Enhancements
  • Support creating query clusters and attaching materialized views to query clusters in order to query them via HTTP API
  • Add IF EXISTS syntax to DROP statements, e.g. DROP TABLE IF EXISTS "my_table", to prevent the statement from failing if an entity does not exist. Applies to DROP CLUSTER, DROP CONNECTION, DROP TABLE, DROP JOB, and DROP MATERIALIZED VIEW.

Bug Fixes
  • Minor bug fixes

2023.07.27-01.59

Enhancements
Bug Fixes
  • Snowflake Jobs:
    • Fixed an issue with a custom insert/update expression causing the job to fail if the field is also mapped in the select statement
    • On auto-managed tables, Upsolver will not create an extra column if the following conversion happens:
      • Original column is Double and got a value of type Long
      • Original column is Timestamp and got a value of type Date
      • Original column is Varchar
      • Original column is Variant In all other cases, we will create an extra column with the new type as the column name suffix. For example: if a column col was of type Bigint and got a Double value, we will create a column COL_DOUBLE in the Snowflake table
    • Fixed a delay in Materialized View on Job List/Index page

2023.07.19-02.34

Bug Fixes
  • Fixed tree on fields containing dots, e.g. turning {"a\.b": 1} to {"a.b": 1}.
  • Snowflake jobs: changed the file format to copy from Avro to JSON. This fixed an issue when ingesting records with sub-fields that have special characters.

2023.07.13-02.20

Enhancements
  • Added VALUE_INDEX_IN_ROW() - this function receives an element of an array of records and returns the 1-based index of the element position (incrementing regardless of whether the array is nested). Null values are not counted.
  • Added VALUE_INDEX_IN_ARRAY() - this function receives an element of an array of records and returns the 1-based index of the element position (index resets to 1 for each sub-array). Null values are not counted.
  • Ingestion wizard - support added for creating a heartbeat table within the wizard.
Bug Fixes
  • Reduce the frequency of metadata queries to Snowflake in order to reduce the cost of COMPUTE SERVICES charged by Snowflake.
  • [BREAKING CHANGE] Fixed RECORD_TO_JSON on fields containing dots, e.g. turning {"a.b": 1} to {"a\.b": 1}.
