Provisioning strategies

Provisioning strategies control whether to create a new index or reuse an existing one when the channel starts.

public interface IIndexProvisioningStrategy
{
    Task<string> ProvisionAsync(ProvisioningContext context, CancellationToken ctx = default);
    string Provision(ProvisioningContext context);
}
		

Always creates a new index. This is the default when no content hashing is available.

Compares the content hash of the channel's mappings/settings with existing indices. If a matching index exists, it reuses it instead of creating a new one. This avoids creating duplicate indices when the schema hasn't changed.

Auto-selected when ElasticsearchTypeContext.GetContentHash is available.
