Destination YugabyteCQL #

The extracted replicant-cli will be referred to as the $REPLICANT_HOME directory in the proceeding steps.

I. Set up Connection Configuration #

1. From $REPLICANT_HOME, navigate to the sample YugabyteSQL connection configuration file:

   vi conf/conn/yugabytecql.yaml
   

2. Make the necessary changes as follows:

   type: YUGABYTE_CQL
   
   #You can specify multiple Cassandra nodes using the format below:
   cassandra-nodes:
     node1: #Replace node1 with your node name
       host: 172.17.0.2 #Replace 172.17.0.2 with your node's host
       port: 9042 #Replace 9042 with your node's port
     node2: #Replace node2 with your node name
       host: 172.17.0.3 #Replace 172.17.0.3 with your node's host
       port: 9043 #Replace 9042 with your node's port    
   
   username: 'replicant' #Replace replicant with your username that connects to your Cassandra server
   password: 'Replicant#123' #Replace Replicant123#  with your user's password
   
   #read-consistency-level: LOCAL_QUORUM  
   #write-consistency-level: LOCAL_QUORUM
   
   max-connections: 30 #Specify the maximum number of connections replicant can open in YugabyteCQL
   

   • Allowed values for read-consistency-level and write-consistency-level are:
     • ANY
     • ONE
     • TWO
     • THREE
     • QUORUM
     • ALL
     • LOCAL_QUORUM (default value)
     • EACH_QUORUM
     • SERIAL
     • LOCAL_SERIAL
     • LOCAL_ONE

II. Set up Applier Configuration #

1. From $REPLICANT_HOME, naviagte to the sample YugabyteSQL applier configuration file:

   vi conf/dst/yugabytecql.yaml
   

2. Make the necessary changes as follows:

   snapshot:
     threads: 16 #Specify the maximum number of threads Replicant should use for writing to the target
   
     #If bulk-load is used, Replicant will use the native bulk-loading capabilities of the target database
     bulk-load:
       enable: true|false #Set to true if you want to enable bulk loading
       type: FILE|PIPE #Specify the type of bulk loading between FILE and PIPE
       serialize: true|false #Set to true if you want the generated files to be applied in serial/parallel fashion
   
       #For versions 20.09.14.3 and beyond
       native-load-configs: #Specify the user-provided LOAD configuration string which will be appended to the s3 specific LOAD SQL command
