Using the AWS Command Line Interface

To create a vector search enabled MemoryDB cluster, you can use the MemoryDB create-cluster command by passing an immutable parameter group default.memorydb-redis7.search to enable the vector search capabilities.

aws memorydb create-cluster \
  --cluster-name <value> \
  --node-type <value> \
  --engine redis \
  --engine-version 7.1 \
  --num-shards 1 \
  --acl-name <value> \
  --parameter-group-name default.memorydb-redis7.search 
   

Optionally, you can also create a new parameter group to enable vector search as shown in the following example. You can learn more about parameter groups here.

aws memorydb create-parameter-group \
  --parameter-group-name my-search-parameter-group \
  --family memorydb_redis7

Next, update the parameter search-enabled to yes in the newly created parameter group.

aws memorydb update-parameter-group \
  --parameter-group-name my-search-parameter-group \
  --parameter-name-values "ParameterName=search-enabled,ParameterValue=yes"

You can now use this custom parameter group instead the of the default parameter group to enable vector search on your MemoryDB clusters.
