---------------------------------------
Summary: Improve delete robustness/performance
Key: ATLAS-906
URL: https://issues.apache.org/jira/browse/ATLAS-906
Project: Atlas
Issue Type: Task
Reporter: Jeffrey Hagelberg
Assignee: Jeffrey Hagelberg
Currently, the delete algorithm works by immediately performing the deletes and
property updates that are required. While this works, it is not very robust.
If there are errors found during the processing, we need to rely on Titan
properly rolling back the transaction. Given that titan does not guarantee
that the transactions are strictly ACID compliant, this may not always be a
safe thing to do. This task changes the algorithm to accumulate the changes to
be applied in a DeleteContext and only apply them once all of the processing
has been done. This will make the delete operation more robust. In addition,
it increases the chance that Titan (or whatever underlying graph database gets
used (see ATLAS-610) can batch the updates and perform them more efficiently
(and within a single atomic transaction).
