# Table Engines for Integrations
|
||||
|
||||
ClickHouse provides various means for integrating with external systems, including table engines. Like with all other table engines, the configuration is done using `CREATE TABLE` or `ALTER TABLE` queries. Then from a user perspective, the configured integration looks like a normal table, but queries to it are proxied to the external system. This transparent querying is one of the key advantages of this approach over alternative integration methods, like external dictionaries or table functions, which require to use custom query methods on each use.

Projections store data in a format that optimizes query execution, this feature is useful for:
|
||||
- Running queries on a column that is not a part of the primary key
|
||||
- Pre-aggregating columns, it will reduce both computation and IO
|
||||
|
||||
You can define one or more projections for a table, and during the query analysis the projection with the least data to scan will be selected by ClickHouse without modifying the query provided by the user.
|
||||
|
||||
## Example filtering without using primary keys
|
||||
|
||||
Creating the table:
|
||||
```
|
||||
CREATE TABLE visits_order
|
||||
(
|
||||
`user_id` UInt64,
|
||||
`user_name` String,
|
||||
`pages_visited` Nullable(Float64),
|
||||
`user_agent` String
|
||||
)
|
||||
ENGINE = MergeTree()
|
||||
PRIMARY KEY user_agent
|
||||
```
|
||||
Using `ALTER TABLE`, we could add the Projection to an existing table:
|
||||
```
|
||||
ALTER TABLE visits_order ADD PROJECTION user_name_projection (
|
||||
SELECT
|
||||
*
|
||||
ORDER BY user_name
|
||||
)
|
||||
|
||||
ALTER TABLE visits_order MATERIALIZE PROJECTION user_name_projection
|
||||
```
|
||||
Inserting the data:
|
||||
```
|
||||
INSERT INTO visits_order SELECT
|
||||
number,
|
||||
'test',
|
||||
1.5 * (number / 2),
|
||||
'Android'
|
||||
FROM numbers(1, 100);
|
||||
```
|
||||
|
||||
The Projection will allow us to filter by `user_name` fast even if in the original Table `user_name` was not defined as a `PRIMARY_KEY`.
|
||||
At query time ClickHouse determined that less data will be processed if the projection is used, as the data is ordered by `user_name`.
|
||||
```
|
||||
SELECT
|
||||
*
|
||||
FROM visits_order
|
||||
WHERE user_name='test'
|
||||
LIMIT 2
|
||||
```
|
||||
|
||||
To verify that a query is using the projection, we could review the `system.query_log` table. On the `projections` field we have the name of the projection used or empty if none has been used:
|
||||
```
|
||||
SELECT query, projections FROM system.query_log WHERE query_id='<query_id>'
|
||||
```
|
||||
|
||||
## Example pre-aggregation query
|
||||
|
||||
Creating the table with the Projection:
|
||||
```
|
||||
CREATE TABLE visits
|
||||
(
|
||||
`user_id` UInt64,
|
||||
`user_name` String,
|
||||
`pages_visited` Nullable(Float64),
|
||||
`user_agent` String,
|
||||
PROJECTION projection_visits_by_user
|
||||
(
|
||||
SELECT
|
||||
user_agent,
|
||||
sum(pages_visited)
|
||||
GROUP BY user_id, user_agent
|
||||
)
|
||||
)
|
||||
ENGINE = MergeTree()
|
||||
ORDER BY user_agent
|
||||
```
|
||||
Inserting the data:
|
||||
```
|
||||
INSERT INTO visits SELECT
|
||||
number,
|
||||
'test',
|
||||
1.5 * (number / 2),
|
||||
'Android'
|
||||
FROM numbers(1, 100);
|
||||
```
|
||||
```
|
||||
INSERT INTO visits SELECT
|
||||
number,
|
||||
'test',
|
||||
1. * (number / 2),
|
||||
'IOS'
|
||||
FROM numbers(100, 500);
|
||||
```
|
||||
We will execute a first query using `GROUP BY` using the field `user_agent`, this query will not use the projection defined as the pre-aggregation does not match.
|
||||
```
|
||||
SELECT
|
||||
user_agent,
|
||||
count(DISTINCT user_id)
|
||||
FROM visits
|
||||
GROUP BY user_agent
|
||||
```
|
||||
|
||||
To use the projection we could execute queries that select part of, or all of the pre-aggregation and `GROUP BY` fields.
|
||||
```
|
||||
SELECT
|
||||
user_agent
|
||||
FROM visits
|
||||
WHERE user_id > 50 AND user_id < 150
|
||||
GROUP BY user_agent
|
||||
```
|
||||
```
|
||||
SELECT
|
||||
user_agent,
|
||||
sum(pages_visited)
|
||||
FROM visits
|
||||
GROUP BY user_id
|
||||
```
|
||||
|
||||
As mentioned before, we could review the `system.query_log` table. On the `projections` field we have the name of the projection used or empty if none has been used:
|
||||
```
|
||||
SELECT query, projections FROM system.query_log WHERE query_id='<query_id>'
|
||||
```
