A question about recordDataTTL
Hi skywalking dev team:
Recently,I have meet a question that the recordDataTTL is not working, and I need you help.
History:
I hava set the recordDataTTL config equals 2(day),such as : "recordDataTTL: ${SW_CORE_RECORD_DATA_TTL:2} # Unit is day" when the skywalking init.
But now I want to keep the record data in es remain longer.Ant then I set recordDataTTL = 4 and restart the server,but it doesn't work,the 2 days before index will still be deleted.
Is anything wrong in my operation?
Wait for your help,Thanks a lot~

=========================
为了清晰表达，我用中文复述一下：
skywalking的开发团队好：
最近，我遇到了一个关于recordDataTTL 不生效的问题，需要寻求帮助
背景：
在我skywalking初始化的时候，我设置了recordDataTTL 为2 ，就像这样配置 "recordDataTTL: ${SW_CORE_RECORD_DATA_TTL:2} # Unit is day"。
但是现在我想让数据在es中保存时间更长一些，于是我设置了 recordDataTTL 等于4，并且重启了服务。过了一天后，我发现我在es中的索引还是保留了2天的，说明我的设置没生效。
我哪一步操作有问题吗？
期待您的帮助，非常感谢

There is no other mechanism to control this.
You have to recheck your deployment again.
BTW, you should recheck your versions comparing to change logs, there were
versions(some in 6.x) having TTL bugs.

Maybe you set the system environment in another process to override this
value? `SW_CORE_RECORD_DATA_TTL` is the name of system variable.
