Deprecated Features

Review the deprecated features in Oracle Graph Server and Client.

• Oracle JDK 8 Support

  Oracle Graph Server and Client Release 23.4 is the last release that is supported on Oracle JDK 8. All future releases will support JDK 11 or JDK 17.

• Oracle Graph HDFS Connector

  Oracle Graph HDFS connector is deprecated.

• PgxSession.getGraphs() function

  The PgxSession.getGraphs() method is deprecated. Instead, use getGraphs(Namespace namespace).

• PyPGX
  • The following function signatures are deprecated for PgxGraph:
    • get_or_create_edge_property(name, data_type=None, dim=0)

      Instead, use get_or_create_edge_property(type, /, name).

    • get_or_create_edge_vector_property(data_type, dim, name=None)

      Instead, use get_or_create_edge_vector_property(type, dimension, /, name).

    • get_or_create_vertex_property(name, data_type=None, dim=0)

      Instead, use get_or_create_vertex_property(type, /, name).

    • get_or_create_vertex_vector_property(data_type, dim, name=None)

      Instead, use get_or_create_vertex_vector_property(type, dimension, /, name).

    Note the following changes that apply for the new signatures:

    • name is no longer optional
    • type is the first argument followed by dimension, and name is the final argument
    • data_type and dim are deprecated
  • DeepWalkModel.validation_fraction, Pg2vecModel.validation_fraction, and the validation_fraction argument of Analyst.pg2vec_builder() are deprecated.

    The loss is computed on all samples.

  • The following attributes on Operation are now deprecated: graph_id, operation_type, cost_estimate, total_cost_estimate, cardinality_estimate, pattern_info, and children. Instead, use the corresponding getter methods, such as get_graph_id(), get_operation_type(), and so on.
  • The pgx_version attribute in ServerInstance class is deprecated. Instead, use get_version().
  • The attribute pg_view_name in PartitionedGraphConfig is deprecated. Instead, use source_name and source_type (set to pg_view).
  • set_standarize in GraphWiseModelConfig is deprecated. Instead, use set_standardize.
  • The return value of PgqlResultSet.get_vertex_labels may or may not be a list.
• PgxML
  • The methods setValidationFraction and getValidationFraction are deprecated for DeepWalk and Pg2vec, the loss is now computed on all samples.
  • GraphWiseModel.inferAndGetExplanation() is deprecated. Instead, use GraphWiseModel.gnnExplainer() to obtain a GnnExplainer object for the model and use GnnExplainer.inferAndExplain().
  • Pg2vecModelBuilder.setUseGraphletSize(java.lang.Boolean useGraphletSize) method in oracle.pgx.api.mllib API is deprecated. Instead, use the Pg2vecModelBuilder.setUseGraphletSize(boolean useGraphletSize) method.
  • SupervisedGraphWiseModelBuilder.setLossFunction(SupervisedGraphWiseModelConfig.LossFunction ...) is deprecated. Instead, use SupervisedGraphWiseModelBuilder.setLossFunction(LossFunction ...) function.
• GraphServer#getInstance API

  The following GraphServer#getInstance APIs are deprecated:

  • GraphServer.getInstance(ClientConfig clientConfig, String username, char[] password, int refreshTimeBeforeTokenExpiry)
  • GraphServer.getInstance(String baseUrl, String username, char[] password, int refreshTimeBeforeTokenExpiry)
  • GraphServer.getInstance(String baseUrl, String kerberosTicketPath, int refreshTimeBeforeTokenExpiry)

  Instead, configure the refresh_time_before_token_expiry_seconds parameter in the pgx.conf file.

• Methods deprecated for PgqlViewGraphExpander

  PgqlViewGraphExpander.schema(String) and PgqlViewGraphExpander.owner(String) are deprecated. Instead, use PgqlViewGraphExpander.fromPgView(String, String).

• Graph Server (PGX) Configuration Fields

  The graph server configuration fields, server_cert and server_private_key are deprecated. Instead, use server_keystore.

• Subgraph Loading

  Creating Subgraphs using filter expressions is deprecated. Instead, use Loading a Subgraph from a PGQL Property Graph.
