Qdrant-Spark Connector

Apache Spark is a distributed computing framework designed for big data processing and analytics. This connector enables Qdrant to be a storage destination in Spark.

Installation

Important

Requires Java 8 or above.

GitHub Releases

The packaged jar file can be found here.

Building from source

To build the jar from source, you need JDK@8 and Maven installed. Once the requirements have been satisfied, run the following command in the project root.

mvn package

This will build and store the fat JAR in the target directory by default.

Maven Central

For use with Java and Scala projects, the package can be found here.

Usage

Creating a Spark session (Single-node) with Qdrant support

from pyspark.sql import SparkSession

spark = SparkSession.builder.config(
        "spark.jars",
        "spark-VERSION.jar",  # Specify the downloaded JAR file
    )
    .master("local[*]")
    .appName("qdrant")
    .getOrCreate()

Loading data

Important

Before loading the data using this connector, a collection has to be created in advance with the appropriate vector dimensions and configurations.

The connector supports ingesting multiple named/unnamed, dense/sparse vectors.

Click each to expand.

Unnamed/Default vector

  <pyspark.sql.DataFrame>
   .write
   .format("io.qdrant.spark.Qdrant")
   .option("qdrant_url", <QDRANT_GRPC_URL>)
   .option("collection_name", <QDRANT_COLLECTION_NAME>)
   .option("embedding_field", <EMBEDDING_FIELD_NAME>)  # Expected to be a field of type ArrayType(FloatType)
   .option("schema", <pyspark.sql.DataFrame>.schema.json())
   .mode("append")
   .save()

Named vector

  <pyspark.sql.DataFrame>
   .write
   .format("io.qdrant.spark.Qdrant")
   .option("qdrant_url", <QDRANT_GRPC_URL>)
   .option("collection_name", <QDRANT_COLLECTION_NAME>)
   .option("embedding_field", <EMBEDDING_FIELD_NAME>)  # Expected to be a field of type ArrayType(FloatType)
   .option("vector_name", <VECTOR_NAME>)
   .option("schema", <pyspark.sql.DataFrame>.schema.json())
   .mode("append")
   .save()

NOTE

The embedding_field and vector_name options are maintained for backward compatibility. It is recommended to use vector_fields and vector_names for named vectors as shown below.

Multiple named vectors

  <pyspark.sql.DataFrame>
   .write
   .format("io.qdrant.spark.Qdrant")
   .option("qdrant_url", "<QDRANT_GRPC_URL>")
   .option("collection_name", "<QDRANT_COLLECTION_NAME>")
   .option("vector_fields", "<COLUMN_NAME>,<ANOTHER_COLUMN_NAME>")
   .option("vector_names", "<VECTOR_NAME>,<ANOTHER_VECTOR_NAME>")
   .option("schema", <pyspark.sql.DataFrame>.schema.json())
   .mode("append")
   .save()

Sparse vectors

  <pyspark.sql.DataFrame>
   .write
   .format("io.qdrant.spark.Qdrant")
   .option("qdrant_url", "<QDRANT_GRPC_URL>")
   .option("collection_name", "<QDRANT_COLLECTION_NAME>")
   .option("sparse_vector_value_fields", "<COLUMN_NAME>")
   .option("sparse_vector_index_fields", "<COLUMN_NAME>")
   .option("sparse_vector_names", "<SPARSE_VECTOR_NAME>")
   .option("schema", <pyspark.sql.DataFrame>.schema.json())
   .mode("append")
   .save()

Multiple sparse vectors

  <pyspark.sql.DataFrame>
   .write
   .format("io.qdrant.spark.Qdrant")
   .option("qdrant_url", "<QDRANT_GRPC_URL>")
   .option("collection_name", "<QDRANT_COLLECTION_NAME>")
   .option("sparse_vector_value_fields", "<COLUMN_NAME>,<ANOTHER_COLUMN_NAME>")
   .option("sparse_vector_index_fields", "<COLUMN_NAME>,<ANOTHER_COLUMN_NAME>")
   .option("sparse_vector_names", "<SPARSE_VECTOR_NAME>,<ANOTHER_SPARSE_VECTOR_NAME>")
   .option("schema", <pyspark.sql.DataFrame>.schema.json())
   .mode("append")
   .save()

Combination of named dense and sparse vectors

  <pyspark.sql.DataFrame>
   .write
   .format("io.qdrant.spark.Qdrant")
   .option("qdrant_url", "<QDRANT_GRPC_URL>")
   .option("collection_name", "<QDRANT_COLLECTION_NAME>")
   .option("vector_fields", "<COLUMN_NAME>,<ANOTHER_COLUMN_NAME>")
   .option("vector_names", "<VECTOR_NAME>,<ANOTHER_VECTOR_NAME>")
   .option("sparse_vector_value_fields", "<COLUMN_NAME>,<ANOTHER_COLUMN_NAME>")
   .option("sparse_vector_index_fields", "<COLUMN_NAME>,<ANOTHER_COLUMN_NAME>")
   .option("sparse_vector_names", "<SPARSE_VECTOR_NAME>,<ANOTHER_SPARSE_VECTOR_NAME>")
   .option("schema", <pyspark.sql.DataFrame>.schema.json())
   .mode("append")
   .save()

No vectors - Entire dataframe is stored as payload

  <pyspark.sql.DataFrame>
   .write
   .format("io.qdrant.spark.Qdrant")
   .option("qdrant_url", "<QDRANT_GRPC_URL>")
   .option("collection_name", "<QDRANT_COLLECTION_NAME>")
   .option("schema", <pyspark.sql.DataFrame>.schema.json())
   .mode("append")
   .save()

Databricks

Tip

Check out our example of using the Spark connector with Databricks.

You can use the connector as a library in Databricks to ingest data into Qdrant.

Go to the Libraries section in your cluster dashboard.
Select Install New to open the library installation modal.
Search for io.qdrant:spark:VERSION in the Maven packages and click Install.

Datatype support

The appropriate Spark data types are mapped to the Qdrant payload based on the provided schema.
