Subject CDCR - cross data center replication
Date Fri, 26 Jan 2018 00:17:17 GMT
Hi all,

So for an initial CDCR setup documentation says bulk load should be performed first otherwise
CDCR won't keep up. By bulk load does that include an ETL process doing rapid atomic updates
one doc at a time (with multiple threads) so like 4K docs per minute assuming bandwidth between
DCs is actually good?

Also as a follow up question, in the documentation it says to do the bulk load first and sync
the data centers then turn on CDCR, what is recommended for the initial sync? A Solr backup
and restore?



CDCR is unlikely to be satisfactory for bulk-load situations where the update rate is high,
especially if the bandwidth between the Source and Target clusters is restricted. In this
scenario, the initial bulk load should be performed, the Source and Target data centers synchronized
and CDCR be utilized for incremental updates.
