go-nodetool
A golang library to manage Cassandra / Scylla clusters.
Dependencies
This library needs the Jolokia JMX<->HTTP bridge to work. It uses HTTP requests to the Jolokia server in order to read/write/exec Cassandra MBeans. To see how you can use Jolokia in Cassandra, check this guide.
Usage
go-nodetool performs administrative functions on a Cassandra / Scylla cluster. The commands available at the moment are:
| Command | Explanation |
|---|---|
Status |
information about the cluster |
Version |
version of the specific instance |
OperationMode |
operation mode of the specific instance |
Decommission |
decommission the specific instance |
import (
"net/url"
"github.com/yanniszark/go-nodetool/nodetool"
)
url, _ = url.Parse("127.0.0.1:8778/jolokia/")
nt := nodetool.NewFromURL(url)
nodeMap, err := nt.Status()
Contributing
Adding new commands is pretty straightforward. If you wish to extend this library with more commands, open an issue to request an enhancement or a PR to submit one. Use the existing commands as a guide on how to implement new ones and include unit tests.
Acknowledgement
A signification portion of code from this library comes from Jetstack Navigator. Modifications were made so that the library could be extended more easily.
