Supported Runtimes

Spark 3.5.x (Spark 4 hopefully coming soon) based runtimes on jdk 17 (OSS 2.13 builds are also provided).

Databricks requires the use of JNAME, with its associated reduction in support, in order to run on a non-jdk 8 VM for DBRs 14.0, 14.3 and 15.4. 16.x moves to JDK 17 by default.

Supported DMNContextProviders

The following types are supported and provided to the org.kie.dmn.api.core.DMNContext

  • JSON - string json representation
  • StringType
  • IntegerType
  • LongType
  • BooleanType
  • DoubleType
  • FloatType
  • BinaryType - provided as a byte[]
  • ByteType
  • ShortType
  • DateType - provided as a LocalDate
  • TimestampType - provided as a LocalDateTime

All other DDL types (decimal, struct, array etc.) are currently unsupported.

Non DDL Unary DMNContextProviders may be provided via a fully qualified class name and must provide a two arg constructor of DMNContextPath, Expression.

Supported DMNResultProviders

  • JSON - Serializes the org.kie.dmn.api.core.DMNResult.getDecisionResults
