hello guys, I met a problem when i using the solrcloud mode. When the solr instance run delta-import, it may take some time to be finished( my data source is mysql database). So during this time, the new added documents will loss, the deltaQuery, i use SUBDATE(${dih.last_index_time}, INTERVAL 2 MINUTE), let it run the delta-import 2 mins earlier than the last_index_time, if the delta-import's duration is 5 mins, it will loss the records at the first 3 mins. Our servers doesn't use solr cloud mode before, we deal with this issue is trying to rewrite dataimport.properties file, query the max(sys_time_stamp), which will help to record the max time stamp, and let the solr can run delta import standing by the time found in the file, of course, it will never miss documents. But now, we use solrcloud, the dataimport.properties is on the zookeeper, and we may have multiple collections for the same core.how can i update the dataimport.properties file now in collection now? Do you have any solution to help record the max(sys_time_stamp) in dataimport.properties, rather than using the time of delta-import start to run? Appreciate for any suggestions.
