Amrit Sarkar updated SOLR-11278:
--------------------------------
Attachment: SOLR-11278.patch
Ok here's what I am able to diagnose and have some questions and observations:
1. Bootstrap process runs in a seperate thread, then what happens we issue a
commit when BOOTSTRAPPING, replication / fetchIndex is taking place. Something
wrong? Solr core will reload when on the background index is getting copied.
2. I bumped up the time / sleep time b/w issuing CDCR and checking target
collection for numDocs to 7 seconds, and lowered documents from 10K to 2K,
since BOOTSTRAP will be issued anything above maxBatchSize: 1024.
3. The new patch uploaded successfully ran on my system, but it is not a
full-proof solution, just like: SOLR-10734, where we cannot agree on a batch /
thread count. It may fail for a seed in future or now.
[~varunthacker], requesting if you can apply the patch and verify whether the
tests are passing successfully.
