Hi,
Considering the following example structure:
CREATE TABLE data (
metric text,
value double,
time timestamp,
PRIMARY KEY((metric), time)
) WITH CLUSTERING ORDER BY (time DESC)
The natural inserting order is metric, value, timestamp pairs, one metric/value
pair per second for example. That me
BTW. we think we tracked this down to using large partitions to implement
inverted indexes. C* just doesn't do a reasonable job at all with large
partitions so we're going to migrate this use case to using Elasticsearch

In the future you may find SASI indexes useful for indexing Cassandra data.

When you say merge cells, do you mean re-aggregating the data into courser
time buckets?

Hi,
No, I don't want to lose precision (if that's what you meant), but if you meant
just storing them in a larger bucket (which I could decompress either on client
side or server side). To clarify, it could be like:
04082016T230215.1234, value
04082016T230225.4321, value
04082016T230235.2563, v
Look like you're asking for some sort of ETL on your C* data, why not use
Spark to compress those data into blobs and use User-Defined-Function to
explode them when reading ?

Hi Yuan
Do you have OpsCenter Auth enabled? If yes, we are aware of this and have
fixed it internally. Please use Safari browser and this should work. On a
side note, I will DM you with more details.

Hi Mani,
Thanks so much Mani!
I did enabled OpsCenter Auth use username and password.
I previously used chrome.
After I changed to Safari, it seems better, at least, it did not fail
immediately.
After a couple of seconds, it shows:
Lifecycle Manager was unable to import Cassandra-Datastax-5 int
Hi Yuan,
