Alexey Goncharuk updated IGNITE-11749:
--------------------------------------
Ignite Flags: (was: Docs Required)
> Implement automatic pages history dump on CorruptedTreeException
> ----------------------------------------------------------------
>
> Key: IGNITE-11749
> URL: https://issues.apache.org/jira/browse/IGNITE-11749
> Project: Ignite
> Issue Type: Improvement
> Reporter: Alexey Goncharuk
> Priority: Major
>
> Currently, the only way to debug possible bugs in checkpointer/recovery
> mechanics is to manually parse WAL files after the corruption happened. This
> is not practical for several reasons. First, it requires manual actions which
> depend on the content of the exception. Second, it is not always possible to
> obtain WAL files (it may contain sensitive data).
> We need to add a mechanics which will dump all information required for
> primary analysis of the corruption to the exception handler. For example, if
> an exception happened when materializing a link {{0xabcd}} written on an
> index page {{0xdcba}}, we need to dump history of both pages changes,
> checkpoint records on the analysis interval. Possibly, we should include
> FreeList pages to which the aforementioned pages were included to.
