          Unregistering an observation listener blocks for no more than one second. If a pending onEvent() call does not complete by then a warning is logged and the listener will be unregistered without further waiting for the pending onEvent() call to complete. See OAK-1290 and JSR_333-74 for further information.

        See OAK-1459 introduced some differences in what events are dispatch for bulk operations (moving and deleting sub-trees):

      Binary streams

      In Jackrabbit 2 binary values were often (though not always) stored in or spooled into a file in the local file system, and methods like Value.getStream() would thus be backed by FileInputStream instances. As a result the available() method of the stream would typically return the full count of remaining bytes, regardless of whether the next read() call would block to wait for disk IO.

                                            In Jackrabbit 2.x, the following condition was interpreted as a LIKE condition:

                                            + +
                                            +

                                            Therefore, the query behaves exactly the same as if LIKE was used. In Oak, this is no longer the case, and such queries search for an exact path match.

                                            To take advantage of features that are available in full-text index implementations such as Apache Lucene and Apache Lucene Solr, so called native constraints are supported. Such constraints are passed directly to the full-text index. This is supported for both XPath and SQL-2. For XPath queries, the name of the function is rep:native, and for SQL-2, it is native. The first parameter is the index type (currently supported are solr and lucene). The second parameter is the native search query expression. For SQL-2, the selector name (if needed) is the first parameter, just before the language. Examples:

                                            + +
                                            +
                                            //*[rep:native('solr', 'name:(Hello OR World)')]
+
+select [jcr:path] from [nt:base] 
+where native('solr', 'name:(Hello OR World)')
+
+select [jcr:path] from [nt:base] as a 
+where native(a, 'solr', 'name:(Hello OR World)')
+
                                            +

                                            This also allows to use the Solr MoreLikeThis feature. An example query is:

                                            + +
                                            +
                                            select [jcr:path] from [nt:base] 
+where native('solr', 'mlt?q=id:UTF8TEST&mlt.fl=manu,cat&mlt.mindf=1&mlt.mintf=1')
+
                                            +

                                            If no full-text implementation is available, those queries will fail.

                                            To support the XPath query language, such queries are internally converted to SQL2.

                                            Every conversion is logged in debug level under the org.apache.jackrabbit.oak.query.QueryEngineImpl logger:

      Each transformed SQL2 query contains the original XPath query as a comment.

      +

      When converting from XPath to SQL-2, or conditions are automatically converted to union queries, so that indexes can be used for conditions of the form a = 'x' or b = 'y'.

      Query Processing

      Internally, the query engine uses a cost based query optimizer that asks all the available query indexes for the estimated cost to process the query. It then uses the index with the lowest cost.
