  • oracle.pg.rdbms.OraclePgqlResultElement.java
  • oracle.pg.rdbms.OraclePgqlResultElementImpl.java
  • oracle.pg.rdbms.OraclePgqlResultImpl.java
  • oracle.pg.rdbms.OraclePgqlResultIterable.java

• The following Java API methods, objects and fields in oracle.pgx.api are no longer supported:

  Desupported Methods:

  • PgxCollection methods:
    • addAllAsync(Collection<E> source)
    • removeAllAsync(Collection<E> source)
    • addAll(ID...ids)
    • removeAll(ID...ids)
  • PgqlResultSet methods:
    • getResults(): instead, use PgqlResultSet to directly iterate the result set
    • destroy()
  • User-defined pattern matching semantic methods:
    • PgxGraph#queryPgql(String, PatternMatchingSemantic): instead, use PgxGraph#queryPgql(String)
    • PgxSession.setPatternMatchingSemantic(..)
  • GraphMetaData constructors and related methods:
    • GraphMetaData()
    • GraphMetaData(GraphMetaData other, java.net.URI baseUri)
    • GraphMetaData(IdType vertexIdType)
    • GraphMetaData.setVertexIdType()
    • GraphMetaData.setEdgeIdType()
  • PgxSession#getAvailableSnapshots(GraphConfig): instead, use PgxSession#getAvailableSnapshots(PgxGraph)
  • All Analyst#filteredBfs and Analyst#filteredDfs methods that accepts filter parameter: instead, use the navigator parameter

  Desupported Objects

  • PgqlResult(a result of resultSet.getResults().iterator().next(): instead, use PgxResult as returned from resultSet.iterator().next()

  Desupported Fields

  • pattern_matching_semantic configuration field
• The Java API method AbstractGraphConfigBuilder#setNodeIdType in oracle.pgx.config is desupported. Instead, use AbstractGraphConfigBuilder#setVertexIdType().
• The following PyPGX classes are desupported in pypgx package. Instead, use pypgx.api.filters subpackage to access these classes:
  • EdgeFilter
  • GraphFilter
  • VertexFilter

• The following PyPGX classes are desupported in pypgx.api package. Instead, use pypgx.api.frames subpackage to access these classes:

  • PgxCsvFrameReader
  • PgxCsvFrameStorer
  • PgxDbFrameReader
  • PgxDbFrameStorer
  • PgxFrame
  • PgxFrameBuilder
  • PgxFrameColumn
  • PgxGenericFrameReader
  • PgxGenericFrameStorer
  • PgxPgbFrameReader
  • PgxPgbFrameStorer
• The following Python API packages are no longer supported:
  • common: This internal package is desupported. Few of the classes from this package are moved to the public package pypgx.api.
  • utils: This internal package is renamed to _utils.
• Graph property text search based on Apache Solr/Lucene is desupported. Instead, use PGQL query expressions.
• The PGX property type DATE is desupported. Instead, use LOCAL_DATE or TIMESTAMP.
• Property Graph support for data stored in Oracle NoSQL Database is desupported.
• Support for Gremlin Groovy shell is desupported.
• Apache Tinkerpop API support for Oracle Database is desupported.
• Loading data from flat file formats into the property graph schema is desupported.
• Support for the Apache Groovy-based shell was deprecated in 19c and is now desupported.
• Support for Apache HBase and Apache HDFS on Cloudera CDH5 is desupported.
