Alex Ott updated CASSANDRA-15976:
---------------------------------
Description:
(tested on 4.0-beta1, but should be in all versions)
Right now, Cassandra incorrectly handles timestamps with less than 3 digits in
the milliseconds part. Timestamps (valid from the Java point of view (see
below output in Scala) are either rejected (if we have 1 digit only), or
incorrectly parsed when 2 digits are specified:
{noformat}
cqlsh> create table test.tm (id int primary key, tm timestamp);
cqlsh> insert into test.tm(id, tm) values (2, '2020-07-24T10:00:01.2Z');
InvalidRequest: Error from server: code=2200 [Invalid query] message="Unable to
coerce '2020-07-24T10:00:01.2Z' to a formatted date (long)"
cqlsh> insert into test.tm(id, tm) values (1, '2020-07-24T10:00:01.12Z');
cqlsh> select * from test.tm;
id | tm
----+---------------------------------
1 | 2020-07-24 10:00:01.012000+0000
(1 rows)
{noformat}
Checking with Instant:
{noformat}
scala> java.time.Instant.parse("2020-07-24T10:00:01.12Z")
res0: java.time.Instant = 2020-07-24T10:00:01.120Z
scala> java.time.Instant.parse("2020-07-24T10:00:01.2Z")
res1: java.time.Instant = 2020-07-24T10:00:01.200Z
{noformat}
Imho it should be fixed (Cc: [~aholmber])
