Module bulk 

Prefix bulk ops + diagnostics (copy-prefix / delete-prefix / digest / diff / inspect). Prefix bulk ops + diagnostics: copy-prefix / delete-prefix (token-bucket rate limit, --dry-run), digest, diff, inspect.

Structs

RateLimiter

Token bucket: rate ops/second, starting EMPTY (strict pacing — a full-bucket start lets a small job burn its whole burst unthrottled, defeating the point of --rate for short sweeps). rate == 0 = unlimited.

Functions

run_copy_prefix

copy-prefix: SCAN src prefix, re-key under dst prefix via read+rebuild frames (the server has no COPY verb; TTL carried as absolute PEXPIREAT). Rate-limited per source key.

run_delete_prefix

delete-prefix: SCAN + UNLINK, rate-limited. Returns deleted count.

run_diff

diff: compare prefixes across two servers. Returns mismatching prefixes.

run_digest

digest <prefix> → (count, hex).

run_inspect

inspect <prefix>: sample keys, type distribution, sizes.
