ScyllaDB and Go

Using ScyllaDB with Go.

➡️ 👷🚧 Under Construction…


  • ScyllaDB
  • Golang
  • gocql
  • gocqlx


gocql is the driver to use ScyllaDB with Golang.


gocqlx is a wrapper for gocql that provides developer productivity without sacrificing performance.


Firstly, be sure to have both Docker, Docker Compose and Golang installed.

Git clone this repository:

git clone

Change directory into it:

cd scylladb-and-go

Then put Scylla cluster UP by using docker-compose:

# docker compose v1
sudo docker-compose -f docker-compose.yml up -d --build

# docker compose v2
sudo docker compose -f docker-compose.yml up -d --build

After some time (may take really some time, like 5min total) you’ll be able to have a Scylla cluster up and running. To verify that:

sudo docker exec -it scylla-node1 nodetool status

You should see something like:

Sometimes you may see some error like “Could not connect. Connection refused”. In order to change that, do:

sudo nano /etc/sysctl.conf

# Then add this line at the end of the file
fs.aio-max-nr = 1048576

# save it and to activate the config
sudo sysctl -p /etc/sysctl.conf

# after that, kill the containers and put them up again:
sudo docker-compose kill
sudo docker-compose rm -f
sudo docker-compose -f docker-compose.yml up -d --build

How to use the application

Once you have all the above section setted up, follow this one.


Using gocqlx to create our queries we have the following:

type T any

type IQueryBuilder[t T] interface {
	Insert(insertData *t) error
	Delete(dataToBeDeleted *t) error
	DeleteAllFromPartitioningKey(dataToBeDeleted *t) error
	Select(dataToGet *t) ([]t, error)
	Get(dataToGet *t) ([]t, error)
	SelectAll() ([]t, error)
  • Insert: will insert a new item into the database
  • Delete: will delete an item based on the Primary Key (Partitioning Key + Clustering Key)
  • DeleteAllFromPartitioningKey: will delete an item based on the Partitioning Key
  • Select: will return data based on the Partitioning Key
  • Get: will return data based on the Primary Key (PK + CK)
  • SelectAll: will return all data from table
