[jira] [Commented] (OAK-2050) Query engine: disable or restrict built-in full-text engine

["Alex Parvulescu (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OAK-2050?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14112058#comment-14112058 ] 

Alex Parvulescu commented on OAK-2050:
--------------------------------------

One of the issue with the way FullTextSearchImpl works is that the FullTextSearchImpl will call #getValue(STRING) on a property without checking the type first, and if that's an _external binary_ then there's trouble for the SegmentMK, you'll get a cryptic error:
bq. java.lang.IllegalStateException: String is too long: 2318847354967717297

The code needs to take into account the impact of reading binaries as strings.

> There is a built-in full-text engine that is used for full-text queries if no full-text index (Lucene, Solr) is available.
> This built-in engine tries to load binaries in memory, which can result in out-of-memory.
> We either need a way to disable this built-in mechanism (in which case the query engine would throw an exception for full-text queries), and / or change the built-in mechanism so it doesn't result in out-of-memory.
