#fact

In Go (Golang), the boolean values true and false are untyped bool. This means that unlike many other programming languages, where boolean values have a specific type (e.g., bool), in Go, true and false are untyped. This design choice allows for greater flexibility in certain expressions and comparisons. The constants true and false are defined as untyped bool constants, and they can be used in various contexts without requiring explicit casting to a boolean type. This is a distinctive feature of Go's type system.

// true and false are the two untyped boolean values.
const (
  true  = 0 == 0 // Untyped bool.
  false = 0 != 0 // Untyped bool.
)

دیتابیس PostgreSQL قابلیت Full-Text search داره که خیلی وقت ها میتونه نیازمندی هارو پوشش بده و لازم نباشه سرویسی مثل elasticsearch رو بصورت مجزا استفاده کرد. چون نگهداری و مدیریت هر سرویس جدید هم هزینه نیروی انسانی داره و هم هزینه زمانی و انتقال دانش و کسب تجربه و غیره.

این مقاله قابلیت های دیتابیس PostgreSQL برای Full-Text search رو بیان میکنه

How is SQL Executed in DB?
➖➖➖➖➖➖➖➖
🕊 @gopher_academy

🔷️How Databases Execute SQL Statements?

🌏1. A SQL statement starts in a client program and gets sent over the network to the database server.

🌏2. When the database server receives the SQL statement, the relational engine starts processing it. First the command parser checks that the statement is valid. Then it converts the statement into a query tree, which is an internal data structure.

🌏3. The query optimizer looks at the query tree and figures out the most efficient way to execute the SQL statement, creating an execution plan.

🌏4. The execution plan gets passed to the query executor, which uses it to coordinate retrieving or changing the data as directed by the SQL statement. The executor interacts with the storage engine to access the data.

🌏5. The storage engine uses access methods, which are protocols for reading and writing data in the most efficient way for different operations.

🌏6. For reading data, the buffer manager checks if the required data is cached in memory and fetches it from disk if needed. This speeds up subsequent access.

🌏7. For writing data with inserts or updates, the transaction manager makes sure the changes happen atomically and maintain the database's integrity.

🌏8. At the same time, the lock manager applies locks so multiple transactions can happen simultaneously without conflict. This maintains isolation and consistency.
