/**
 * Runtime binding for the `CreateIndex` operation scoped to one collection
 * (IAM action `aoss:APIAccessAll` on the collection ARN).
 *
 * Creates an index in the bound {@link Collection} from inside a function
 * runtime — the control-plane path for the multi-tenant pattern where each
 * tenant gets its own (vector) index. The calling principal must also be
 * granted `aoss:CreateIndex` on the index pattern by a data
 * {@link AccessPolicy}. Provide the implementation with
 * `Effect.provide(AWS.OpenSearchServerless.CreateIndexHttp)`.
 * ### Managing Indexes at Runtime
 * **Example:** Create a tenant's vector index
 * ```typescript
 * // init — bind the operation to the collection
 * const createIndex = yield* AWS.OpenSearchServerless.CreateIndex(collection);
 *
 * // runtime
 * yield* createIndex({
 *   indexName: `tenant-${tenantId}`,
 *   indexSchema: {
 *     mappings: {
 *       properties: {
 *         embedding: { type: "knn_vector", dimension: 1536 },
 *       },
 *     },
 *   },
 * });
 * ```
