Qdrant

Since Camel 4.5

Only producer is supported

The Qdrant Component provides support for interacting with the Qdrant Vector Database.

URI format

qdrant:collection[?options]

Where collection represents a named set of points (vectors with a payload) defined in your database.

Configuring Options

Camel components are configured on two separate levels:

  • component level

  • endpoint level

Configuring Component Options

At the component level, you set general and shared configurations that are, then, inherited by the endpoints. It is the highest configuration level.

For example, a component may have security settings, credentials for authentication, urls for network connection and so forth.

Some components only have a few options, and others may have many. Because components typically have pre-configured defaults that are commonly used, then you may often only need to configure a few options on a component; or none at all.

You can configure components using:

  • the Component DSL.

  • in a configuration file (application.properties, *.yaml files, etc).

  • directly in the Java code.

Configuring Endpoint Options

You usually spend more time setting up endpoints because they have many options. These options help you customize what you want the endpoint to do. The options are also categorized into whether the endpoint is used as a consumer (from), as a producer (to), or both.

Configuring endpoints is most often done directly in the endpoint URI as path and query parameters. You can also use the Endpoint DSL and DataFormat DSL as a type safe way of configuring endpoints and data formats in Java.

A good practice when configuring options is to use Property Placeholders.

Property placeholders provide a few benefits:

  • They help prevent using hardcoded urls, port numbers, sensitive information, and other settings.

  • They allow externalizing the configuration from the code.

  • They help the code to become more flexible and reusable.

The following two sections list all the options, firstly for the component followed by the endpoint.

Component Options

The Qdrant component supports 8 options, which are listed below.

Name Description Default Type

apiKey (producer)

Sets the API key to use for authentication.

String

configuration (producer)

The configuration;.

QdrantConfiguration

host (producer)

The host to connect to.

localhost

String

lazyStartProducer (producer)

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

port (producer)

The port to connect to.

6334

int

timeout (producer)

Sets a default timeout for all requests.

Duration

tls (producer)

Whether the client uses Transport Layer Security (TLS) to secure communications.

false

boolean

autowiredEnabled (advanced)

Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.

true

boolean

Endpoint Options

The Qdrant endpoint is configured using URI syntax:

qdrant:collection

With the following path and query parameters:

Path Parameters (1 parameters)

Name Description Default Type

collection (producer)

Required The collection Name.

String

Query Parameters (6 parameters)

Name Description Default Type

apiKey (producer)

Sets the API key to use for authentication.

String

host (producer)

The host to connect to.

localhost

String

port (producer)

The port to connect to.

6334

int

timeout (producer)

Sets a default timeout for all requests.

Duration

tls (producer)

Whether the client uses Transport Layer Security (TLS) to secure communications.

false

boolean

lazyStartProducer (producer (advanced))

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

Collection Samples

In the route below, we use the qdrant component to create a collection named myCollection with the given parameters:

  • Java

from("direct:in")
    .setHeader(Qdrant.Headers.ACTION)
        .constant(QdrantAction.CREATE_COLLECTION)
    .setBody()
        .constant(
            Collections.VectorParams.newBuilder()
                .setSize(2)
                .setDistance(Collections.Distance.Cosine).build())
    .to("qdrant:myCollection");

Points Samples

Upsert

In the route below we use the qdrant component to perform insert + updates (upsert) on points in the collection named myCollection:

  • Java

from("direct:in")
    .setHeader(Qdrant.Headers.ACTION)
        .constant(QdrantAction.UPSERT)
    .setBody()
        .constant(
            Points.PointStruct.newBuilder()
                .setId(id(8))
                .setVectors(VectorsFactory.vectors(List.of(3.5f, 4.5f)))
                .putAllPayload(Map.of(
                        "foo", value("hello"),
                        "bar", value(1)))
                .build())
    .to("qdrant:myCollection");

Retrieve

In the route below, we use the qdrant component to retrieve information of a single point by id from the collection named myCollection:

  • Java

from("direct:in")
    .setHeader(Qdrant.Headers.ACTION)
        .constant(QdrantAction.RETRIEVE)
    .setBody()
        .constant(PointIdFactory.id(8))
    .to("qdrant:myCollection");

Delete

In the route below, we use the qdrant component to delete points from the collection named myCollection according to a criteria:

  • Java

from("direct:in")
    .setHeader(Qdrant.Headers.ACTION)
        .constant(QdrantAction.DELETE)
    .setBody()
        .constant(ConditionFactory.matchKeyword("foo", "hello"))
    .to("qdrant:myCollection");

INFO

In the route below, we use the qdrant component to get information about the collection named myCollection:

Java
from("direct:in")
    .setHeader(Qdrant.Headers.ACTION)
        .constant(QdrantAction.COLLECTION_INFO)
    .to("qdrant:myCollection")
    .process(this::process);

If there is a collection, you will receive a reply of type Collections.CollectionInfo. If there is not, the exchange will contain an exception of type QdrantActionException with a cause of type StatusRuntimeException statusRuntimeException and status Status.NOT_FOUND.

Spring Boot Auto-Configuration

When using qdrant with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-qdrant-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
