Paulo Motta commented on CASSANDRA-10034:
-----------------------------------------
Wasn't able to reproduce the intermittency locally. My guess is that sometimes
{{toUnixTimestamp(now())}} is mapping to the same millisecond in the first and
second statements, so in the second statement {{b < toUnixTimestamp(now())}}
sometimes returns 0 entries:
{noformat}
INSERT INTO %s (a, b, c, d) VALUES (0, toUnixTimestamp(now()),
toTimestamp(now()), toTimestamp(now()))
SELECT * FROM %s WHERE a=0 AND b < toUnixTimestamp(now())
{noformat}
So I basically replaced {{b < toUnixTimestamp(now())}} in the second statement
by {{b <= toUnixTimestamp(now())}}, to guarantee at least one entry will be
returned in case {{toUnixTimestamp(now())}} maps to the same millisecond.
