⚠ BREAKING CHANGES
backends:
Columns with Ibis
date
types are now returned as object dtype containing
datetime.date
objects when executing with the pandas backend.
impala:
Direct HDFS integration is removed and support for ingesting pandas DataFrames directly is as well. The Impala backend still works with HDFS, but data in HDFS must be managed outside of ibis.
api:
replace
ibis.show_sql(expr)
calls with
print(ibis.to_sql(expr))
or if using Jupyter or IPython
ibis.to_sql(expr)
bigquery:
nullifzero
is removed; use
nullif(0)
instead
bigquery:
zeroifnull
is removed; use
fillna(0)
instead
bigquery:
list_databases
is removed; use
list_schemas
instead
bigquery:
the bigquery
current_database
method returns the
data_project
instead of the
dataset_id
. Use
current_schema
to retrieve
dataset_id
. To explicitly list tables in a given project and dataset, you can use
f"{con.current_database}.{con.current_schema}"

⚠ BREAKING CHANGES
api:
the
interpolation
argument was only supported in the dask and pandas backends; for interpolated quantiles use dask or pandas directly
ir:
Dask and Pandas only
; cumulative operations that relied on implicit ordering from prior operations such as calls to
table.order_by
may no longer work, pass
order_by=...
into the appropriate cumulative method to achieve the same behavior.
api:
UUID, MACADDR and INET are no longer subclasses of strings. Cast those values to
string
to enable use of the string APIs.
impala:
ImpalaTable.rename
is removed, use
Backend.rename_table
instead.
pyspark:
PySparkTable.rename
is removed, use
Backend.rename_table
instead.
clickhouse:
ClickhouseTable
is removed. This class only provided a single
insert
method. Use the Clickhouse backend’s
insert
method instead.
datatypes:
The minimum version of
sqlglot
is now 17.2.0, to support much faster and more robust backend type parsing.
ir:
ibis.expr.selectors module is removed, use ibis.selectors instead
api:
passing a tuple or a sequence of tuples to table.order_by() calls is not allowed anymore; use ibis.asc(key) or ibis.desc(key) instead
ir:
the
ibis.common.validators
module has been removed and all validation rules from
ibis.expr.rules
, either use typehints or patterns from
ibis.common.patterns

⚠ BREAKING CHANGES
imports:
Use of
ibis.udf
as a module is removed. Use
ibis.legacy.udf
instead.
The minimum supported Python version is now Python 3.9
api:
group_by().count()
no longer automatically names the count aggregation
count
. Use
relabel
to rename columns.
backends:
Backend.ast_schema
is removed. Use
expr.as_table().schema()
instead.
snowflake/postgres:
Postgres UDFs now use the new
@udf.scalar.python
API. This should be a low-effort replacement for the existing API.

