0.8.5 (2021-08-23)

0.8.4 (2021-07-15)

0.7.6 (2020-01-17)

  • Fix unhashable type error for sortkey reflection in SQLAlchemy >= 1.3.11 (Issue #180)
  • Expose supported types for import from the dialect (Issue #181)
  • Reflect column comments (Issue #186)

0.7.5 (2019-10-09)

  • Extend psycopg2 package version check to also support psycopg2-binary and psycopg2cffi (Issue #178)

0.7.4 (2019-10-08)

  • Drop hard dependency on psycopg2 but require package to be present on runtime (Issue #165)
  • Switch from info to keyword arguments on columns for SQLAlchemy >= 1.3.0 (Issue #161)
  • Add support for column info on redshift late binding views (Issue #159)
  • Add support for MAXFILESIZE argument to UNLOAD. (Issue #123)
  • Add support for the CREATE LIBRARY command. (Issue #124)
  • Add support for the ALTER TABLE APPEND command. (Issue #162)
  • Add support for the CSV format to UnloadFromSelect. (Issue #169)
  • Update the list of reserved words (adds "az64" and "language") (Issue #176)

  • Avoid manipulating search path in table metadata fetch by using system tables directly (Issue #147)

0.7.1 (2018-01-17)

  • Fix incompatibility of reflection code with SQLAlchemy 1.2.0+ (Issue #138)

0.7.0 (2017-10-03)

  • Do not enumerate search_path with external schemas (Issue #120)
  • Return constraint name from get_pk_constraint and get_foreign_keys
  • Use Enums for Format, Compression and Encoding. Deprecate string parameters for these parameter types (Issue #133)
  • Update included certificate with the transitional ACM cert bundle (Issue #130)

0.6.0 (2017-05-04)

  • Support role-based access control in COPY and UNLOAD commands (Issue #88)
  • Increase max_identifier_length to 127 characters (Issue #96)
  • Fix a bug where table names containing a period caused an error on reflection (Issue #97)

0.5.0 (2016-04-21)

  • Support reflecting tables with foriegn keys to tables in non-public schemas (Issue #70)
  • Fix a bug where DISTKEY and SORTKEY could not be used on column names containing spaces or commas. This is a breaking behavioral change for a command like __table_args__ = {'redshift_sortkey': ('foo, bar')}. Previously, this would sort on the columns named foo and bar. Now, it sorts on the column named foo, bar. (Issue #74)

0.4.0 (2015-11-17)

  • Change the name of the package to sqlalchemy_redshift to match the naming convention for other dialects; the redshift_sqlalchemy package now emits a DeprecationWarning and references sqlalchemy_redshift. The redshift_sqlalchemy compatibility package will be removed in a future release. (Issue #58)
  • Fix a bug where reflected tables could have incorrect column order for some CREATE TABLE statements, particularly for columns with an IDENTITY constraint. (Issue #60)
  • Fix a bug where reflecting a table could raise a NoSuchTableError in cases where its schema is not on the current search_path (Issue #64)
  • Add python 3.5 to the list of versions for integration tests. (Issue #61)

0.3.1 (2015-10-08)

  • Fix breakages to CopyCommand introduced in 0.3.0: Thanks solackerman. (Issue #53)
    • When format is omitted, no FORMAT AS ... is appended to the query. This makes the default the same as a normal redshift query.
    • fix STATUPDATE as a COPY parameter

0.3.0 (2015-09-29)

  • Fix view support to be more in line with SQLAlchemy standards. get_view_definition output no longer includes a trailing semicolon and views no longer raise an exception when reflected as Table objects. (Issue #46)
  • Rename RedShiftDDLCompiler to RedshiftDDLCompiler. (Issue #43)
  • Update commands (Issue #52)
    • Expose optional TRUNCATECOLUMNS in CopyCommand.
    • Add all other COPY parameters to CopyCommand.
    • Move commands to their own module.
    • Support inserts into ordered columns in CopyCommand.

0.2.0 (2015-09-04)

  • Use SYSDATE instead of NOW(). Thanks bouk. (Issue #15)
  • Default to SSL with hardcoded AWS Redshift CA. (Issue #20)
  • Refactor of CopyCommand including support for specifying format and compression type. (Issue #21)
  • Explicitly require SQLAlchemy >= 0.9.2 for 'dialect_options'. (Issue #13)
  • Refactor of UnloadFromSelect including support for specifying all documented redshift options. (Issue #27)
  • Fix unicode issue with SORTKEY on python 2. (Issue #34)
  • Add support for Redshift DELETE statements that refer other tables in the WHERE clause. Thanks haleemur. (Issue #35)
  • Raise NoSuchTableError when trying to reflect a table that doesn't exist. (Issue #38)

0.1.2 (2015-08-11)

  • Register postgresql.visit_rename_table for redshift's alembic RenameTable. Thanks bouk. (Issue #7)

0.1.1 (2015-05-20)

  • Register RedshiftImpl as an alembic 3rd party dialect.

0.1.0 (2015-05-11)

  • First version of sqlalchemy-redshift that can be installed from PyPI
