Re: Question about opscenter Lifecycle Manager:

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

Re: Question about opscenter Lifecycle Manager:

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. Regards Mani On Aug 4, 2016 3:26 PM, "Yuan Fang" wrote: > Hello

Re: Merging cells in compaction / compression?

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 ? On Thu, Aug 4, 2016 at 10:08 PM, Michael Burman wrote: > Hi, > > No, I don't want to lose precision

Re: Merging cells in compaction / compression?

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,

Re: Merging cells in compaction / compression?

When you say merge cells, do you mean re-aggregating the data into courser time buckets? On Thu, Aug 4, 2016 at 5:59 AM Michael Burman wrote: > Hi, > > Considering the following example structure: > > CREATE TABLE data ( > metric text, > value double, > time timestamp, >

In the future you may find SASI indexes useful for indexing Cassandra data. Shameless blog post plug: http://rustyrazorblade.com/2016/02/cassandra-secondary-index-preview-1/ Deep technical dive: http://www.doanduyhai.com/blog/?p=2058 On Thu, Aug 4, 2016 at 11:45 AM Kevin Burton

Re: [Marketing Mail] Re: Memory leak and lockup on our 2.2.7 Cassandra cluster.

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 On Wed, Aug 3, 2016 at 1:54 PM, Ben Slater

Merging cells in compaction / compression?

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
