dedicated to holding the value in the Interfa CE structure, so the assignment allocates a chunk of memory on the heap and records the pointer in the One-word slot. (There's obvious optimization when the value does fit in the slot; we'll get to that later.)
To check whether an interface value holds a particular type, as in the type switch above, the Go compiler generates cod e equivalent to the C expression s.tab->type to obtain the type pointer

Jsoniter performance is also very good, close to Easyjson, the key is no pre-compilation process, 100% compatible native library
Ffjson's serialization boost is not obvious, and deserialization is 1 time times higher
Codecjson is not much worse or worse than the original library.
Jsonparser is not suitable for this scenario, performance improvements are not obvious, and there is no deserialization

better understand the NoSQL database introduced in this book, it is essential to understand relational databases. So let's take a look at the history, classification, and features of relational databases.A Brief History of relational databases
In 1969, Edgar Frank Codd published an epoch paper that first proposed the concept of a relational data model. Unfortunately, the IBM Research Report published in the paper is only an internal publication of IBM, so the paper has a moderate response. In 1

Hardening therapy is suitable for patients with meniscus injury and frequent onset of symptoms. After 7 months of hardening therapy (12.5% dextran cod liver oil), the size of the cyst was significantly reduced in MRI. Although the results of this approach are acceptab

The so-calledRelational DatabaseIt is a database built on a relational model and uses mathematical concepts and methods such as set algebra to process data in the database. In the real world, the relationships between entities and entities are expressed by relational models. The relational model was first proposed by edugatde in 1970 and is in line with the twelve law of cod ". The twelve laws of codd may not be rememb
