Distributed vs Decentralized

[edit]

On 6/11/17 I changed the header "decentralized" to "distributed" since Cassandra allows for a distributed database system [1]. In addition, the word decentralized has been popularized by the blockchain community and this might lead to confusion. Shahaed (talk) 13:13, 11 June 2018 (UTC)[reply]

Removing the worded like an advert banner. Whilst I can see that the content is a bit weak in places I don't see that it's not neutral — Preceding unsigned comment added by 185.69.144.191 (talk) 10:50, 11 July 2017 (UTC)[reply]

I corrected the link to the better explanation Elcidia (talk) 18:57, 10 March 2010 (UTC)[reply]

June 2009

[edit]

I've expanded the article a little, including a brief description of column families. I carefully skated over the difference between ordinary columns and supercolumns. (At the moment, the Google Code wiki has a better explanation of the data model than the wiki at apache.org.) Another important thing I left out is the Read Repair feature.

Given the lack of detail in the article, I've marked the article as a {{database-stub}}.

Corrections and expansions are very welcome. I suspect this will become a very significant project. 18:57, 10 March 2010 User:Elcidia

IBM Bluemail slides

[edit]

The link to IBM's research on using it for an email system links to Google Doc's PDF viewer rather than directly to the PDF. That seems odd. -- Ralph Corderoy (talk) 16:23, 18 January 2011 (UTC)[reply]

Latency

[edit]

The intro to this article is a mess. It says Cassandra enables low latency operations and then includes a quote saying latencies are high and that this somehow enables high throughput. It's not consistent and doesn't make sense. Telanis (talk) 05:00, 6 April 2016 (UTC)[reply]

I agree. The reality as I see it is this: Historically, as a result of its Log-structured_merge-tree, it has always had very low latency writes, potentially at the cost of higher read latency. However, there have been a number of optimizations over the intervening years that have brought read latency down to within accepted norms, so I'm not sure it's worth drawing any special attention to it at all. I believe the reference to latency in the first paragraph (which has probably been there since the early days of this article), was using low latency as a way of indicating Cassandra's suitability for transactional work loads (that used to be the way that language was used). I believe the reference to latency in the second paragraph is some combination of Wrong, and outdated. It should be relatively easy to find citations to support all of these assertions, and rewrite the entirely of the intro. I'd be willing to take a crack at this, but I might be too close to the project to be objective (though I do not think I could make it sound any more like a sales pitch if I tried :/ ).

Stable release

[edit]

The stable release is mentioned twice with different values (3.0 and 3.9). It needs to be fixed. — Preceding unsigned comment added by 98.234.159.92 (talk) 01:56, 12 January 2017 (UTC)[reply]

Proposed merge with Tombstone (data store)

[edit]

This should be a sub-section of the main article as Tombstones are inherent to Cassandra and not other NoSQLs Devopam (talk) 08:32, 18 June 2019 (UTC)[reply]

Disagree, this is untrue. To provide just a few counterexamples, Couchbase ref and OpenStack Swift ref also use tombstones; it's a broader distributed systems topic and not inherent to Cassandra. ␄ –Nucleosynth (t c) 13:55, 14 July 2019 (UTC)[reply]

Data model

[edit]

The description of the data model is confusing partly, I imagine, because it seems the terminology is not consistent with other types of database. A diagram would help a lot here. FreeFlow99 (talk) 14:05, 17 December 2023 (UTC)[reply]

Platforms

[edit]

I believe that Cassandra can run on AWS and on-prem, so guess it could run on GCP too. Is this right? What is the mechanism for scaling, ie how/what causes more containers/processors to spin up as necessary? FreeFlow99 (talk) 08:20, 3 September 2024 (UTC)[reply]
