问题描述

我们的应用程序最近已升级到cassandra datastax驱动程序4.4.X.早期版本是3.3.升级后，我们注意到ex存在很多超时问题:

our application was recently upgraded to cassandra datastax driver 4.4.X. Earlier it was on version 3.3. After the upgrade we noticed quite a lot of timeout issues for ex:

1. 初始化查询超时
2. 会话查询超时
3. 控制连接超时..
4. 和其他超时参数在reference.conf中默认设置

以前，该参数曾经使用默认参数，但升级后，我们需要将其默认设置为>5秒.

Earlier this used to work with default parameter but after the upgrade we need to default this to > 5 seconds.

升级后，有人遇到过类似的问题吗?

Have any one faced similar issue after the upgrade?

推荐答案

您需要至少升级到Java驱动程序4.8(更好是4.9)-以前的超时过于激进(0.5秒)，在4.8中它已增加到5秒(通过修复 JAVA-2841 ).

You need to upgrade to at least Java driver 4.8 (better to 4.9) - previously timeouts were too aggressive (0.5 seconds), in 4.8 it was increased to 5 seconds (by fix of JAVA-2841).

或者您可以只覆盖 application.conf 文件中的相应参数.

Or you can just override corresponding parameters in the application.conf file.
