About data synchronization delay #102

Open lgy1027 opened 5 months ago

lgy1027 commented 5 months ago

Hello, I would like to ask you how to set the synchronization time when I mount a bucket to a pod and add or delete files on the page or directly in the pod. Because I tested it, the delay is still quite high. Does anyone know? What is the optimization direction?

Hi. What time do you mean? Do you mean the time which passes before the pod sees new files uploaded directly to S3 in other applications?

Yes, for example, if I create a file in a pod or upload a bucket file directly to S3 on a page, is there any file synchronization time?

There is no fixed delay, i.e. files are uploaded as quickly as possible, but writing doesn't wait for upload. You should call fsync if you want synchronous upload https://github.com/yandex-cloud/geesefs/?tab=readme-ov-file#fsync
