Summary: IGFS: Aggressively cache secondayr file systme metadata to minimize amount of direct FS calls.
Key: IGNITE-2819
URL: https://issues.apache.org/jira/browse/IGNITE-2819
Project: Ignite
Issue Type: Task
Components: IGFS
Affects Versions: 1.5.0.final
Reporter: Vladimir Ozerov
Priority: Critical
Fix For: 1.7
We call secondary file system inside TXes too often to get some metadata. Instead, when we access any file/dir in DUAL mode for the first time, we should cache all available metadata from the secondary file system, so that subsequent calls do not require it any more.
