Bulk importing documents

This function implements the HTTP API for bulk imports.

ArangoCollection.importDocuments

ArangoCollection.importDocuments(Collection<?> values, DocumentImportOptions options) : DocumentImportEntity

ArangoCollection.importDocuments(String values, DocumentImportOptions options) : DocumentImportEntity

Bulk imports the given values into the collection.

Arguments

  • values: Collection<?> or String

    • Collection<?>: A list of Objects that will be stored as documents

    • String: JSON-encoded array of objects that will be stored as documents

  • options: DocumentImportOptions

    • fromPrefix: String

      An optional prefix for the values in _from attributes. If specified, the value is automatically prepended to each _from input value. This allows specifying just the keys for _from.

    • toPrefix: String

      An optional prefix for the values in _to attributes. If specified, the value is automatically prepended to each _to input value. This allows specifying just the keys for _to.

    • overwrite: Boolean

      If this parameter has a value of true, then all data in the collection will be removed prior to the import. Note that any existing index definitions will be preseved.

    • waitForSync: Boolean

      Wait until documents have been synced to disk before returning.

    • onDuplicate: OnDuplicate

      Controls what action is carried out in case of a unique key constraint violation. Possible values are:

      • error: this will not import the current document because of the unique key constraint violation. This is the default setting.

      • update: this will update an existing document in the database with the data specified in the request. Attributes of the existing document that are not present in the request will be preseved.

      • replace: this will replace an existing document in the database with the data specified in the request.

      • ignore: this will not update an existing document and simply ignore the error caused by the unique key constraint violation. Note that update, replace and ignore will only work when the import document in the request contains the _key attribute. update and replace may also fail because of secondary unique key constraint violations.

    • complete: Boolean

      If set to true, it will make the whole import fail if any error occurs. Otherwise the import will continue even if some documents cannot be imported.

    • details: Boolean

      If set to true, the result will include an attribute details with details about documents that could not be imported.

Examples

ArangoDB arango = new ArangoDB.Builder().build();
ArangoDatabase db = arango.db("myDB");
ArangoCollection collection = db.collection("some-collection");

BaseDocument doc1 = new BaseDocument();
BaseDocument doc2 = new BaseDocument();
BaseDocument doc3 = new BaseDocument();
collection.importDocuments(Arrays.asList(doc1, doc2, doc3), new DocumentImportOptions());
