Thomas Mueller commented on OAK-11478:
--------------------------------------
Usage:
{noformat}
java -cp oak-run-1.77-SNAPSHOT.jar
org.apache.jackrabbit.oak.index.indexer.document.flatfile.analysis.StatsBuilder
--fileName <treeStoreFileName> --treeStore
{noformat}
Where the tree store file name is eg. "r194f8dfc943-0-1.merged-tree.lz4"
Output: first, the progress is listed, in million nodes (with path). Then there
are different sections.
* NodeCount: number of nodes if more than one million.
* PropertyStats: for each property the count, approximate distinct values, avg
and max size.
* NodeTypeCount: number of nodes with the various primary types and mixins.
* BinarySize: references (in blob store) and embedded (small binaries), in GB,
per path
* BinarySizeHistogram: histogram of binary sizes (approximation) for references
and embedded
* TopLargestBinaries: top 10 largest binaries
* DistinctBinarySizeHistogram: histogram for approximate counts of binaries,
and approximate distinct counts
* DistinctBinarySize: approximate counts of binaries, and approximate distinct
counts
The following means there are around 4 GB of binary references, and 2 GB in
/content/dam and 2 GB in the version store. The DistinctBinarySize shows that
only ~2 GB are distinct binaries (multiple references can point to the same
binary):

> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: indexing
> Reporter: Thomas Mueller

> Priority: Major
>
> There is a statistics collector in oak-run-common that I use sometimes.
> It is currently missing support for tree stores.
> This issue is about adding support for this.