ops.NullLiteral
is removed
datatypes:
dt.Interval
has no longer a default unit,
dt.interval
is removed
deps:
snowflake-connector-python
’s lower bound was increased to 3.0.2, the minimum version needed to avoid a high-severity vulnerability. Please upgrade
snowflake-connector-python
to at least version 3.0.2.
api:
Table.difference()
,
Table.intersection()
, and
Table.union()
now require at least one argument.
postgres:
Ibis no longer automatically defines
first
/
last
reductions on connection to the postgres backend. Use DDL shown in https://wiki.postgresql.org/wiki/First/last_(aggregate) or one of the
pgxn
implementations instead.
api:
ibis.examples.<example-name>.fetch
no longer forwards arbitrary keyword arguments to
read_csv
/
read_parquet
.
datatypes:
dt.Interval.value_type
attribute is removed
api:
Table.count()
is no longer automatically named
"count"
. Use
Table.count().name("count")
to achieve the previous behavior.
trino:
The trino backend now requires at least version 0.321 of the
trino
Python package.
backends:
removed
AlchemyTable
,
AlchemyDatabase
,
DaskTable
,
DaskDatabase
,
PandasTable
,
PandasDatabase
,
PySparkDatabaseTable
, use
ops.DatabaseTable
instead
dtypes:
temporal unit enums are now available under
ibis.common.temporal
instead of
ibis.common.enums
.
clickhouse:
external_tables
can no longer be passed in
ibis.clickhouse.connect
. Pass
external_tables
directly in
raw_sql
/
execute
/
to_pyarrow
/
to_pyarrow_batches()
.
datatypes:
dt.Set
is now an alias for
dt.Array
bigquery:
Before this change, ibis timestamp is mapping to Bigquery TIMESTAMP type and no timezone supports. However, it’s not correct, BigQuery TIMESTAMP type should have UTC timezone, while DATETIME type is the no timezone version. Hence, this change is breaking the ibis timestamp mapping to BigQuery: If ibis timestamp has the UTC timezone, will map to BigQuery TIMESTAMP type. If ibis timestamp has no timezone, will map to BigQuery DATETIME type.
impala:
Cursors are no longer returned from DDL operations to prevent resource leakage. Use
raw_sql
if you need specialized operations that return a cursor. Additionally, table-based DDL operations now return the table they’re operating on.
api:
Column.first()
/
Column.last()
are now reductions by default. Code running these expressions in isolation will no longer be windowed over the entire table. Code using this function in
select
-based APIs should function unchanged.
bigquery:
when using the bigquery backend, casting float to int will no longer round floats to the nearest integer
ops.Hash:
The
hash
method on table columns on longer accepts the
how
argument. The hashing functions available are highly backend-dependent and the intention of the hash operation is to provide a fast, consistent (on the same backend, only) integer value. If you have been passing in a value for
how
, you can remove it and you will get the same results as before, as there were no backends with multiple hash functions working.
duckdb:
Some CSV files may now have headers that did not have them previously. Set
header=False
to get the previous behavior.
deps:
New environments will have a different default setting for
compression
in the ClickHouse backend due to removal of optional dependencies. Ibis is still capable of using the optional dependencies but doesn’t include them by default. Install
clickhouse-cityhash
and
lz4
to preserve the previous behavior.
api:
Table.set_column()
is removed; use
Table.mutate(name=expr)
instead
api:
the
suffixes
argument in all join methods has been removed in favor of
lname
/
rname
args. The default renaming scheme for duplicate columns has also changed. To get the exact same behavior as before, pass in
lname="{name}_x", rname="{name}_y"
.
ir:
IntervalType.unit
is now an enum instead of a string
type-system:
Inferred types of Python objects may be slightly different. Ibis now use
pyarrow
to infer the column types of pandas DataFrame and other types.
backends:
path
argument of
Backend.connect()
is removed, use the
database
argument instead
api:
removed
Table.sort_by()
and
Table.groupby()
, use
.order_by()
and
.group_by()
respectively
datatypes:
DataType.scalar
and
column
class attributes are now strings.
backends:
Backend.load_data()
,
Backend.exists_database()
and
Backend.exists_table()
are removed
ir:
Value.summary()
and
NumericValue.summary()
are removed
schema:
Schema.merge()
is removed, use the union operator
schema1 | schema2
instead
api:
ibis.sequence()
is removed

⚠ BREAKING CHANGES
api:
Snowflake identifiers are now kept
as is
from the database. Many table names and column names may now be in SHOUTING CASE. Adjust code accordingly.
backend:
Backends now raise
ibis.common.exceptions.UnsupportedOperationError
in more places during compilation. You may need to catch this error type instead of the previous type, which differed between backends.
ux:
Table.info
now returns an expression
ux:
Passing a sequence of column names to
Table.drop
is removed. Replace
drop(cols)
with
drop(*cols)
.
The
spark
plugin alias is removed. Use
pyspark
instead
ir:
removed
ibis.expr.scope
and
ibis.expr.timecontext
modules, access them under
ibis.backends.base.df.<module>
some methods have been removed from the top-level

move
_get_schema_using_query
to base class (
296cd7d
)
sqlalchemy:
remove the need for deferred columns (
e4011aa
)

remove use of deprecated
isnot
(
4ec53a4
)

