syncguard/firestore/operations/acquire.d.ts

Functional TypeScript library for distributed locking across microservices. Prevents race conditions with Redis, PostgreSQL, Firestore, and custom backends. Features automatic lock management, timeout handling, and extensible architecture.

import type { CollectionReference, Firestore } from "@google-cloud/firestore";
import { type AcquireResult, type KeyOp } from "../../common/backend.js";
import type { FirestoreCapabilities, FirestoreConfig } from "../types.js";
/**
 * Creates Firestore acquire operation with transactional fencing.
 * @see ../types.ts for document schemas
 */
export declare function createAcquireOperation(db: Firestore, locksCollection: CollectionReference, fenceCounterCollection: CollectionReference, config: FirestoreConfig): (opts: KeyOp & {
    ttlMs: number;
}) => Promise<AcquireResult<FirestoreCapabilities>>;
