| # Oracle | ||
| The Oracle Embedding Store integrates with | ||
| the [AI Vector Search Feature](https://docs.oracle.com/en/database/oracle/oracle-database/23/vecse/overview-ai-vector-search.html) of Oracle Database. | ||
|
|
||
| ## Maven Dependency | ||
|
|
||
| ```xml | ||
| <dependency> | ||
| <groupId>dev.langchain4j</groupId> | ||
| <artifactId>langchain4j-oracle</artifactId> | ||
| <version>0.34.0</version> | ||
|
|
||
| </dependency> | ||
| ``` | ||
|
|
||
| ## APIs | ||
|
|
||
| - `OracleEmbeddingStore` | ||
|
|
||
|
|
||
| ## Examples | ||
|
|
||
| - [OracleEmbeddingStoreExample](https://github.com/langchain4j/langchain4j-examples/blob/main/oracle-example/src/main/java/OracleEmbeddingStoreExample.java) | ||
|
|
||
| ## Usage | ||
|
|
||
| Instances of this store can be created by configuring a builder. The builder | ||
| requires that a DataSource and an embedding table be provided. The distance | ||
| between two vectors is calculated using [cosine similarity](https://docs.oracle.com/en/database/oracle/oracle-database/23/vecse/cosine-similarity.html) | ||
| which measures the cosine of the angle between two vectors. | ||
|
|
||
| It is recommended to configure a DataSource which pools connections, such as the | ||
| Universal Connection Pool or Hikari. A connection pool will avoid the latency of | ||
| repeatedly creating new database connections. | ||
|
|
||
| If an embedding table already exists in your database provide the table name. | ||
|
|
||
| ```java | ||
| EmbeddingStore embeddingStore = OracleEmbeddingStore.builder() | ||
| .dataSource(myDataSource) | ||
| .embeddingTable("my_embedding_table") | ||
| .build(); | ||
| ``` | ||
|
|
||
| If the table does not already exist, it can be created by passing a CreateOption | ||
| to the builder. | ||
|
|
||
| ```java | ||
| EmbeddingStore embeddingStore = OracleEmbeddingStore.builder() | ||
| .dataSource(myDataSource) | ||
| .embeddingTable("my_embedding_table", CreateOption.CREATE_IF_NOT_EXISTS) | ||
| .build(); | ||
| ``` | ||
|
|
||
| By default the embedding table will have the following columns: | ||
|
|
||
| | Name | Type | Description | | ||
| | ---- | ---- | ----------- | | ||
| | id | VARCHAR(36) | Primary key. Used to store UUID strings which are generated when the embedding store | | ||
| | embedding | VECTOR(*, FLOAT32) | Stores the embedding | | ||
| | text | CLOB | Stores the text segment | | ||
| | metadata | JSON | Stores the metadata | | ||
|
|
||
| If the columns of your existing table do not match the predefined column names | ||
| or you would like to use different column names, you can use a EmbeddingTable | ||
| builder to configure your embedding table. | ||
|
|
||
| ```java | ||
| OracleEmbeddingStore embeddingStore = | ||
| OracleEmbeddingStore.builder() | ||
| .dataSource(myDataSource) | ||
| .embeddingTable(EmbeddingTable.builder() | ||
| .createOption(CREATE_OR_REPLACE) // use NONE if the table already exists | ||
| .name("my_embedding_table") | ||
| .idColumn("id_column_name") | ||
| .embeddingColumn("embedding_column_name") | ||
| .textColumn("text_column_name") | ||
| .metadataColumn("metadata_column_name") | ||
| .build()) | ||
| .build(); | ||
| ``` | ||
|
|
||
| The builder provides two other methods that allow to create an index on the | ||
| embedding column and configure the use of exact or approximate search. | ||
|
