Postgres的TOAST技术

【推荐阅读】微服务还能火多久?>>> 一、介绍 首先,Toast是一个名字缩写,全写是The OverSized Attribute Storage Technique,即超尺寸字段存储技术,顾名思义,是说超长字段在Postgres的一个存储方式。Postgres采用的存储默认是每个页面存储固定8Kb大小的数据,并且元组不允许跨页面存储,所以并不能直接存储大字段数据。Toast就是为此应运而生,它会将大字段值压缩或者分散为多个物理行来存储。对于用户来说完全不用关注这一技术实现,完全是透明的。 二、TOAST的存储方式 Postgres的部分类型数据支持toast,不是全部类型是因为有些字段类型是不会产生大字段数据的,完全没必要用到Toast技术(比如date,time,boolean等)。支持Toast的数据类型应当时变长的(variable-length),变长字段最多可选择32bit的列头(header),Toast占用两个变长的bit位来作为FLAG,故Toast的逻辑尺寸限制是(2^30-1)~1GB,当两个bit都是0是,这个数据类型的值就是非Toast的(untoasted)。当表中字段任何一个有Toast,那这个表都会有这一个相关联的Toast表,OID被存储在pg_class.reltoastrelid里面。超出的的数值将会被分割成chunks,并最多toast

微信小程序获取实时定位、选择位置名字(可解决因授权失败造成的问题)

若直接调用 wx.getLocation获 取定位,当第一次拒绝 或各种原因造成的失败,下一次无法调用,本文可解决此问题 1.app.json添加 "permission": { "scope.userLocation": { "desc": "地图选点需获取您的实时位置" } } 2.在根目录建utils/util.js const app = getApp() import Toast from '@vant/weapp/toast/toast'; var getLocation = function (that) { wx.getLocation({ type: 'gcj02', success: function (res) { // 经纬度 var latitude = res.latitude var longitude = res.longitude wx.chooseLocation({ success: function (res) { console.log(res.name); that.setData({ location: res.name, locationShow:false }) }, }) }, fail: function () { Toast.fail("授权失败"); } }) } module.exports = { getLocation

Android 用户界面---广播通知(Toast Notifications)

广播通知( Toast Notifications ) 广播通知是在窗口表面弹出的一个消息。它只填充消息展现需要的空间,并且用户当前的 Activity 依然可见和可交互。通知自动的渐入渐出,不接受交互事件。 下面图1显示一个例子是闹钟应用的广播通知,一旦闹钟被打开,就会在你设置的提醒时间显示一个广播通知。 图1 广播通知能够由 Activity 或 Service 创建和显示。如果你创建了一个源自 Service 的广播通知,它会显示当前有焦点的 Activity 的前面。 如要需要用户对通知做出响应,请考虑使用状态栏通知。 基础 首先,用 makeText() 方法实例化一个 Toast 对象。这个方法需要三个参数: 1. 应用程序的 Context 对象; 2. 要显示的文本消息; 3. 通知持续表示的时间。这个方法会返回一个合适的被实例化的 Toast 对象。你能够用 show() 方法显示广播通知,显示方法如下: Context context = getApplicationContext (); CharSequence text = "Hello toast!" ; int duration = Toast . LENGTH_SHORT ; Toast toast = Toast . makeText ( context , text , duration );
