Hi John,
The general answer: Each cell in a CQL table has a corresponding timestamp
which is taken from the clock on the Cassandra node that orchestrates the
write. When you are reading from a Cassandra cluster the node that
coordinates the read will compare the timestamps of the values it fetches
Suppose I have the following schema,
CREATE TABLE foo (
id text,
time timeuuid,
prop1 text,
PRIMARY KEY (id, time)
)
WITHCLUSTERING ORDER BY (time ASC);
And I have two clients who execute quorum writes, e.g.,
// client 1
INSERT INTO FOO (id, time, prop1) VALUES ('test', , 'bar');
