Can I Define a Custom Partition Key for GridDB Containers Using Node.js?

I want to distribute data across GridDB nodes based on a custom column (e.g., region_id) instead of relying on automatic partitioning

Use Case: All records with region_id = "East" should reside on Node 1, and region_id = "West" on Node 2

`const containerInfo = {

name: "regional_data",   

columns: [{ name: "region_id", type: "STRING" }],

};

store.putContainer(containerInfo, { partitionKey: "region_id" }); // this is hypothetical`

I have two Specific Questions

Does GridDB support custom partition keys via the Node.js API?

If not, what workarounds exist to control data distribution?

**Additional Context: **

The official Node.js client documentation does not mention partition key configuration.

  • The official GridDB Node.js client does not support setting a custom partition key like "region_id" — partitioning is handled automatically based on the container name hash. To control data distribution, your workaround would be to create separate containers per region, like regional_data_east, regional_data_west, and then route reads/writes manually in your app logic. Unfortunately, fine-grained partitioning by column isn't supported in the Node.js client at this time. Commented Sep 5 at 9:52
