kandi X-RAY | keyspace Summary
Keyspace is an encrypted name/value store which emphasizes a "least authority" philosophy for information sharing. All data is stored as encrypted name/value pairs, and data can be organized into "vaults" which each have independent encryption tokens and access control. Keyspace uses [capability-based security][capabilities] to manage access to vaults. Each capability takes the form of cryptographic tokens which are unique to a particular vault. Knowledge of these tokens is necessary and sufficient to gain access to a particular vault. Such an access scheme is known as "capabilities as keys" or "cryptographic capabilities". This approach provides secure sharing of access to vaults. This means there is no access control system (e.g. RBAC) other than the capability tokens themselves. Authorization is handled completely by whether or not you have the necessary cryptographic tokens to carry out a desired action. This straightforward approach leaves little room for error and reduces the entire attack surface to vulnerabilities in the cryptographic code or leaked capability tokens. Keyspace is built on [Moneta][moneta], an abstract API to many kinds of key/value stores including all ActiveRecord compatible databases, Redis, Riak, Cassandra, CouchDB, MongoDB, and many others. If there’s a key/value store you would like to persist to, Moneta probably supports it. Cryptography in Keyspace is handled by [RbNaCl][rbnacl], a Ruby wrapper to the [Networking and Cryptography][nacl] library by Daniel J. Bernstein. [capabilities]: [nacl]:

QUESTION
What is the recommended for cassandra (apache) 3.11.9 system_auth? need to be SimpleStrategy or NetworkTopologyStrategy? And with how much RF?
We have cassandra with 1 dc (2-3 AWS racks with EC2_snitch + dynamic_snitch disabled). Most queries running on consistency level local_one). Today our system_auth keyspace configured SimpleStrategy with RF 3. In a lot of queries, we are wasting time on (tracing):
ANSWER
Answered 2021-Jun-14 at 02:51I answered this question a while ago, which is similar: Replication Factor to use for system_auth
Due to issues that can happen with larger clusters which fluctuate in size, we now treat system_auth like we do any other keyspace. That is, we set system_auth's RF to 3 in each DC.
tl;dr;, if you're using NetworkTopologyStrategy on your non-system keyspaces, then you should also be using it for system_auth. Same with your RF; I'd always match the RF of system_auth with that of my "normal" keyspaces, as well.
No, the replication strategy and RF used on system_auth does not typically cause query latency. That is of course, unless any of the Security cache settings have been altered. 10 years of working with Cassandra, I've never had to change those: https://docs.datastax.com/en/security/5.1/security/secAuthCacheSettings.html
queries wasting time on (tracing): "Executing single-partition query on roles [ReadStage-X]"
This statement got me thinking: Are you tracing queries in cqlsh while logged in as the default cassandra user? That user does trigger some cqlsh operations to execute at QUORUM. Could also be that maybe the query consistency and connection consistency are set differently. Just a thought.
QUESTION
We have setup Redis with sentinel high availability using 3 nodes. Suppose fist node is master, when we reboot first node, failover happens and second node becomes master, until this point every thing is OK. But when fist node comes back it cannot sync with master and we saw that in its config no "masterauth" is set.
Here is the error log and Generated by CONFIG REWRITE config:

I am using Spring Boot 2.4.4 and Spring Data Cassandra dependency to connect to the Cassandra database. During the application startup, I am getting a DriverTimeout error (I am using VPN).
I have gone through all the Stack Overflow questions similar to this and none of them worked for me. I have cross-posted the same question on the Spring Boot official page here.
I used below configuration properties below -

QUESTION
If I go to my site I get data from database. First Load is slow and takes 1-2 seconds. But then it is fast like 10ms. Why is the first connection slow? It is only when I use cassandra driver.
...ANSWER
Answered 2021-Jun-07 at 03:12Reads from disk are always slower than reads from memory. When you query for the first time, Cassandra database reads from the disk which gets you a slow result. Second time Cassandra replies from the cached rows if caching is enabled, hence you get your results faster. PS : Please dont execute "select * from table" queries, they are kind of anti pattern in Cassandra.

Small question regarding how to connect to a Cassandra cluster that is SSL enabled please.
Currently, I am connecting to a Cassandra cluster that is not SSL enabled by doing the following, and it is working perfectly fine.

QUESTION
I need to run compaction on a very large table, 40% of disk space is free, but compaction take for a long time and fill up 100% of the disk then Cassandra process goes down, so I decided to run compaction by start and end token range, I select the ranges:
...ANSWER
Answered 2021-Jun-03 at 11:30It's better to use nodetool ring to find what exact ranges are owned by specific node, and then issue corresponding repair command.
But in reality it's better to use the Reaper tool - it does the calculations automatically, split owned ranges into sub-ranges, etc.

QUESTION
I want to stream a specific date format into a Cassandra datetime column.
My incoming date format is in the following date format:
...ANSWER
Answered 2021-May-18 at 14:31Cassandra supports only millisecond resolution for timestamp type. By default it's not allowed to write string into timestamp field, but Spark Connector having implicit transformations like this. And if you look into this source code, you'll see that it supports only parsing from timestamp with milliseconds.
So the solution would be to convert your timestamp column from string to Spark timestamp (only on Spark 3.x where support for microseconds resolution was added):

for a future poc i need to deploy an apache atlas 2.1 stack but i can't found the parameter for the cassandra backend connection in their documentation. if anyone got a link or had already made a implementation with password authentication.
this is my current config file if it can help.

Answered 2021-May-12 at 13:01You need to look into the JanusGraph documentation for that. According to it, there are two properties there: storage.username and storage.password that could be used prefixed by atlas.graph.storage.username: atlas.graph. & atlas.graph.storage.password
