Some tips how to use {{converter}}:
Example of command line:
{code}
java -cp "lib/ignite-dev-utils-2.3.0-SNAPSHOT.jar:lib/ignite-indexing-2.3.0-SNAPSHOT.jar:lib/ignite-core-2.3.0-SNAPSHOT.jar:~/.m2/repository/com/h2database/h2/1.4.195/h2-1.4.195.jar" org.apache.ignite.development.utils.IgniteWalConverter 4096 ~/IdeaProjects/incubator-ignite/work/db/wal/127_0_0_1_47503 ~/IdeaProjects/incubator-ignite/work/db/wal/archive/127_0_0_1_47503 
{code}

You need to pass as argument:
1. Page size.
2. Path to WAL dir.
3. (Optional) Path to Archive WAL dir.

>             Project: Ignite
>          Issue Type: Bug
>          Components: persistence
>    Affects Versions: 2.1
>            Reporter: Eduard Shangareev
>            Assignee: Alexey Goncharuk
>             Fix For: 2.3
>
>
> Now there is no way to make wal visible or understandable without coding.
> I propose to write utility which would convert any given compatible WAL to textual form.
> Something like this:
> {code}
