Summary: Move binary metadata to PDS storage folder
Key: IGNITE-12994
URL: https://issues.apache.org/jira/browse/IGNITE-12994
Project: Ignite
Issue Type: Improvement
Reporter: Semyon Danilov
Assignee: Semyon Danilov
Move binary metadata to PDS storage folder
Motivation: On K8s deployment disk that is attached to container can not be
accessible from other containers or outside of K8s. In case if support will
need to drop persistence except data, there will be no way to recover due to
binary metadata is required to process PDS files
Current PDS files that are required to restore data:
* {WORK_DIR}/db/\{nodeId}
* {WORK_DIR}/db/wal/\{nodeId}
* {WORK_DIR}/db/wal/archive/\{nodeId}
Proposed implementation:
If binary meta is already located at \{WORK_DIR}/db then start using it
If no metadata been detected via new path then:
# Check previous location
# Copy metadata files to a new location
# Delete previous binary metadata
