Tenant

A tenant is a logical component defined as a group of server/broker nodes with the same Helix tag.

In order to support multi-tenancy, Pinot has first-class support for tenants. Every table is associated with a server tenant and a broker tenant. This controls the nodes that will be used by this table as servers and brokers. This allows all tables belonging to a particular use case to be grouped under a single tenant name.

The concept of tenants is very important when the multiple use cases are using Pinot and there is a need to provide quotas or some sort of isolation across tenants. For example, consider we have two tables Table A and Table B in the same Pinot cluster.

We can configure Table A with server tenant Tenant A and Table B with server tenant Tenant B. We can tag some of the server nodes for Tenant A and some for Tenant B. This will ensure that segments of Table A only reside on servers tagged with Tenant A, and segment of Table B only reside on servers tagged with Tenant B. The same isolation can be achieved at the broker level, by configuring broker tenants to the tables.

No need to create separate clusters for every table or use case!

Tenant Config

This section contains 2 main fields broker and server , which decide the tenants used for the broker and server components of this table.

"tenants": {
  "broker": "brokerTenantName",
  "server": "serverTenantName"
}

In the above example:

  • The table will be served by brokers that have been tagged as brokerTenantName_BROKER in Helix.

  • If this were an offline table, the offline segments for the table will be hosted in Pinot servers tagged in Helix as serverTenantName_OFFLINE

  • If this were a real-time table, the real-time segments (both consuming as well as completed ones) will be hosted in pinot servers tagged in Helix as serverTenantName_REALTIME.

Creating a tenant

Broker tenant

Here's a sample broker tenant config. This will create a broker tenant sampleBrokerTenant by tagging 3 untagged broker nodes as sampleBrokerTenant_BROKER.

sample-broker-tenant.json
{
     "tenantRole" : "BROKER",
     "tenantName" : "sampleBrokerTenant",
     "numberOfInstances" : 3
}

To create this tenant use the following command. The creation will fail if number of untagged broker nodes is less than numberOfInstances.

bin/pinot-admin.sh AddTenant \
    -name sampleBrokerTenant 
    -role BROKER 
    -instanceCount 3 -exec
curl -i -X POST -H 'Content-Type: application/json' -d @sample-broker-tenant.json localhost:9000/tenants

Server tenant

Here's a sample server tenant config. This will create a server tenant sampleServerTenant by tagging 1 untagged server node as sampleServerTenant_OFFLINE and 1 untagged server node as sampleServerTenant_REALTIME.

sample-server-tenant.json
{
     "tenantRole" : "SERVER",
     "tenantName" : "sampleServerTenant",
     "offlineInstances" : 1,
     "realtimeInstances" : 1
}

To create this tenant use the following command. The creation will fail if number of untagged server nodes is less than offlineInstances + realtimeInstances.

bin/pinot-admin.sh AddTenant \
    -name sampleServerTenant \
    -role SERVER \
    -offlineInstanceCount 1 \
    -realtimeInstanceCount 1 -exec
curl -i -X POST -H 'Content-Type: application/json' -d @sample-server-tenant.json localhost:9000/tenants

This tenant is defined in the section of the table config.