Deprecations
api:
deprecate
.to_projection
in favor of
.as_table
(
7706a86
)
api:
deprecate
get_column
/
s
in favor of
__getitem__
/
__getattr__
syntax (
e6372e2
)
ir:
schedule DatabaseTable.change_name for removal (
e4bae26
)
schema:
schedule
Schema.delete()
and
Schema.append()
for removal (
45ac9a9
)
functions, methods and classes marked as deprecated are removed now
ir:
replace
HLLCardinality
with
ApproxCountDistinct
and
CMSMedian
with
ApproxMedian
operations.
backends:
the datatype of returned execution results now more closely matches that of the ibis expression’s type. Downstream code may need to be adjusted.
ir:
the
JSONB
type is replaced by the
JSON
type.
dev-deps:
expression types have been removed from
ibis.expr.api
. Use
import ibis.expr.types as ir
to access these types.
common:
removed
@immutable_property
decorator, use
@attribute.default
instead
timestamps:
the
timezone
argument to
to_timestamp
is gone. This was only supported in the BigQuery backend. Append
%Z
to the format string and the desired time zone to the input column if necessary.
deps:
ibis now supports at minimum duckdb 0.3.3. Please upgrade your duckdb install as needed.
api:
previously
ibis.connect
would return a
Table
object when calling
connect
on a parquet/csv file. This now returns a backend containing a single table created from that file. When possible users may use
ibis.read
instead to read files into ibis tables.
api:
histogram()
’s
closed
argument no longer exists because it never had any effect. Remove it from your
histogram
method calls.
pandas/dask:
the pandas and Dask backends now interpret casting ints to/from timestamps as seconds since the unix epoch, matching other backends.
datafusion:
register_csv
and
register_parquet
are removed. Pass filename to
register
method instead.
ir:
ops.NodeList
and
ir.List
are removed. Use tuples to represent sequence of expressions instead.
api:
re_extract
now follows
re.match
behavior. In particular, the
0
th group is now the entire string if there’s a match, otherwise the groups are 1-based.
datatypes:
enums are now strings. Likely no action needed since no functionality existed.
ir:
Replace
t[t.x.topk(...)]
with
t.semi_join(t.x.topk(...), "x")
.
ir:
ir.Analytic.type()
and
ir.TopK.type()
methods are removed.
api:
the default limit for table/column expressions is now
None
(meaning no limit).
ir
: join changes: previously all column names that collided between
left
and
right
tables were renamed with an appended suffix. Now for the case of inner joins with only equality predicates, colliding columns that are known to be equal due to the join predicates aren’t renamed.
impala:
kerberos support is no longer installed by default for the
impala
backend. To add support you’ll need to install the
kerberos
package separately.
ir:
ops.DeferredSortKey
is removed. Use
ops.SortKey
directly instead.
ir:
ibis.common.grounds.Annotable
is mutable by default now
ir:
node.has_resolved_name()
is removed, use
isinstance(node, ops.Named)
instead;
node.resolve_name()
is removed use
node.name
instead
ir:
removed
ops.Node.flat_args()
, directly use
node.args
property instead
ir:
removed
ops.Node.inputs
property, use the multipledispatched
get_node_arguments()
function in the pandas backend
ir:
Node.blocks()
method has been removed.
ir:
HasSchema
mixin class is no longer available, directly subclass
ops.TableNode
and implement schema property instead
ir:
Removed
Node.output_type
property in favor of abstractmethod
Node.to_expr()
which now must be explicitly implemented
ir:
Expr(Op(Expr(Op(Expr(Op)))))
is now represented as
Expr(Op(Op(Op)))
, so code using ibis internals must be migrated
pandas:
Use timezone conversion functions to compute the original machine localized value
common:
use
ibis.common.validators.{Parameter, Signature}
instead
ir:
ibis.expr.lineage.lineage()
is now removed
ir:
removed
ir.DestructValue
,
ir.DestructScalar
and
ir.DestructColumn
, use
table.unpack()
instead
ir:
removed
Node.root_tables()
method, use
ibis.expr.analysis.find_immediate_parent_tables()
instead
impala:
use other methods for pinging the database

