---------------------------------
Hi James,
About the version 3.5.0, I got unstable behavior with 10 threads. In first
full-import, I got successful import:
<lst name="statusMessages">
<str name="Total Requests made to DataSource">0</str>
<str name="Total Rows Fetched">1000</str>
<str name="Total Documents Skipped">0</str>
<str name="Full Dump Started">2012-04-16 14:12:08</str>
<str name="">Indexing completed. Added/Updated: 1000 documents. Deleted 0
documents.</str>
<str name="Committed">2012-04-16 14:13:21</str>

<str name="Total Documents Processed">1000</str>
<str name="Time taken ">0:1:12.875</str>
</lst>
But, in second, third full-import I got Indexing failed. Rolled back all
changes.
<lst name="statusMessages">
<str name="Time Elapsed">0:0:6.906</str>
<str name="Total Requests made to DataSource">0</str>
<str name="Total Rows Fetched">12</str>
<str name="Total Documents Processed">11</str>
<str name="Total Documents Skipped">0</str>
<str name="Full Dump Started">2012-04-16 14:15:38</str>
<str name="">Indexing failed. Rolled back all changes.</str>
<str name="Rolledback">2012-04-16 14:15:43</str>
</lst>
At catalina.out, I got:

In version 3.6.0 I did not get unstable behavior as obtained in version 3.5.0
with 10 threads.
In version 3.6.0 I tried without transformers:
<lst name="statusMessages">
<str name="Total Requests made to DataSource">0</str>
<str name="Total Rows Fetched">10000</str>
<str name="Total Documents Skipped">0</str>
<str name="Full Dump Started">2012-04-16 14:30:39</str>
<str name="">Indexing completed. Added/Updated: 10000 documents. Deleted 0
documents.</str>
<str name="Committed">2012-04-16 14:39:45</str>
<str name="Total Documents Processed">10000</str>
<str name="Time taken">0:9:5.719</str>
</lst>
In version 3.6.0, with just parent entity:
<lst name="statusMessages">
<str name="Total Requests made to DataSource">0</str>
<str name="Total Rows Fetched">10000</str>
<str name="Total Documents Skipped">0</str>
<str name="Full Dump Started">2012-04-16 14:42:49</str>
<str name="">Indexing completed. Added/Updated: 10000 documents. Deleted 0
documents.</str>
<str name="Committed">2012-04-16 14:49:05</str>
<str name="Total Documents Processed">10000</str>
<str name="Time taken">0:6:16.0</str>
</lst>
It's weird obtain 10000 documents processed. I only have 1000 records in the
database.
Thanks.
