v0.18.0

For installation and running instructions, see Get started.

Main changes

Starting from this version, we’ll respect semantic versioning conventions by using the middle number (y , instead of z, in x.y.z) to indicate minor versions. That is why this is v0.18.0, not v0.1.18.

Administration and troubleshooting

  • Improves error messages by including the location of the statement in question. #8646
  • Initial values of immutable system parameters can be specified via the meta-node command line. The initial values provided in the configuration file will be ignored. #8366

SQL features

  • Adds initial support for user-defined functions. #8597 #8644 #8255 #7943
  • Adds support for JSONB data type. #8256 #8181
  • Adds support for NULLS { FIRST | LAST } in ORDER BY clauses. #8485
  • New commands:
    • ALTER SOURCE RENAME TO #8778
    • SET TIME ZONE #8572
    • ALTER RELATION RENAME #7745
    • ALTER TABLE ADD/DROP COLUMN for regular tables (without connector settings). #8394
  • New functions:
    • array_length : Returns the length of an array. #8636
    • String functions implemented with the help of chatGPT. #8767 #8839
      • chr(integer) -> varchar
      • starts_with(varchar, varchar) -> boolean
      • initcap(varchar) -> varchar
      • lpad(varchar, integer) -> varchar

    • Adds support for microsecond precision for intervals. #8501

    • Data records that has null time values will be ignored by time window functions. #8146
    • Improves the behaviors of the exp operator when the operand is too large or small. #8309
    • Supports process time temporal join, which enables the joining of an append-only stream (such as Kafka) with a temporal table (e.g. a materialized view backed by MySQL CDC). This feature ensures that any updates made to the temporal table will not affect previous results obtained from the temporal join. Supports FOR SYSTEM_TIME AS OF NOW() syntax to express process time temporal join. #8480

Connectors

  • Adds a new field basetime to the load generator connector for generating timestamp data. The load generator will take this field as now and generates data accordingly. #8619
  • Empty cells in CSV are now parsed as null. #8709
  • Adds the Iceberg connector. #8508
  • Adds support for the upsert type to the Kafka sink connector. #8168
