Purpose

  • Postgres sync fails when the source table has a JSONB column: UnsupportedOperationException: Doesn't support 'jsonb'.
  • Debezium already emits jsonb values as plain json strings (io.debezium.data.Json), same as the supported json type.
  • Map the jsonb type to string to support the same.

Tests

  • UT
