HbaseHbase具体原理可见前文记录Hbase 是面向oltp的数据库,通过LSM机制来平衡写和读的性能。但是要注意Hbase的思想是oltp,所以注定重点是写,要牺牲读,更适合多写少读的场景。但是实际情况下大多数读写场景通过Hbase就可以完全满足,为什么呢?因为LSM和其他一套组合拳也大量提升了读的性能最重要的就是LSM机制
为什么写快:
LSM机制本身的设计意义就是写数据直接先入内存中

# Android Flavor Overlap实现指南
## 概述
在Android开发中,flavor是一种很有用的功能,可以用于在同一个应用程序中创建多个变体。有时候我们需要让不同的flavor共享一些相同的资源或代码,这就是所谓的“flavor overlap”。在本文中,我将向你介绍如何实现Android Flavor Overlap。
## 流程
下面是实现Android Flav
# Python Polygon Overlap
## Introduction
When working with geometric shapes in Python, one common operation is determining whether two polygons overlap or intersect. This is a fundamental problem in
A rectangle is represented as a list [x1, y1, x2, y2], where (x1, y1) are the coordinates of its bottom-left corner, and (x2, y2) are the coordinates

## 图像拼接overlap的实现流程
### 1. 导入必要的库
首先,我们需要导入需要使用的库。在这个任务中,我们需要使用以下库:
- `cv2`:用于图像处理和拼接;
- `numpy`:用于数组和矩阵操作;
- `matplotlib`:用于可视化图像和结果。
```python
import cv2
import numpy as np
import matplotlib.pyplo

一、数据库OLAP和OLTP简单的介绍比较 1.OLTP:on-line transaction processing在线事务处理,应用在传统关系型数据库比较多,执行日常基本的事务处理,比如数据库记录的增删改查,如银行的一笔交易记录,就是一个典型的事务处理,强调数据库内存效率,强调内存各种指标的命令率,强调绑定变量,强调并发操作;OLTP有以这几个特点:实时性要求高;数据量不是很大;交易一般是确

HBase 2.x主要包含以下核心功能: 1、基于Procedure v2重新设计了HBase的Assignment Manager和核心管理流程。通过Procedure v2,HBase能保证各核心步骤的原子性,从设计上解决了分布式场景下多状态不一致的问题。 2、实现了In Memory Compaction功能。该功能将MemStore分成若干小数据块,将多个数据块在MemStore内部做Co

昨天和飞天舞者讨论静态类型语言和动态类型语言优劣比较的时候,说到Python没有重载机制的问题。后来想想挺有意思的,把思考的经过记录下来,欢迎拍砖。重载(overload)和覆盖(override),在C++,Java,C#等静态类型语言类型语言中,这两个概念同时存在。前者是为了让同一个函数名(方法名)匹配不同的参数(个数不同,类型不同);后者是为了实现多态,在相同名称的函数(方法)和参数,在不同
