pub fn merge(inputs: &[PathBuf], output: &Path, dedup: bool) -> Result<usize>Expand description
Merges inputs into one multi-instance dump written to output.
When dedup is true (the default), records are decoded, de-duplicated, and re-packed into
compact shards. When false, the inputs’ sections are spliced through verbatim (a cheap raw
concat). Returns the number of distinct event schemas in the unified registry.
