Use tools and libraries to query data stored in an {{% product-name %}} bucket.

InfluxDB v3 supports the following APIs and languages for querying data:

• Flight+RPC with SQL or InfluxQL. Use InfluxDB client libraries and Flight+RPC clients to query with SQL or InfluxQL and retrieve data in Arrow in-memory format.
• Flight SQL with SQL or InfluxQL. Use Flight SQL clients to query with SQL or InfluxQL and retrieve data in Arrow in-memory format.
• HTTP /query endpoint for InfluxDB v1 compatibility when you bring workloads and code from v1.x to v3. Use the /query endpoint with InfluxQL and tools such as Telegraf, HTTP clients, and InfluxDB v1 client libraries to query and retrieve data in JSON or CSV format.

/api/v2/query endpoint can't query InfluxDB v3

{{% product-name %}} doesn't support the InfluxDB v2 HTTP /api/v2/query endpoint and isn't optimized for the Flux query language. Use SQL or InfluxQL to query data stored in InfluxDB v3. {{% /warn %}}
