Is it possible to connect to external instance of the Apache Cassandra (latest version)?
There have been some performance improvements in the version 1.2 that should help with my issue.
The startup time of our Cassandra database instance is more than 10 minutes (size is 50GB).
It is possible to connect to an external Cassandra cluster. Follow [1]

I want to migrate data. I use cassandra 3.11 and I want to compare Bulk with DS Bulk.
My problem is that when I use DS Bulk with cassandra community i have the follow error :
Incompatible cluster detected. Load functionality is only compatible with a DSE cluster.
The following nodes do not appear to be running DSE:
/127.0.0.1:9042
Operation LOAD_20190929-193810-582581 failed: Unable to load data to non DSE cluster.
DS Bulk is a proprietary tool built to work with their proprietary database. It's likely that the tool requires features not in Apache Cassandra or simply doesn't allow being run against it.
For Scylla monitoring, we need to configure Grafana but is it possible to integrate Cassandra Opscenter to Scylla?
TL;DR: No.
OpsCenter is a closed source product, which was not tested with Scylla. Part of it that uses Apache Cassandra CQL and JMX will probably work, while others might not.
In addition to the open source, Scylla monitoring stack (base on Prometheus and Grafana), ScyllaDB has its own close version product for cluster management named Scylla Manager.

I am using Cassandra 3.11 docker image for my application. But I am getting below. Can someone suggest a fix here
Enable Thrift server of Cassandra
The error means that JanusGraph can't connect to cassandra with thrift, So you have to enable thrift on cassandra.
Use the below command to enable thrift
nodetool enablethrift
First I had DataStax 3.7 installed and everything was fine but later I have downgraded to 2.2 and now I have reinstalled datastax 3.7 but i can't see it in services. I can open my datastax and connect to external clusters but I can't start my cassandra server and so Can't connect to local host.
How to solve this issue?
Thanks!
I've having some issues with my Cassandra cluster and I would like to install OpsCenter Community in order to debug what's going on.
I've found this and this pages talking about the compatibility between DataStax OpsCenter and Cassandra, but this don't list Cassandra 2.2.5 (actually I'm using DataStax Cassandra - dsc 22).
My question is: can I use DataStax OpsCenter (free / community version) within Cassandra 2.2.5? If not, there's an alternative?
No, the docs you cited indicate that OpsCenter doesn't support any cassandra greater than 2.1.x and the next version of opscenter (6.x) will only support Datastax Enterprise. I don't know of another visual front-end to cassandra at this time.
