FOI: some stats after extracting metadata (no content metadata)

[yarikoptic]

D'oh (for myself): this repo (dataset) is pure git, not git-annex

extracted all metadata (without any content - just base core, datalad 0.12.5.dev19), and it went into git.

FWIW some stats

• totals: 5.8GB of .datalad/metadata
• .git/objects is 1.6GB
• majority is ds-* files (~4.9GB). They didn't get .xz'ed
• majority of ds-* size seems to be due to annex.filename which is a list of lists of filenames.
• those ds-* compress ~8 times if we do xz them
