Erick Erickson commented on SOLR-11278:
---------------------------------------
bq: I'm guessing this will help but don't you think the bigger problem is why
can't replicate 10k documents ( 2 fields ) in 120 seconds? Perhaps we can add
some more logging to the test case like when the bootstrapping starts etc .
The evidence from a test I ran the other day (results in SOLR-11003) is that
these delays won't help. Or if they do let the test pass they just mask a more
fundamental problem. I changed one of the tests so if waitForTargetToSync
didn't return the proper number of docs I'd add one more document to the source
and call waitForTargetToSync again. Here's the important bits:
At the initial mismatch in waitForTargetToSync
target: 1901
source: 2000
After my new loop that adds a single doc to source then calls
waitForTargetToSync again I see counts of
target: 1902
source: 2001
Clearly my new doc is being indexed to the source and sent to the target so
it's not just a matter of the docs getting to the target but somehow not being
available to the currently-open searcher. They're just not on the target at all.
I'll instrument the tests a little more. It's strange that the difference is 99
and the packet size is 100, kind of feels like an off-by-one error.
