# Reddit comments dataset

This dataset contains publicly-available comments on Reddit that go back to December, 2005, to March, 2023, and contains over 7B rows of data. The raw data is in JSON format in compressed `.zst` files and the rows look like the following:

A shoutout to Percona for the [motivation behind ingesting this dataset](https://www.percona.com/blog/big-data-set-reddit-comments-analyzing-clickhouse/), which we have downloaded and stored in an S3 bucket.
|

|
||||
:::note
|
||||
The following commands were executed on ClickHouse Cloud. To run this on your own cluster, replace `default` in the `s3Cluster` function call with the name of your cluster. If you do not have a cluster, then replace the `s3Cluster` function with the `s3` function.

1. Let's create a table for the Reddit data:
|
||||
|
||||
```sql
|
||||
CREATE TABLE reddit
|
||||
(
|
||||
subreddit LowCardinality(String),
|
||||
subreddit_id LowCardinality(String),
|
||||

|
||||

|
||||
body String CODEC(ZSTD(6)),
|
||||

|
||||

|
||||
retrieved_on DateTime,
|
||||
id String,
|
||||
parent_id String,
|
||||
link_id String,
|
||||
score Int32,
|
||||
total_awards_received UInt16,
|
||||
controversiality UInt8,
|
||||
gilded UInt8,
|
||||
collapsed_because_crowd_control UInt8,
|
||||
collapsed_reason Enum('' = 0, 'comment score below threshold' = 1, 'may be sensitive content' = 2, 'potentially toxic' = 3, 'potentially toxic content' = 4),
|
||||
distinguished Enum('' = 0, 'moderator' = 1, 'admin' = 2, 'special' = 3),
|
||||
removal_reason Enum('' = 0, 'legal' = 1),
|
||||

|
||||

|
||||

|
||||
)
|
||||
ENGINE = MergeTree
|
||||
ORDER BY (subreddit, created_date, author);
|
||||
```
|
||||
|
||||
:::note
|
||||
The names of the files in S3 start with `RC_YYYY-MM` where `YYYY-MM` goes from `2005-12` to `2023-02`. The compression changes a couple of times though, so the file extensions are not consistent. For example:
|
||||
|
||||
- the file names are initially `RC_2005-12.bz2` to `RC_2017-11.bz2`
|
||||
- then they look like `RC_2017-12.xz` to `RC_2018-09.xz`
|
||||
- and finally `RC_2018-10.zst` to `RC_2023-02.zst`
|
||||
:::
|
||||
|
||||
2. We are going to start with one month of data, but if you want to simply insert every row - skip ahead to step 8 below. The following file has 86M records from December, 2017:
|
||||
|
||||
```sql
|
||||
INSERT INTO reddit
|
||||
SELECT *
|
||||
FROM s3Cluster(
|
||||
'default',
|
||||
'https://clickhouse-public-datasets.s3.eu-central-1.amazonaws.com/reddit/original/RC_2017-12.xz',
|
||||
'JSONEachRow'
|
||||
);
|
||||
```
|
||||
|
||||
If you do not have a cluster, use `s3` instead of `s3Cluster`:
|
||||
|
||||
```sql
|
||||
INSERT INTO reddit
|
||||
SELECT *
|
||||
FROM s3(
|
||||
'https://clickhouse-public-datasets.s3.eu-central-1.amazonaws.com/reddit/original/RC_2017-12.xz',
|
||||
'JSONEachRow'
|
||||
);
|
||||
```
|
||||
|
||||
3. It will take a while depending on your resources, but when it's done verify it worked:
|
||||
|
||||
```sql
|
||||
SELECT formatReadableQuantity(count())
|
||||
FROM reddit;
|
||||
```
|
||||
|
||||
```response
|
||||
┌─formatReadableQuantity(count())─┐
|
||||
│ 85.97 million │
|
||||
└─────────────────────────────────┘
|
||||

4. Let's see how many unique subreddits were in December of 2017:
|
||||
|
||||
```sql
|
||||
SELECT uniqExact(subreddit)
|
||||
FROM reddit;
|
||||
```
|
||||
|
||||
```response
|
||||
┌─uniqExact(subreddit)─┐

|
||||
└──────────────────────┘

|
||||
```
|
||||
|
||||
5. This query returns the top 10 subreddits (in terms of number of comments):
|
||||
|
||||
```sql
|
||||
SELECT
|
||||
subreddit,
|
||||
count() AS c
|
||||