⚠ BREAKING CHANGES
ir:
The following are breaking changes due to simplifying expression internals
ibis.expr.datatypes.DataType.scalar_type
and
DataType.column_type
factory methods have been removed,
DataType.scalar
and
DataType.column
class fields can be used to directly construct a corresponding expression instance (though prefer to use
operation.to_expr()
)
ibis.expr.types.ValueExpr._name
and
ValueExpr._dtype
fields are not accessible anymore. While these were not supposed to used directly, now
ValueExpr.has_name()
,
ValueExpr.get_name()
and
ValueExpr.type()
methods are the only way to retrieve the expression’s name and datatype.
ibis.expr.operations.Node.output_type
is a property now not a method, decorate those methods with
@property
ibis.expr.operations.Value
subclasses must define
output_shape
and
output_dtype
properties from now on (note the datatype abbreviation
dtype
in the property name)
ibis.expr.rules.cast()
,
scalar_like()
and
array_like()
rules have been removed
api:
Replace
t["a"].distinct()
with
t[["a"]].distinct()
.
deps:
The sqlalchemy lower bound is now 1.4
ir:
Schema.names and Schema.types attributes now have tuple type rather than list
expr:
Columns that were added or used in an aggregation or mutation would be alphabetically sorted in compiled SQL outputs. This was a vestige from when Python dicts didn’t preserve insertion order. Now columns will appear in the order in which they were passed to
aggregate
or
mutate
api:
dt.float
is now
dt.float64
; use
dt.float32
for the previous behavior.
ir:
Relation-based
execute_node
dispatch rules must now accept tuples of expressions.
ir:
removed ibis.expr.lineage.{roots,find_nodes} functions
config:
Use
ibis.options.graphviz_repr = True
to enable
hdfs:
Use
fsspec
instead of HDFS from ibis
udf:
Vectorized UDF coercion functions are no longer a public API.
The minimum supported Python version is now Python 3.8
config:
register_option
is no longer supported, please submit option requests upstream
backends:
Read tables with pandas.read_hdf and use the pandas backend
The CSV backend is removed. Use Datafusion for CSV execution.
backends:
Use the datafusion backend to read parquet files
Expr() -> Expr.pipe()
coercion functions previously in expr/schema.py are now in udf/vectorized.py
api:
materialize
is removed. Joins with overlapping columns now have suffixes.
kudu:
use impala instead: https://kudu.apache.org/docs/kudu_impala_integration.html
Any code that was relying implicitly on string-y behavior from UUID datatypes will need to add an explicit cast first.

Support
Improvement of the backend API. The former
Client
subclasses have been replaced by a
Backend
class that must subclass
ibis.backends.base.BaseBackend
. The
BaseBackend
class contains abstract methods for the minimum subset of methods that backends must implement, and their signatures have been standardized across backends. The Ibis compiler has been refactored, and backends don’t need to implement all compiler classes anymore if the default works for them. Only a subclass of
ibis.backends.base.sql.compiler.Compiler
is now required. Backends now need to register themselves as entry points. (

0.8 (2016-05-19)
This release brings initial PostgreSQL backend support along with a number of critical bug fixes and usability improvements. As several correctness bugs with the SQL compiler were fixed, we recommend that all users upgrade from earlier versions of Ibis.
New Features
Initial PostgreSQL backend contributed by Phillip Cloud.
Add
groupby
as an alias for
group_by
to table expressions
Bug Fixes
Fix an expression error when filtering based on a new field
Fix Impala's SQL compilation of using
OR
with compound filters
Various fixes with the

function in grouped table expressions
Fix CTE (
WITH
) extraction inside
UNION ALL
expressions.

