Re: Solr 6 CDCR does not work

Hi Adam,

maybe it's my poor English, but I'm confused.
I've taken Renault's quote as a hint to activate autocommit on the 
target cluster. Or at least doing manually frequent commits, to see the 
replicated documents.
Now you wrote disabling autocommit helps.

Could you please clarify this point?

Regards
Uwe
