Facing the same issue.
I am using periodic.iterate for creating nodes.
Within first statement am using apoc jdbc to get data from oracle, in the second statement am creating nodes with MERGE ON CREATE ON MATCH statement.
Apoc.periodic.itertate has the config params of
" {batchSize:10000, parallel:true,iterateList:true,concurrency:12,retries:5} "
Is there anything to change within config params ?
Thanks
