　　 In the node, the NUMA scheduler is the same as the O (1) scheduler. The dynamic load balancing on an idle processor is triggered by a clock interruption every 1 ms. It tries to find a high-load processor, and migrate the tasks on the processor to the idle processor. At a node with a heavy load, it is triggered every Ms. The Scheduler only searches for the processors in the current node. Only tasks that are not running can be moved from the Cache pool to other idle processors. 　　 If the load

1. The concept of iteratorsAn iterator is an abstract design concept. in design mode, the iterator pattern is defined as : Provides a way to sequentially access the individual elements contained in a container without exposing the container's internal organizational structure. Iterators can be seen as an object that behaves like a pointer, with iterators and pointers having the ability to dereference and access members.2. Related Types of iteratorsTypically, an iterator is used when using the ty

This article describes in detail a common basic knowledge about ORACLE locks. If you need it, you can check it out. ORACLE locks have the following modes:0: none1: null2: Row-S Row sharing (RS): Shared table lock, sub share3: Row-X exclusive (RX): used for Row modification, sub exclusive4: Share share lock (S): block other DML operations, Share5: S/Row-X shared Row exclusive (SRX): block other transaction operations, share/sub exclusive6: exclusive (X): used for independent access, exclusive 1.

atomic operations, bulk operations, transactional operations, multi-table operations, multi-table transactions, random traversal, and other features; Limit (default) Table name maximum 255B; (default) Key name maximum 255B; (default) The maximum value of the key is 16MB; (default) Single-table data 1TB; Support random traversal, do not support range traversal; Embedded database, no built-in C/s architecture; Installation go get -u gitee.com/johng/gfgo get -u gitee.c

This can lead to deadlocks because read and write transactions require periodic remapping of the data file, but only if the read-only transaction is open. Read and Write transactions To start a read-write thing, you can use the DB.Update() function: err := db.Update(func(tx *bolt.Tx) error { ... return nil}) Inside the closure, you have a consis
