Configuration property fixed at build time - All other configuration properties are overridable at runtime

Configuration property

Type

Default

quarkus.langchain4j.chroma.devservices.enabled

If DevServices has been explicitly enabled or disabled. DevServices is generally enabled by default, unless there is an existing configuration present.

When DevServices is enabled Quarkus will attempt to automatically configure and start a database when running in Dev or Test mode and when Docker is running.

Environment variable: QUARKUS_LANGCHAIN4J_CHROMA_DEVSERVICES_ENABLED

boolean

true

quarkus.langchain4j.chroma.devservices.image-name

The container image name to use, for container based DevServices providers.

Environment variable: QUARKUS_LANGCHAIN4J_CHROMA_DEVSERVICES_IMAGE_NAME

string

ghcr.io/chroma-core/chroma:1.3.0

quarkus.langchain4j.chroma.devservices.port

Optional fixed port the dev service will listen to.

If not defined, the port will be chosen randomly.

Environment variable: QUARKUS_LANGCHAIN4J_CHROMA_DEVSERVICES_PORT

int

quarkus.langchain4j.chroma.devservices.shared

Indicates if the Chroma server managed by Quarkus Dev Services is shared. When shared, Quarkus looks for running containers using label-based service discovery. If a matching container is found, it is used, and so a second one is not started. Otherwise, Dev Services for Chroma starts a new container.

The discovery uses the quarkus-dev-service-chroma label. The value is configured using the service-name property.

Container sharing is only used in dev mode.

Environment variable: QUARKUS_LANGCHAIN4J_CHROMA_DEVSERVICES_SHARED

boolean

true

quarkus.langchain4j.chroma.devservices.service-name

The value of the quarkus-dev-service-chroma label attached to the started container. This property is used when shared is set to true. In this case, before starting a container, Dev Services for Chroma looks for a container with the quarkus-dev-service-chroma label set to the configured value. If found, it will use this container instead of starting a new one. Otherwise, it starts a new container with the quarkus-dev-service-chroma label set to the specified value.

This property is used when you need multiple shared Chroma servers.

Environment variable: QUARKUS_LANGCHAIN4J_CHROMA_DEVSERVICES_SERVICE_NAME

string

chroma

quarkus.langchain4j.chroma.devservices.container-env."container-env"

Environment variables that are passed to the container.

Environment variable: QUARKUS_LANGCHAIN4J_CHROMA_DEVSERVICES_CONTAINER_ENV__CONTAINER_ENV_

Map<String,String>

quarkus.langchain4j.chroma.url

URL where the Chroma database is listening for requests

Environment variable: QUARKUS_LANGCHAIN4J_CHROMA_URL

string

required

quarkus.langchain4j.chroma.collection-name

The collection name.

Environment variable: QUARKUS_LANGCHAIN4J_CHROMA_COLLECTION_NAME

string

default

quarkus.langchain4j.chroma.timeout

The timeout duration for the Chroma client. If not specified, 5 seconds will be used.

Environment variable: QUARKUS_LANGCHAIN4J_CHROMA_TIMEOUT

Duration 

quarkus.langchain4j.chroma.log-requests

Whether requests to Chroma should be logged

Environment variable: QUARKUS_LANGCHAIN4J_CHROMA_LOG_REQUESTS

boolean

false

quarkus.langchain4j.chroma.log-responses

Whether responses from Chroma should be logged

Environment variable: QUARKUS_LANGCHAIN4J_CHROMA_LOG_RESPONSES

boolean

false

quarkus.langchain4j.chroma.api-version

The Chroma API version to use. V1 is deprecated (Chroma 0.x) and its support will be removed in the future. Please use Chroma 1.x which uses the V2 API.

Environment variable: QUARKUS_LANGCHAIN4J_CHROMA_API_VERSION

v1, v2

v2
About the Duration format

To write duration values, use the standard java.time.Duration format. See the Duration#parse() Java API documentation for more information.

You can also use a simplified format, starting with a number:

  • If the value is only a number, it represents time in seconds.

  • If the value is a number followed by ms, it represents time in milliseconds.

In other cases, the simplified format is translated to the java.time.Duration format for parsing:

  • If the value is a number followed by h, m, or s, it is prefixed with PT.

  • If the value is a number followed by d, it is prefixed with P.
