.
...Let’s imagine we have an program that stores its state in a database, and we want other programs to do things when changes occur.
