------------------------------------
Summary: IGFS: Optimize IgfsFileInfo format. (was: IGFS: Optimize metadata
format.)
> IGFS: Optimize IgfsFileInfo format.
> -----------------------------------
>
> Key: IGNITE-2813
> URL: https://issues.apache.org/jira/browse/IGNITE-2813
> Project: Ignite
> Issue Type: Task
> Components: IGFS
> Affects Versions: 1.5.0.final
> Reporter: Vladimir Ozerov
> Assignee: Vladimir Ozerov
> Fix For: 1.7
>
>
> *Problem*
> Currently our metadata appears to be too heavy.
> Short summary of {{IgfsFIleInfo}}:
> {{id}} - files and dirs
> {{len}} - only files
> {{blockSize}} - only files
> {{props}} - files and dirs
> {{lockId}} - only files
> {{affKey}} - only files
> {{fileMap}} - only files
> {{accessTime}} - files and dirs
> {{modificationTime}} - files and dirs
> {{listing}} - only dirs
> {{evictExclude}} - only files
> The same applies to {{IgfsListingEntry}}
> *Solution*
> 1) Split files and directories into separate classes. This will improve both
> performance and maintainability of {{IgfsFileInfo}} class.
> 2) Investigate whether we need {{IgfsListingEntry}} at all. It looks like we
> only need it for "listPaths" operation. Can we simply replace it with "String
> -> IgniteUuid" map?
