Usage

java -jar target/zkcopy-*-jar-with-dependencies.jar
    -Dsource="server:port/path" 
    -Ddestination="server:port/path" 
    -Dthreads=10
    -DremoveDeprecatedNodes=true
  • source - set source cluster address and root node to be copied
  • destination - set target cluster address and root node location where to copy data
  • threads - specify number of parallel workers. If latency is high, then increasing this number might significantly improve performance
  • DremoveDeprecatedNodes - set it to true to remove nodes that are present on target but missing on source
