The solutions\noutlined in this section offer guidance on more advanced use cases.\n\nIntegrate with BigQuery\n\n**Summary:** Use Firebase Extensions to integrate data in Cloud Firestore\nwith BigQuery\n\n**Use case:** If you need to analyze large amounts of data, you can use\nBigQuery.\n\n[See the solution for BigQuery extensions](/docs/firestore/solutions/bigquery)\n\nImplement an AI-driven chatbot\n\n**Summary:** Use Firebase Extensions to add an AI-driven chatbot to your\napp.\n\n**Use case:** You can use chatbots to improve customer service, market a new\nfeature or service, provide sales quotes, or any number of use cases. Get\nstarted by using these extensions.\n\n[See the solution for AI chatbot extensions](/docs/firestore/solutions/ai-chatbot)\n\nEnrich handling of text\n\n**Summary:** Use Firebase Extensions to mine and analyze text data.\n\n**Use case:** If you need to summarize text, detect toxic speech, translate\ntext, or transcribe audio, use these extensions.\n\n[See the solution for text handling extensions](/docs/firestore/solutions/enriched-text)\n\nEnrich value of media\n\n**Summary:** Use Firebase Extensions to mine and analyze media streams.\n\n**Use case:** If you need to classify images, convert speech to text, or perform\noptical character recognition (OCR), use these extensions.\n\n[See the solution for media processing extensions](/docs/firestore/solutions/enriched-media)\n\nFirestore Lite, the streamlined REST-only Firestore Web SDK\n\n**Summary:** Build smaller Web apps with faster load times when offline cache\nisn't important and you only need online access to your database.\n\n**Use case:** If your app doesn't need to manage offline users, import\n`@firebase\\firestore-lite`. Then, code features that make use of the Firestore\nbackend.\n\n[See the solution for Firestore Lite](/docs/firestore/solutions/firestore-lite)\n\nAggregation queries\n\n**Summary:** Build an aggregate of your data in Cloud Firestore using\ntransactions and Cloud Functions.\n\n**Use case:** To query your data across collections, build an aggregate, then\nrun the query. For example, in a recommendations app, you might want to\nretrieve all the information for a particular restaurant from different\ncollections.\n\n[See the solution for aggregation queries](/docs/firestore/solutions/aggregation)\n\nDistributed counters\n\n**Summary:** Distribute updates across \"counter\" subcollections to update a\ndocument more frequently than Cloud Firestore currently supports.\n\n**Use case:** Use this solution to add \"counters\" to your app (for example, to\nrepresent upvotes), and update the corresponding document at a high frequency.\nCloud Firestore supports 2 writes/second on each document.\n\n[See the solution for distributed counters](/docs/firestore/solutions/counters)\n\nFull-text search\n\n**Summary:** Search for text contained in your Cloud Firestore documents.\n\n**Use case:** Users might want to search your app content, including text\ncontained in individual fields across your documents and collections. Use this\nsolution to enable full-text search.\n\n[See the solution for full-text search](/docs/firestore/solutions/search)\n\nBuild presence\n\n**Summary:** Add a presence system that identifies whether or not a user is\nactively connected.\n\n**Use case:** Use this solution to identify users that are actively connected to\nyour app. For example, in a chat app, you might use a presence system to\npopulate a list of users that are online.\n\n[See the solution for building presence](/docs/firestore/solutions/presence)\n\nSecure data access for users and groups\n\n**Summary:** Write security rules to control access to individual documents\nbased on user roles.\n\n**Use case:** Use this solution to build collaborative apps while minimizing\nthe risk of improper data access.\n\n[See the solution for secure data access](/docs/firestore/solutions/role-based-access)\n\nSchedule data exports\n\n**Summary:** Use the App Engine Cron Service to schedule exports of\nyour data.\n\n**Use case:** Use this solution to run export operations on a schedule.\n\n[See the solution for scheduling exports](/docs/firestore/solutions/schedule-export)"]]
