## "Extended" Queries
The "extended" queries are not part of the official ClickBench benchmark.
Instead they are used to test other DataFusion features that are not
covered by the standard benchmark

Each description below is for the corresponding line in `extended.sql` (line 1
is `Q0`, line 2 is `Q1`, etc.)

### Q0: Data Exploration

**Question**: "How many distinct searches, mobile phones, and mobile phone models are there in the dataset?"

**Important Query Properties**: multiple `COUNT DISTINCT`s, with low and high cardinality
distinct string columns.

```sql
SELECT COUNT(DISTINCT "SearchPhrase"), COUNT(DISTINCT "MobilePhone"), COUNT(DISTINCT "MobilePhoneModel")
FROM hits;
```


### Q1: Data Exploration

**Question**: "How many distinct "hit color", "browser country" and "language" are there in the dataset?"

**Important Query Properties**: multiple `COUNT DISTINCT`s. All three are small strings (length either 1 or 2).

### Q0
Models initial Data exploration, to understand some statistics of data.
Import Query Properties: multiple `COUNT DISTINCT` on strings

```sql
SELECT
COUNT(DISTINCT "SearchPhrase"), COUNT(DISTINCT "MobilePhone"), COUNT(DISTINCT "MobilePhoneModel")
SELECT COUNT(DISTINCT "HitColor"), COUNT(DISTINCT "BrowserCountry"), COUNT(DISTINCT "BrowserLanguage")
FROM hits;
```

### Q2: Top 10 anaylsis

**Question**: "Find the top 10 "browser country" by number of distinct "social network"s,
including the distinct counts of "hit color", "browser language",
and "social action"."

**Important Query Properties**: GROUP BY short, string, multiple `COUNT DISTINCT`s. There are several small strings (length either 1 or 2).

```sql
SELECT "BrowserCountry", COUNT(DISTINCT "SocialNetwork"), COUNT(DISTINCT "HitColor"), COUNT(DISTINCT "BrowserLanguage"), COUNT(DISTINCT "SocialAction")
FROM hits
GROUP BY 1
ORDER BY 2 DESC
LIMIT 10;
```


## Data Notes

Here are some interesting statistics about the data used in the queries
Max length of `"SearchPhrase"` is 1113 characters
```sql
❯ select min(length("SearchPhrase")) as "SearchPhrase_len_min", max(length("SearchPhrase")) "SearchPhrase_len_max" from 'hits.parquet' limit 10;
+----------------------+----------------------+
| SearchPhrase_len_min | SearchPhrase_len_max |
+----------------------+----------------------+
| 0 | 1113 |

```
