[jira] [Commented] (SOLR-3360) Problem with DataImportHandler
multi-threaded
[ https://issues.apache.org/jira/browse/SOLR-3360?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13268400#comment-13268400 ]
James Dyer commented on SOLR-3360:
----------------------------------
Mikhail,
I'm looking over your "n+1" test and I don't see how it tests anything that isn't being covered in what I committed. These three tests...
testCachedThreadless_FullImport()
testCachedSingleThread_FullImport()
testCachedThread_FullImport()
...they all randomly select (1) is the parent entity cached?, (2) is the child entity cached (or is it going to do an n+1 select)?, and (3) how many threads (2-10)? (for the third test).
What is your version testing that this doesn't cover?
