Stefan Miklosovic commented on CASSANDRA-18861:
-----------------------------------------------
examples of the output:
{code}
cassandra@cqlsh> list USERS ;
name | super | datacenters
-----------+-------+-------------
cassandra | True | ALL
(1 rows, 12ms elapsed)
{code}
{code}
cassandra@cqlsh> update myks.mytb SET name = 'stefan' WHERE id = 1;
cassandra@cqlsh> update myks.mytb SET name = 'stefan' WHERE id = 1 IF exists;
[applied]
-----------
True
(36ms elapsed)
{code}
{code}
cassandra@cqlsh> BEGIN BATCH insert into myks.mytb (id, name) VALUES (1,
'joe'); APPLY BATCH;
cassandra@cqlsh> BEGIN BATCH insert into myks.mytb (id, name) VALUES (1, 'joe')
IF NOT EXISTS ; APPLY BATCH;
[applied] | id | name
-----------+----+------
False | 1 | joe
(8ms elapsed)
{code}
It is interesting to see that elapsed time is written only for CAS statements.
So if I do this when one statement is CAS and another is not:
{code}
cassandra@cqlsh> BEGIN BATCH insert into myks.mytb (id, name) VALUES (1, 'joe')
IF NOT EXISTS; insert into myks.mytb (id, name) VALUES (1, 'joe'); APPLY BATCH;
[applied] | id | name
-----------+----+------
False | 1 | joe
(9ms elapsed)
{code}
It will basically take into account not the time of whole batch but only of
statements which are CAS. So it will leave out another one from the elapsed
time computation.
> add time elapsed for simple CQL statement in the cql shell
