Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

[1.0.5] - 2024-10-15

  • Fix a bug where starting in clickhouse 24.7, users would get default values for the given data type instead of real results. #32

[1.0.4] - 2024-10-05

  • Implement PrintSchemaAndCapabilities command. Enables the ddn CLI to perform introspection without needing to start an instance of the connector, which makes introspection faster. Note the DDN CLI does not yet implement this.
  • Bug fix: scalar aggregates may return other scalars, creating dependencies. Fix schema response not including those scalar type dependencies

[1.0.3]

  • Update SDK version to enable unauthorized access to health endpoint

[1.0.2]

  • Allow DateTime64 shorthand for DateTime64(3)
  • Allow Decimal shorthand for Decimal(10, 0)
  • Make datatypes case insensitive
  • When introspection returns no columns (parameterized view issue), preserve any manually written columns
  • Correct support for casting from JSON Objects paramters to named Tuples, and JSON Arrays to anonymous tuples
  • Fix printing tuples in bound parameters

[1.0.1]

  • Bug fix: remove erroneous group by and order by clauses in foreach queries. Remote relationships should now function as expected. The previous fix was incorrect.

[1.0.0]

  • Stable Release

[0.2.11]

  • Bugfix: add missing group by clause for foreach queries. This should fix remote relationships.

[0.2.10]

  • Correct CLI implementation of Init command (used to behave the same as update)
  • Update sdk & errors
  • Fix version returned by capabilities
  • Fix parameter escaping, enabling complex data types as parameters
  • Remove deprecated JSON data type, see clickhouse docs

[0.2.9]

  • Change namespaceing to use . separator instead of _. We assume table names are less likely to contain periods, so this reduces likelyhood of naming conflicts.This will change generated type names and will thus manifest as a breaking change for some users
  • Support Nested column types correctly, (previously these were treated as essentially Tuple columns)
  • Support subfield selection on complex column types.
  • Add support for relationships on column subfields, if the path to the subfield does not include lists
  • Fix datatype parser: add ability to parse SimpleAggregateFunction and AggregateFunction columns

[0.2.8]

  • Make spans visible to cloud console users (tag spans with internal.visibility = 'user')

[0.2.7]

  • Fix a bug introduced in 0.2.6 that would cause responses including a single quote to be serialized as invalid JSON strings

[0.2.6]

  • Add additional trace spans for SQL generation and query execution
  • Do not parse db response as JSON, instead send it back directly

[0.2.5]

  • Implement validate cli command
  • Do not write out config file unless it has changed. This avoids issues with the ddn cli which watches for filechange events
  • Cast variables to UUID before comparison to UUID columns. This enables remote relationships to UUID columns

[0.2.4]

  • Allow explain of invalid foreach queries. Will generate invalid SQL, for proper execution these should be parameterized

[0.2.3]

  • Fix ordering of result sets for foreach queries (remote joins)

[0.2.2]

  • Return error if empty list of query variables passed. Variables should be ommited or be a list with at least one member
  • Use table comment as description for corresponding collection and object type
  • Return json representation for applicable scalar types in schema response
  • Add configuration.schema.json to generated configuration directory
  • Bump ndc-spec dependency to 0.1.1
  • Config breaking change: use maps for tables and columns list, rather than arrays. This should help avoid duplicate alias issues
  • Move parsing column data types into configuration time and startup time, instead of query execution time. This should give error feedback earlier
  • Allow tables and native query return types to be marked as identical to return types for other tables/queries
  • Support parameterized views (don't support column valued arguments)
  • Support parameterized native queries, except in foreach queries. Also don't support column valued arguments
  • Change explain output so the console knows how to extract generated SQL and sql explain plan to display to the user
  • Pretty print explain SQL output
  • Fix a bug where no result sets where returned when foreach predicate didn't match any rows. Correct behavior: empty result set is returned

[0.2.1]

CLI

  • ignore casing for log-level flag

Server

  • default to serve command
  • default HASURA_CONFIGURATION_DIRECTORY to /etc/connector

CI

  • correct connnector-definition.tgz archive: make root of archive relative (was absolute)

[0.2.0]

  • DDN Beta release
  • add cli plugin
  • remove configuration server mode

[0.1.1]

  • DDN Alpha Release
