create_if_not_exists As a Setting
+
+
A usual way:
+
+
CREATE TABLE IF NOT EXISTS test (x UInt8) ORDER BY ();
+
+
+
A new option, since 24.9:
+
+
SET create_if_not_exists = 1;
+
+CREATE TABLE test (x UInt8) ORDER BY ();
+
+
+
— "out of band" if not exists specification as a setting.

New Functions overlay, overlayUTF8
+

Replaces a fragment in a string with another string in a specified position.
+
+

+1. │ Hello, test! │

+
+
+
input_format_json_empty_as_default
+
+
But you will rarely need it:
+
+
— omitted fields in JSON are interpreted as default;
+
— input_format_null_as_default is also enabled,
+ and nulls in JSON will be interpreted as default;
+
+
The new setting, input_format_json_empty_as_default is for rare cases when an empty string should be mapped to the default expression.
+
+
+
+
+
+
DELETE ... IN PARTITION
+
+
DELETE FROM test IN PARTITION 202409 WHERE data LIKE '%trash%'
+
+
An option for DELETE query to explicitly limit it for a specified partition.
+
+
It avoids copying parts metadata for unrelated partitions.
+
+
Developer: Sunny.
+
+
+
+
+
system.projections
+
+
A table in ClickHouse can contain "projections" — they represent the same data in a different physical order or an aggregation, to automatically optimize queries by using this data.
+
+
CREATE TABLE hits (CounterID UInt32, URL String
+PROJECTION totals (SELECT CounterID, count(), uniq(URL) GROUP BY CounterID)
+) ENGINE = MergeTree ORDER BY (CounterID, EventTime);
+
+
+
A new system table to introspect projections.

_headers Column For URL Engine
+
+
Obtain a dictionary of HTTP response headers when querying a remote server.
— enables virtual columns from the paths: type, year, quarter
+ and automatically infers their types.
+
+
ClickHouse 24.9:
+
+

Something Interesting
+
+
+
+
Iceberg On Azure And Local
+
+
In version 24.8, Iceberg tables were supported only for S3.
+
+
In version 24.9, it is supported for Azure Blob storage
+ and local filesystem.
+
+
Now there are IcebergS3, IcebergAzure, and IcebergLocal table engines,
+ as well as icebergS3, icebergAzure, and icebergLocal table functions.
+

Multiple Credentials For a User

+
-- create a user with two alternative passwords:
+CREATE USER test IDENTIFIED
+ BY 'abc' VALID UNTIL '2024-10-01',
+ BY 'def' VALID UNTIL '2024-11-01';
+
+-- create a user with multiple authentication methods:
+CREATE USER test IDENTIFIED

+ WITH ssh_key BY KEY '...' TYPE 'ssh-ed25519';
+
+-- add a new method:

APPEND For Refreshable Materialized Views 🧪
+
+
CREATE MATERIALIZED VIEW [IF NOT EXISTS] [db.]table_name
+ REFRESH EVERY|AFTER interval [OFFSET interval]
+ RANDOMIZE FOR interval
+ DEPENDS ON [db.]name [, [db.]name [, ...]]
+ [APPEND] [TO [db.]name] [(columns)] [ENGINE = engine]
+ AS SELECT ...
+
+
+
Refreshable Materialized Views exist since 23.11.
+
The APPEND mode is new in 24.9.
+
+
Developer: Michael Kolupaev.
+
+
+
+
APPEND For Refreshable Materialized Views 🧪
+
+
Run the SELECT query in background and atomically
+replace or append to the table with its result.
+
Run the refresh process using a flexible configured schedule.
+
Support a dependency graph with multiple materialized views.
+
+
Example: periodically request an external API with the url table function
+ and keep accumulating results in a table.
+
+
+
+
+
Developer: Michael Kolupaev.
+
+
+
+
Variant Types In Schema Inference 🧪
+
+
Now ClickHouse supports automatic usage of the Variant data type
+ for schema inference.
SELECT DISTINCT arrayJoin(JSONAllPaths(data)) FROM website_traffic;
+
+SELECT distinctJSONPaths(data) FROM website_traffic;
