Erick Erickson updated SOLR-8263:
---------------------------------
Attachment: SOLR-6273-plus-8263-5x.patch
This patch is for 5x if we ever want to put CDCR in a 5x release since both
SOLR-6273 and SOLR-8263 should be committed. I'll put this patch on both JIRAs.
The patch should just be applied to 5x, no merging from trunk is necessary
there.
NOTE: The 5x patch was a little tricky to generate as dis-allowing local
loggers happened between times, but all that is incorporated here.
Many kudos to Renaud for all this work

> The current implementation of the tlog replication might interfere with the
> replay of the buffered updates. The current tlog replication works as follow:
> 1) Fetch the the tlog files from the master
> 2) reset the update log before switching the tlog directory
> 3) switch the tlog directory and re-initialise the update log with the new
> directory.
> Currently there is no logic to keep "buffered updates" while resetting and
> reinitializing the update log.