0.7 (2016-03-16)
This release brings initial Kudu-Impala integration and improved Impala and SQLite support, along with several critical bug fixes.
New Features
Apache Kudu (incubating) integration for Impala users. Will add some documentation here when possible.
Add
use_https
option to
ibis.hdfs_connect
for WebHDFS connections in secure (Kerberized) clusters without SSL enabled.
Correctly compile aggregate expressions involving multiple subqueries.
To explain this last point in more detail, suppose you had:
The last expression now generates the correct Impala or SQLite SQL:
SELECT t0.`tmp` - t1.`tmp` AS `tmp`
FROM (
SELECT avg(`value`) / sum(`value`) AS `tmp`
FROM tbl
WHERE `flag` = '1'
CROSS JOIN (
SELECT avg(`value`) / sum(`value`) AS `tmp`
FROM tbl
WHERE `flag` = '0'
Bug Fixes
CHAR(n) and VARCHAR(n) Impala types now correctly map to Ibis string expressions
Fix inappropriate projection-join-filter expression rewrites resulting in incorrect generated SQL.
ImpalaClient.create_table correctly passes STORED AS PARQUET for format='parquet'.
Fixed several issues with Ibis dependencies (impyla, thriftpy, sasl, thrift_sasl), especially for secure clusters. Upgrading will pull in these new dependencies.
Do not fail in ibis.impala.connect when trying to create the temporary Ibis database if no HDFS connection passed.
Fix join predicate evaluation bug when column names overlap with table attributes.
Fix handling of fully-materialized joins (aka select * joins) in SQLAlchemy / SQLite.

0.6 (2015-12-01)
This release brings expanded pandas and Impala integration, including support for managing partitioned tables in Impala. See the new Ibis for Impala Users guide for more on using Ibis with Impala.
The Ibis for SQL Programmers guide also was written since the 0.5 release.
This release also includes bug fixes affecting generated SQL correctness. All users should upgrade as soon as possible.
New Features
New integrated Impala functionality. See Ibis for Impala Users for more details on these things.
Improved Impala-pandas integration. Create tables or insert into existing tables from pandas DataFrame objects.
Partitioned table metadata management API. Add, drop, alter, and insert into table partitions.
Add is_partitioned property to ImpalaTable.
Added support for LOAD DATA DDL using the load_data function, also supporting partitioned tables.
Modify table metadata (location, format, SerDe properties etc.) using ImpalaTable.alter
Interrupting Impala expression execution with Control-C will attempt to cancel the running query with the server.
Set the compression codec (e.g. snappy) used with ImpalaClient.set_compression_codec.
Get and set query options for a client session with ImpalaClient.get_options and ImpalaClient.set_options.
Add ImpalaTable.metadata method that parses the output of the DESCRIBE FORMATTED DDL to simplify table metadata inspection.
Add ImpalaTable.stats and ImpalaTable.column_stats to see computed table and partition statistics.
Add CHAR and VARCHAR handling
Add refresh, invalidate_metadata DDL options and add incremental option to compute_stats for COMPUTE INCREMENTAL STATS.
Add substitute method for performing multiple value substitutions in an array or scalar expression.
Division is by default true division like Python 3 for all numeric data. This means for SQL systems that use C-style division semantics, the appropriate CAST will be automatically inserted in the generated SQL.
Easier joins on tables with overlapping column names. See Ibis for SQL Programmers.
Expressions like string_expr[:3] now work as expected.
Add coalesce instance method to all value expressions.
Passing limit=None to the execute method on expressions disables any default row limits.
API Changes
ImpalaTable.rename no longer mutates the calling table expression.
