[jira] [Updated] (ATLAS-3057) Index Repair Tool: Add
JanusGraph-Specific Index Repair Tool
[ https://issues.apache.org/jira/browse/ATLAS-3057?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ashutosh Mestry updated ATLAS-3057:
-----------------------------------
Description:
*Background*
For Atlas version that uses _HBase_ and _Solr_, occasionally if Solr is down and entities get created, then there is no record of the created entities within Solr. Basic search does not indicate presence of such entities.
*Solution*
Index Repair Tool (which was present in branch-0.8) should be implemented for JanusGraph.
*Implementation Guidance*
* Create Java-based implementation rather than Groovy script that needs graphdb-specific shell to be installed.
* Use JanusGraph APIs for restore instead of custom per-vertex logic.
* Investigate possibility of using MapReduce for higher throughput.
