> (copied from my last comment on PHOENIX-5090)
> Steps to reproduce (with Omid):
>  # {{!autocommit off}}
>  # {{create table test (pk1 integer not null, pk2 integer not null, pk3 integer not null,
v1 float, v2 float, v3 integer CONSTRAINT pk PRIMARY KEY (pk1, pk2, pk3)) DISABLE_WAL=true,
TRANSACTIONAL=true;}}
>  # {{upsert into test values(rand()*10000000, rand()*10000000, rand()*10000000, rand(),
rand(), rand()*1000000);}}
>  # {{upsert into test select rand()*10000000, rand()*10000000, rand()*10000000, rand(),
rand(), rand()*1000000 from test;}}
>  # {{select count\(*) from test; – this will cause uncommitted data to sent to the
server.}}
>  # Goto #4 a few time (until you inserted 131072 rows)
>  # {{!commit}}
> In a separate sqlline session just repeat after the commit was issued in the other session.
> * {{select count\(*) from test;}}
> You'll see that number will change until it finally settles.
