Generally, an Object Store cannot offer the same performance or semantics as a local file system. More specifically: | |||
* random writes or appends to files require rewriting the entire object, optimized with multi-part upload copy | |||
* metadata operations such as listing directories have poor performance due to network latency | |||
* non-AWS providers may have eventual consistency so reads can temporarily yield stale data (AWS offers read-after-write consistency since Dec 2020) | |||
* no atomic renames of files or directories | |||
* no coordination between multiple clients mounting the same bucket | |||
* no hard links | |||
* inotify detects only local modifications, not external ones by other clients or tools | |||
