Project: Qdrant (App Definition and Development / Database)
File: QUICK_START_GRPC.md

DISCLAIMER: The GRPC API for Qdrant are under development and disabled by default in production builds. Limited functionality is exposed at the moment. This draft tutorial is for testing and internal use only. This tutorial would use the grpcurl command line tool in order to perform grpc requests. Please follow the steps provided in the in order to install it. The GRPC feature is disabled by default in order not to impact the production binary until complete. In order to run qdrant with grpc feature enabled, executed the following command: ```bash QDRANTSERVICEGRPC_PORT="6334" cargo run --bin qdrant ``` It will run qdrant exposing both json and grpc API. If you do not want to use JSON API, add ``--no-default-features `` flag as well: ```bash QDRANTSERVICEGRPC_PORT="6334" cargo run --no-default-features --bin qdrant ``` Note that actix is not compiled in this case. Execute the following command ```bash grpcurl -plaintext -import-path ./lib/api/src/grpc/proto/ -proto qdrant.proto -d '{}' 0.0.0.0:6334 qdrant.Qdrant/HealthCheck ``` Here and below the ```./lib/api/src/grpc/proto/``` should be a path to the folder with a protobuf schemas. Expected response: ```json { "title": "qdrant - vector search engine", "version": "<version>" } ``` First - let's create a collection with dot-production metric. ```bash grpcurl -plaintext -import-path ./lib/api/src/grpc/proto/ -proto qdrant.proto -d '{ "collectionname": "testcollection", "vectors_config": { "params": { "size": 4, "distance": "Dot" } } }' \ 0.0.0.0:6334 qdrant.Collections/Create ``` Expected response: ```json { "result": true, "time": 0.482865481 } ``` We can now view the list of collections to ensure that the collection was created: ```bash grpcurl -plaintext -import-path ./lib/api/src/grpc/proto/ -proto qdrant.proto 0.0.0.0:6334 qdrant.Collections/List ``` Expected response: ```json { "collections": [ { "name": "test_collection" } ], "time": 9.4219e-05 } ``` The collection could also be updated: ```bash grpcurl -plaintext -import-path ./lib/api/src/grpc/proto/ -proto qdrant.proto -d '{ "collectionname": "testcollection", "optimizers_config": { "maxsegmentsize": 100 } }' \ 0.0.0.0:6334 qdrant.Collections/Update ``` Let's now add vectors with some payload: ```bash grpcurl -plaintext -import-path ./lib/api/src/grpc/proto/ -proto qdrant.proto -d '{ "collectionname": "testcollection", "wait": true, "points": [ { "id": { "num": 1 }, "vectors": { "vector": { "data": [0.05, 0.61, 0.76, 0.74] } }, "payload": { "city": { "string_value": "Berlin" }, "country": { "string_value": "Germany" }, "population": { "integer_value": 1000000 }, "square": { "double_value": 12.5 }, "coords": { "struct_value": { "fields":{ "lat": { "double_value": 1.0 }, "lon": { "double_value": 2.0 } } } } } }, {"id": {"num": 2}, "vectors": {"vector": {"data": [0.18, 0.01, 0.85, 0.80]}}, "payload": {"square": {"listvalue": {"values": [{"integervalue": 10}, {"integer_value": 11}]}} }}, {"id": {"num": 3}, "vectors": {"vector": {"data": [0.24, 0.18, 0.22, 0.45]}}, "payload": {"count": {"listvalue": {"values": [{"integervalue": 0}]}} }}, {"id": {"num": 4}, "vectors": {"vector": {"data": [0.24, 0.18, 0.22, 0.45]}}, "payload": {"coords": {"listvalue": {"values": [{ "structvalue": {"fields": { "lat": { "doublevalue":1.0 }, "lon": { "doublevalue": 2.0 } } } }, { "structvalue": {"fields": { "lat": { "doublevalue":3.0 }, "lon": { "double_value": 4.0 } } } }] }} }}, {"id": {"num": 5}, "vectors": {"vector": {"data": [0.35, 0.08, 0.11, 0.44]}}} ] }' \ 0.0.0.0:6334 qdrant.Points/Upsert ``` Expected response: ```json { "result": { "status": "Completed" }, "time": 0.004128988 } ``` The qdrant.Collections/UpdateCollections rpc could also be used to delete a collection: ```bash grpcurl -plaintext -import-path ./lib/api/src/grpc/proto/ -proto qdrant.proto -d '{ "collectionname": "testcollection" }' \ 0.0.0.0:6334 qdrant.Collections/Delete ```
