------------------------------------
Summary: Index merge: merge aggregation definitions
Key: OAK-11735
URL: https://issues.apache.org/jira/browse/OAK-11735
Project: Jackrabbit Oak
Issue Type: Improvement
Reporter: Thomas Mueller
Assignee: Thomas Mueller
The ["aggregates"
definitions|https://jackrabbit.apache.org/oak/docs/query/lucene.html#aggregation]
are not currently merged. If both the product as well as the customization
have new entries, then they will conflict, because they have the same node name
(eg. include11). (JCR does not support arrays of objects like JSON, that's why
we have these names).
To resolve this, the newly added customizations need to be renamed. Eg.
{noformat}
ancestor:
/oak:index/acme-1
aggregates/asset/include1/a
customization:
/oak:index/acme-1-custom-2
aggregates/asset/include1/a
aggregates/asset/include2/xyz <== conflict due to name "include2"
new product:
/oak:index/acme-2
aggregates/asset/include1/a
aggregates/asset/include2/b <== conflict due to name "include2"
expected:
/oak:index/acme-2
aggregates/asset/include1/a
aggregates/asset/include2/b <== copy from product
aggregates/asset/include3/xyz <== rename "include2" -> "include3"
{noformat}
