Add the redact-info-log CLI and TOML option and inspector-owned logging helpers for errors, reflected values, stringers, and string slices. Redact configuration, queries and arguments, row values, repair SQL, chunk bounds, histogram bounds, and propagated query errors. Count rows through a redaction-aware query path and protect query errors shown in progress messages and reports. Preserve execution values and original errors, with regression coverage for both redaction settings.
Protect configuration, column metadata, and bucket decoding logs when log redaction is enabled. Preserve parsing behavior and the default logging behavior of other bucket-info callers. Cover both redaction modes and splitter diagnostic failpoints, and document the new option.

A rabbit logs a quiet clue,
With private bounds replaced by “?”,
The queries keep their values true,
While logs reveal a smaller view.
The buckets hop, the checks proceed,
Redacted fields are all they need.

dmlog.SetRedactLogbefore the earliest log or output call.
dmlog.SetRedactLog(cfg.RedactInfoLog)runs after the template, version, and parse-error paths. Those paths do not emit redacted fields, so the order is acceptable now. Keep this call before any new diagnostic logging that uses the redact helpers.

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.Redact the remaining chunk-index diagnostics.
This change redacts chunk bounds, ranges, and SQL. Several nearby logs still emit
zap.Any("chunk id", ...)orzap.Any("chunk index", ...). These log*chunk.CID, which holds only table, bucket, and chunk indices, not data values. They are not sensitive. ThecompareRowslog at Line 790 also writes the table name withzap.String. Schema and table names are identifiers, not row data.If the redaction policy covers only data values, no change is needed. If it also covers identifiers, redact those fields in the same way as the others. Confirm the intended policy.

What problem does this PR solve?
sync-diff-inspector can expose sensitive database values in SQL, query arguments, row data, chunk bounds, configuration, column metadata, and query errors. Operators need an option to hide these values in diagnostics.
Issue Number: close #12887
What is changed and how it works?
--redact-info-logand the top-level TOML settingredact-info-log, disabled by default. Explicit command-line values override the configuration file.?. Cover configuration dumps, SQL and arguments, row values, checkpoint and splitter bounds, histogram and column metadata, and error messages in logs, terminal output, and reports.pkg/dbutil, preserving existing behavior for callers that omit it, and preserve upstream bucket parsing behavior while protecting its diagnostics.Check List
Tests
Regression coverage checks redaction enabled and disabled, configuration loading, column metadata, query errors, malformed histogram bounds, normal and resumed timestamp decoding, parsing compatibility, and splitter diagnostic failpoints.
Validation passed:
Repository formatting was applied with
make fmtto the changed Go files.Questions
Will it cause performance regression or break compatibility?
The option defaults to false, preserving existing behavior. Enabling it masks sensitive diagnostic fields without changing database operations or data artifacts. Protected fields add a boolean check; no additional database queries are introduced, and no performance regression is expected.
Do you need to update user documentation, design documentation or monitoring documentation?
Yes. The README documents the command-line and TOML settings, default behavior, precedence, and the distinction between redacted diagnostics and data artifacts.
Release note
Summary by CodeRabbit
--redact-info-logorredact-info-log = true. Redaction is off by default, and the command-line setting takes precedence over the configuration file.?. Database queries, checkpoints, and generated fix SQL remain unchanged.
