Hybrid Tables
2 minute read
Introduction
Snowflake Hybrid tables, also known as Unistore hybrid tables, support fast, single-row operations by enforcing unique constraints for required primary keys and including indexes to speed up data retrieval. These tables are designed to optimize support for both analytical and transactional workloads simultaneously, underpinning Snowflake’s Unistore architecture.
The Snowflake emulator supports Hybrid tables, allowing you to create and manage Hybrid tables locally. The following operations are supported:
Getting started
This guide is designed for users new to Hybird tables and assumes basic knowledge of SQL and Snowflake. Start your Snowflake emulator and connect to it using an SQL client in order to execute the queries further below.
In this guide, you will create a Hybrid table, display the Hybrid tables, and drop the Hybrid table.
Create a Hybrid table
You can create a Hybrid table using the CREATE HYBRID TABLE statement. In this example, you can create a Hybrid table called test-table:
CREATE HYBRID TABLE "test-table"(id int, name TEXT, PRIMARY KEY(id));
The output should be:
+------------------------------------------+
| status |
|------------------------------------------|
| Table "test-table" successfully created. |
+------------------------------------------+
Show Hybrid tables
You can display the Hybrid tables using the SHOW HYBRID TABLES statement:
SHOW HYBRID TABLES LIKE 'test-table';
The output should be:
+-----------------------------------------------------------------------------------------------------+
created_on |name |database_name|schema_name|comment|rows|bytes|owner |owner_role_type|
-----------------------+----------+-------------+-----------+-------+----+-----+------+---------------+
1970-01-01 05:30:00.000|test-table|TEST |PUBLIC | |1000| 1000|PUBLIC|ROLE |
+-----------------------------------------------------------------------------------------------------+
Drop Hybrid table
You can drop the Hybrid table using the DROP HYBRID TABLE statement:
DROP TABLE "test-table";
The output should be:
+------------------------------------------+
| status |
| -----------------------------------------+
| TEST-TABLE successfully dropped. |
+------------------------------------------+
