question: get the timestamp in epoch millis this shard was created concode_field_sep Shard MIN_SHARD concode_elem_sep long shardIndex concode_elem_sep boolean compacted concode_elem_sep Optional<DirectedEdge> shardEnd concode_elem_sep long createdTime concode_field_sep void setShardEnd concode_elem_sep int hashCode concode_elem_sep Optional<DirectedEdge> getShardEnd concode_elem_sep boolean equals concode_elem_sep long getShardIndex concode_elem_sep boolean isCompacted concode_elem_sep String toString concode_elem_sep boolean isMinShard concode_elem_sep int compareTo
target: long function ( ) { return createdTime ; }