6. Here are the top 10 authors in December of 2017, in terms of number of comments posted:
|
||||
|
||||
```sql
|

|

7. We already inserted some data, but we will start over:
|
||||
|
||||
```sql
|
||||
TRUNCATE TABLE reddit;
|
||||
```
|
||||
|
||||
8. This is a fun dataset and it looks like we can find some great information, so let's go ahead and insert the entire dataset from 2005 to 2023. When you're ready, run this command to insert all the rows. (It takes a while - up to 17 hours!)
|
||||
|
||||
```sql
|
||||
INSERT INTO reddit
|
||||
SELECT *
|
||||
FROM s3Cluster(
|
||||
'default',
|
||||
'https://clickhouse-public-datasets.s3.amazonaws.com/reddit/original/RC*',
|
||||
'JSONEachRow'
|
||||
)
|
||||
SETTINGS zstd_window_log_max = 31;
|
||||
```
|
||||
|
||||
The response looks like:
|
||||
|
||||
```response
|
||||
0 rows in set. Elapsed: 61187.839 sec. Processed 6.74 billion rows, 2.06 TB (110.17 thousand rows/s., 33.68 MB/s.)
|
||||
```
|
||||
|
||||
8. Let's see how many rows were inserted and how much disk space the table is using:
|
||||
|
||||
|
||||
```sql
|
||||
SELECT
|
||||
sum(rows) AS count,
|
||||
formatReadableQuantity(count),
|
||||
formatReadableSize(sum(bytes)) AS disk_size,
|
||||
formatReadableSize(sum(data_uncompressed_bytes)) AS uncompressed_size
|
||||
FROM system.parts
|
||||
WHERE (table = 'reddit') AND active
|
||||
```
|
||||
|
||||
Notice the compression of disk storage is about 1/3 of the uncompressed size:
|
||||
|
||||
```response
|
||||
┌──────count─┬─formatReadableQuantity(sum(rows))─┬─disk_size──┬─uncompressed_size─┐
|
||||
│ 6739503568 │ 6.74 billion │ 501.10 GiB │ 1.51 TiB │
|
||||
└────────────┴───────────────────────────────────┴────────────┴───────────────────┘
|
||||
|
||||
1 row in set. Elapsed: 0.010 sec.
|
||||
```
|
||||
|
||||
9. The following query shows how many comments, authors and subreddits we have for each month:
|
||||
|
||||
```sql
|
||||
SELECT
|
||||
toStartOfMonth(created_utc) AS firstOfMonth,
|
||||
count() AS c,
|
||||
bar(c, 0, 50000000, 25) AS bar_count,
|
||||
uniq(author) AS authors,
|
||||
bar(authors, 0, 5000000, 25) AS bar_authors,
|
||||
uniq(subreddit) AS subreddits,
|
||||
bar(subreddits, 0, 100000, 25) AS bar_subreddits
|
||||
FROM reddit
|
||||
GROUP BY firstOfMonth
|
||||
ORDER BY firstOfMonth ASC;
|
||||
```
|
||||
|
||||
This is a substantial query that has to process all 6.74 billion rows, but we still get an impressive response time (about 3 minutes):
|
||||
|
||||
```response
|
||||

11. Let's see which subreddits had the biggest increase in commnents from 2018 to 2019:
|
||||
|
||||
```sql
|
||||
SELECT
|
||||
subreddit,
|
||||
newcount - oldcount AS diff
|
||||
FROM
|
||||
(

|

subreddit,

|

|
||||
WHERE toYear(created_utc) = 2019
|
||||
GROUP BY subreddit
|
||||
)
|
||||
ALL INNER JOIN
|
||||
(
|
||||
SELECT
|
||||
subreddit,
|
||||
count(*) AS oldcount
|
||||
FROM reddit
|
||||
WHERE toYear(created_utc) = 2018
|
||||
GROUP BY subreddit
|
||||
) USING (subreddit)
|
||||
ORDER BY diff DESC
|
||||
LIMIT 50
|
||||
SETTINGS joined_subquery_requires_alias = 0;
|
||||
```
|
||||
|
||||
It looks like memes and teenagers were busy on Reddit in 2019:

12. One more query: let's compare ClickHouse mentions to other technologies like Snowflake and Postgres. This query is a big one because it has to search all the comments three times for a substring, and unfortunately ClickHouse user are obviously not very active on Reddit yet:
|
||||
|
||||
```sql
|
||||
SELECT
|
||||
toStartOfQuarter(created_utc) AS quarter,
|
||||
sum(if(positionCaseInsensitive(body, 'clickhouse') > 0, 1, 0)) AS clickhouse,
|
||||
sum(if(positionCaseInsensitive(body, 'snowflake') > 0, 1, 0)) AS snowflake,
|
||||
sum(if(positionCaseInsensitive(body, 'postgres') > 0, 1, 0)) AS postgres
|
||||
FROM reddit
|
||||
GROUP BY quarter
|
||||
ORDER BY quarter ASC;
|
||||
```

