Multi-Datacenter Replication Reference: Per Bucket

To enable or disable replication per bucket, you can use the repl bucket property.

Some changes have occurred between 1.1 and 1.2.

These repl values are available in Riak Enterprise version 1.1 and above:

• `true) - Enable replication (realtime + fullsync)
• `false) - Disable replication (realtime + fullsync)

These option values are only available in Riak Enterprise version 1.2 and above:

• `realtime) - Replication only occurs in realtime for this bucket
• `fullsync) - Replication only occurs during a fullsync operation
• `both) - Replication occurs in realtime and during fullsync

Example of Disabling

curl -v -XPUT http://127.0.0.1:8098/buckets/my_bucket \
  -H "Content-Type: application/json" \
  -d '{"props":{"repl":false}}'

Example of Enabling

curl -v -XPUT http://127.0.0.1:8098/buckets/my_bucket \
  -H "Content-Type: application/json" \
  -d '{"props":{"repl":true}}'

How Bucket Properties Work in Riak KV

When using Multi-Datacenter Replication, each bucket’s write properties are derived from the bucket’s properties in the destination cluster. If the bucket doesn’t exist, the default properties of the destination cluster are used.

It’s important to note that this goes for properties such as backend. If the bucket doesn’t exist in the destination cluster, Riak will create it with the default backend and not with the backend used in the source cluster.
