求問(wèn)大神，對(duì)于mongodb以下幾個(gè)參數(shù)我的理解對(duì)不對(duì)？maxWaitTime=120000 是指已經(jīng)連接到mongodb，正在等待數(shù)據(jù)返回，這個(gè)等待的時(shí)間connectTimeout=10000 是指請(qǐng)求mongodb連接，還沒(méi)有連接上，正在等待連接的時(shí)間socketTimeout=0 是指已經(jīng)連接上了，正在傳輸數(shù)據(jù)，傳輸數(shù)據(jù)過(guò)程中會(huì)有耗時(shí)，這里就是等數(shù)據(jù)傳遞結(jié)束的等待時(shí)間

MongoDB Client驅(qū)動(dòng)設(shè)置中網(wǎng)絡(luò)相關(guān)的等待設(shè)置比較多，依次介紹如下：
1、Client找Server所需要等待的時(shí)間，在RS或者Shard環(huán)境下，Client需要找到它所需的Server
對(duì)應(yīng)的參數(shù)：ServerSelctionTimeOut
2、找到Server之后就需要建立Connection
1）每次都創(chuàng)建Connection，對(duì)應(yīng)的網(wǎng)絡(luò)等待的參數(shù)就是：connectTimeout 2）Connection pooling的話，從Connection Pool取得Connection，對(duì)應(yīng)的網(wǎng)絡(luò)等待的參數(shù)：maxWaitTime.
3、找到Connection之后，就有了Socket通信，在客戶端和MonogoDB的Socket通信過(guò)程中的網(wǎng)絡(luò)等待時(shí)間的參數(shù)就是：socketTimeout
供參考。
Love MongoDB！Have Fun！

Stackoverflow上有一個(gè)有140次贊的回答：How to configure MongoDB Java driver MongoOptions for production use?
connectTimeout. As the name suggest number of milliseconds the driver will wait before a connection attempt is aborted. Set timeout to something long (15-30 seconds) unless there's a realistic, expected chance this will be in the way of otherwise succesful connection attempts. Normally if a connection attempt takes longer than a couple of seconds your network infrastructure isn't capable of high throughput.
maxWaitTime. Number of ms a thread will wait for a connection to become available on the connection pool, and raises an exception if this does not happen in time. Keep default.
socketTimeout. Standard socket timeout value. Set to 60 seconds (60000).
