…print
Reads histogram columns from Rezolus parquet recordings, reconstructs each
sample as `Histogram`, `SparseHistogram`, and `CumulativeROHistogram`, and
prints per-column and overall distribution statistics for the in-memory size
of each representation.
Usage:
cargo run --release --example rezolus_memory -- \
path/to/recording1.parquet path/to/recording2.parquet ...
Also bumps the crate to 1.1.1-alpha.0 per CLAUDE.md.

We didn't need this code to be actually in histogram |

Closing as superseded. While resolving the merge conflict with No work is lost: the example is on Generated by Claude Code |

Summary
Adds an example that measures the in-memory footprint of the
Histogram,SparseHistogram, andCumulativeROHistogramrepresentations for each row of everyList<UInt64>histogram column in one or more Rezolus parquet recordings. Reports per-column and overall distribution statistics (mean/min/max bytes, non-zero bucket counts, relative size).Also bumps the crate version to
1.1.1-alpha.0perCLAUDE.md.Usage
Results for the Rezolus sample recordings
