It actually supports function now in JSON format.
For anyone who want to insert a current timestamp by JSON format, here is the
query:
{code}
The ts column should be timestamp.
insert into test JSON '{"id":2,"ts":"now"}';

It actually supports function "now" in JSON format. Just remove the parenthesis.
For anyone who want to insert a current timestamp by JSON format, here is the
query:
{code}
The ts column should be timestamp.
insert into test JSON '{"id":2,"ts":"now"}';

Now select one record based on primary key, we got all three records.

AND speculative_retry = '99PERCENTILE';
CREATE INDEX test0_b_idx ON ops.test0 (b);
{code}
was:
