Why it matters
This feature provides a tool to dump the Write-Ahead-Log of MergeTree tables, allowing users to inspect and analyze WAL data. It helps in debugging, data recovery scenarios, and better understanding of WAL internals for performance tuning and troubleshooting.How to use it
Users can enable and use the WAL dump tool to extract and view Write-Ahead-Log contents associated with MergeTree tables. Since WAL is experimental, users should enable WAL in the table settings and then invoke the dump tool via the appropriate CLI commands or utilities provided in the ClickHouse environment.
