Sample requests

GET /openapi/ha3/instances/{instanceId}/tables/{tableName}

Response parameters

Parameter	Type	Description	Example
	object
requestId	string	requestId	2AE63638-5420-56DC-BF59-37D8174039A0
result	object	The results returned.
status	string	The state of the index table. Valid values: NEW, PUBLISH, IN_USE, NOT_USE, STOP_USE, RESTORE_USE, and FAIL. After an index is created in an OpenSearch Retrieval Engine Edition instance, the index enters the IN_USE state. If the first full index fails to be created in an OpenSearch Vector Search Edition instance of the new version, the index is in the FAIL state.	IN_USE
dataSource	object
config	object
accessKey	string	AK	ak
accessSecret	string	AS	as
fieldSchema	object	The field. The value is a key-value pair in which the key indicates the field name and value indicates the field type.
	string	id	{ "id": "INT64", "source_image": "STRING", "namespace": "INT64", "source_image_vector": "MULTI_FLOAT" }
vectorIndex	array<object>	The index schema.
	object
indexName	string	The name of the index schema.	test_odps
vectorField	string	The vector field.	source_image_vector
sparseIndexField	string	The field that stores the indexes of the elements in sparse vectors.	sparse_indices
sparseValueField	string	The field that stores the elements in sparse vectors.	sparse_values
dimension	string	The dimension of the vector.	128
vectorIndexType	string	The vector retrieval algorithm.	Qc
distanceType	string	The distance type.	SquaredEuclidean
namespace	string	The namespace field.	namespace
advanceParams	object	The configurations of the index schema.
buildIndexParams	string	The index building parameters.	{}
searchIndexParams	string	The index retrieval parameters.	{}
minScanDocCnt	string	The minimum number of retrieved candidate sets.	20000
linearBuildThreshold	string	The threshold for linear building.	5000
dataProcessConfig	array<object>	The configurations about field processing.
	object
operator	string	The method used to process the field. Valid values: copy and vectorize. A value of copy indicates that the value of the source field is copied to the destination field. A value of vectorize indicates that the value of the source field is vectorized by a vectorization model and the output vector is stored in the destination field.	vectorize
dstField	string	The destination field.	source_image_vector
srcField	string	The source field.	source_image
params	object	The information about the model.
vectorModel	string	The vectorization model.	clip
vectorModal	string	The data type.	image
srcFieldConfig	object	The source of the data to be vectorized.
ossEndpoint	string	The Object Storage Service (OSS) endpoint.	oss-cn-hangzhou-internal.aliyuncs.com
ossBucket	string	OSS Bucket	test
uid	string	The ID of the Alibaba Cloud account.	uid