# Storing details for connecting to external sources in configuration files
|
||||
Named collections provide a way to store collections of key-value pairs to be
|
||||
used to configure integrations with external sources. You can use named collections with
|
||||
dictionaries, tables, table functions, and object storage.
|
||||
|
||||
Details for connecting to external sources (dictionaries, tables, table functions) can be saved
|
||||
in configuration files and thus simplify the creation of objects and hide credentials
|
||||
from users with only SQL access.
|
||||
Named collections can be configured with DDL or in configuration files and are applied
|
||||
when ClickHouse starts. They simplify the creation of objects and the hiding of credentials
|
||||
from users without administrative access.
|
||||
|
||||
Parameters can be set in XML `<format>CSV</format>` and overridden in SQL `, format = 'TSV'`.
|
||||
The parameters in SQL can be overridden using format `key` = `value`: `compression_method = 'gzip'`.
|
||||
The keys in a named collection must match the parameter names of the corresponding
|
||||
function, table engine, database, etc. In the examples below the parameter list is
|
||||
linked to for each type.
|
||||
|
||||
Named collections are stored in the `config.xml` file of the ClickHouse server in the `<named_collections>` section and are applied when ClickHouse starts.
|
||||
Parameters set in a named collection can be overridden in SQL, this is shown in the examples
|
||||
below.
|
||||
|
||||
Example of configuration:
|
||||
```xml
|
||||
$ cat /etc/clickhouse-server/config.d/named_collections.xml
|
||||
## Storing named collections in the system database
|
||||
|
||||
### DDL example
|
||||
|
||||
```sql
|
||||
CREATE NAMED COLLECTION name AS
|
||||
key_1 = 'value',
|
||||
key_2 = 'value2',
|
||||
url = 'https://connection.url/'
|
||||
```
|
||||
|
||||
### Permissions to create named collections with DDL
|
||||
|
||||
To manage named collections with DDL a user must have the `named_control_collection` privilege. This can be assigned by adding a file to `/etc/clickhouse-server/users.d/`. The example gives the user `default` both the `access_management` and `named_collection_control` privileges:
|
||||
|
||||
```xml title='/etc/clickhouse-server/users.d/user_default.xml'
|
||||
<clickhouse>
|
||||
<users>
|
||||
<default>
|
||||
<password_sha256_hex>65e84be33532fb784c48129675f9eff3a682b27168c0ea744b2cf58ee02337c5</password_sha256_hex replace=true>
|
||||
<access_management>1</access_management>
|
||||
<!-- highlight-start -->
|
||||
<named_collection_control>1</named_collection_control>
|
||||
<!-- highlight-end -->
|
||||
</default>
|
||||
</users>
|
||||
</clickhouse>
|
||||
```
|
||||
|
||||
:::tip
|
||||
In the above example the `passowrd_sha256_hex` value is the hexadecimal representation of the SHA256 hash of the password. This configuration for the user `default` has the attribute `replace=true` as in the default configuration has a plain text `password` set, and it is not possible to have both plain text and sha256 hex passwords set for a user.

## Storing named collections in configuration files
|
||||
|
||||
### XML example
|
||||
|
||||
```xml title='/etc/clickhouse-server/config.d/named_collections.xml'

||||
<clickhouse>

## Named collections for accessing S3.
|
||||
## Modifying named collections
|
||||
|
||||
Named collections that are created with DDL queries can be altered or dropped with DDL. Named collections created with XML files can be managed by editing or deleting the corresponding XML.
|
||||
|
||||
### Alter a DDL named collection
|
||||
|
||||
Change or add the keys `key1` and `key3` of the collection `collection2`:
|
||||
```sql
|
||||
ALTER NAMED COLLECTION collection2 SET key1=4, key3='value3'
|
||||
```
|
||||
|
||||
Remove the key `key2` from `collection2`:
|
||||
```sql
|
||||
ALTER NAMED COLLECTION collection2 DELETE key2
|
||||
```
|
||||
|
||||
Change or add the key `key1` and delete the key `key3` of the collection `collection2`:
|
||||
```sql
|
||||
ALTER NAMED COLLECTION collection2 SET key1=4, DELETE key3
|
||||
```
|
||||
|
||||
### Drop the DDL named collection `collection2`:
|
||||
```sql
|
||||
DROP NAMED COLLECTION collection2
|
||||
```

可以使用`*` 号代替表或库名进行授权操作。例如， `GRANT SELECT ONdb.* TO john` 操作运行 `john`对 `db`库的所有表执行 `SELECT`查询。同样，你可以忽略库名。在这种情形下，权限将指向当前的数据库。例如， `GRANT SELECT ON* to john` 对当前数据库的所有表指定授权， `GARNT SELECT ON mytable to john`对当前数据库的 `mytable`表进行授权。
