> Key: IGNITE-17228
> URL: https://issues.apache.org/jira/browse/IGNITE-17228
> Project: Ignite
> Issue Type: Improvement
> Reporter: Kirill Tkalenko
> Assignee: Kirill Tkalenko
> Priority: Major
> Labels: ignite-3
> Fix For: 3.0.0-alpha6
>
>
> In 2.0, each checkpoint creates *start* and *end* markers on disk to perform
> a binary recovery if the node crashed in the middle of the checkpoint (there
> is no *end* market) which allows us to save the consistency of *index.bin*
> files (a special group cache file that stores all the indexes of this group).
> Since there is no WAL in 3.0 and indexes will be in each partition file,
> there is no need for checkpoint markers.
>
> What should be done:
> * Get rid of
> *org.apache.ignite.internal.pagememory.persistence.checkpoint.CheckpointMarkersStorage*;
> * Remove related tests;
> * If logical recovery is not yet supported, then we need to drop the node
> (throw exceptions at the start of the node) if we crashed in the middle of
> the checkpoint.
