&gt; Hi,all:
&gt; 
&gt; ??????????????JoinedStreams:
&gt; ????????join??????????????????????????????????stream??key??????????????oom
&gt; ?????????????????????
&gt; ??key????????????????????
&gt; 
&gt; 
&gt; Right now, the join is being evaluated in memory so you need to ensure 
that the number
&gt; * of elements per key does not get too high. Otherwise the JVM might crash.
