Optimize the AEM Oak Lucene indexes to reduce reindexing time.
You can optimize the Oak Lucene indexes by fine-tuning the oak: QueryIndexDefinition
with properties such as includedPaths
, excludedPaths
, name
and indexPath
.
includedPaths
and excludedPaths
properties restrict what paths the index traverses when reindexing and which paths it listens to for index updates.name
and indexPath
properties make index logs easier to understand as they would tag the log messages with the path or name of the index. For example:30.01.2017 14:07:12.934 *DEBUG* pool-8-thread-2 org.apache.jackrabbit.oak.plugins.index.lucene.LuceneIndexEditor damassetlucene( /oak :index /damAssetLucene ) = Indexed 9000 nodes... |

Steps to optimize the indexes:
/oak:index
. includedPaths
and excludedPaths
properties should be multi-value String (String)
