Dynamic Aggregate Provider

Introduction

The aggregate provider configuration is key to accelerate the users queries. It is a compromise between memory usage and speed. The AI Optimizer can recommend a provider configuration tailored to your query history. It is now possible to use this recommendation (or any provider description) to change the provider configuration dynamically without restarting the application.

Adding a partial provider

First, define the partial provider:

final PartialProviderDefinition provider =
    new PartialProviderDefinition(
        "MyProvider",
        IAggregateProviderDefinition.BITMAP_PLUGIN_TYPE,
        List.of(LevelIdentifier.simple("id")),
        List.of("value.SUM"),
        PartialProviderFilters.noFilter(),
        new Properties(),
        null);

Then call the API to add the partial provider to the aggregate provider configuration:

DynamicAggregateProvider.updateAggregateProviders(
    manager, t -> t.addNewPartialAggregateProvider(CUBE, provider));

Removing a partial provider

To delete an existing provider, we simply use its name:

DynamicAggregateProvider.updateAggregateProviders(
    manager, t -> t.removePartialAggregateProvider(CUBE, "MyProvider"));

Batching operations

It is possible to add and remove several partial providers at once.

DynamicAggregateProvider.updateAggregateProviders(
    manager,
    t -> {
      t.addNewPartialAggregateProvider(CUBE, provider1)
          .addNewPartialAggregateProvider(CUBE, provider2);
    });

Querying during updates

When the aggregate provider configuration is updated, ongoing queries are not impacted: the previous version is still queryable.
