cassandra-couchbase-transfer-plugin
This tool allows you to transfer data from Cassandra to Couchbase , just by doing some small configurations :) ##Configurations:
All the configurations can be done by setting the environment variables ###Couchbase Configuration:
| Configuration Name | Default Value | Description |
|---|---|---|
| COUCHBASE_URL | "localhost" | The hostname for the Couchbase. |
| COUCHBASE_BUCKETNAME | "foobar" | The bucket name to which data needs to be transferred. |
Cassandra Configuration:
| Configuration Name | Default Value | Description |
|---|---|---|
| CASSANDRA_URL | "localhost" | The hostname for the Cassandra. |
| CASSANDRA_PORT | 9042 | The port for the Cassandra. |
| CASSANDRA_KEYSPACENAME | "foobar" | The keyspace name for the Cassandra |
| CASSANDRA_TABLENAME | "testcouchbase" | The table name that needs to be transferred. |
| CASSANDRA_ID_FEILD_NAME | "id" | The field name that should be used as Couchbase Document Id, if the field name does not matches any column it gives a random id to the document. |
##Code in Action:
###Cassandra Side:
So this is how data looks on Cassandra Side:
###Couchbase Side:
Case 1: When id exists and same can be used as Couchbase Document Id.
Case 2: When id name does not exist and we need to assign Random id to Documents.
##How to Run the Cassandra-Couchbase Transfer plugin:
Steps to run the code are :
- Download the code from the repository.
- Configure the environment Variables according to the configuration.

export COUCHBASE_BUCKETNAME="foobar"
export CASSANDRA_URL="localhost"
export CASSANDRA_PORT=9042
export CASSANDRA_KEYSPACENAME="foobar"
export CASSANDRA_TABLENAME="testcouchbase"
export CASSANDRA_ID_FEILD_NAME="id"
export SPARK_URL="local[*]"
