# 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:
```json

```
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),
subreddit_type Enum('public' = 1, 'restricted' = 2, 'user' = 3, 'archived' = 4, 'gold_restricted' = 5, 'private' = 6),
author LowCardinality(String),
body String CODEC(ZSTD(6)),
created_date Date DEFAULT toDate(created_utc),
created_utc DateTime,
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),
author_created_utc DateTime,
author_fullname LowCardinality(String),
author_patreon_flair UInt8,
author_premium UInt8,
can_gild UInt8,
can_mod_post UInt8,
collapsed UInt8,
is_submitter UInt8,

no_follow UInt8,
send_replies UInt8,
stickied UInt8,
author_flair_text LowCardinality(String)
)
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)─┐
│ 91613 │
└──────────────────────┘
1 row in set. Elapsed: 1.572 sec. Processed 85.97 million rows, 367.43 MB (54.71 million rows/s., 233.80 MB/s.)
```
5. This query returns the top 10 subreddits (in terms of number of comments):
```sql
SELECT
subreddit,
count() AS c
FROM reddit
GROUP BY subreddit
ORDER BY c DESC
LIMIT 20;
```
```response

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
┌─firstOfMonth─┬─────────c─┬─bar_count─────────────────┬─authors─┬─bar_authors───────────────┬─subreddits─┬─bar_subreddits────────────┐

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

sum(if(positionCaseInsensitive(body, 'clickhouse') > 0, 1, 0)) AS clickhouse,
sum(if(positionCaseInsensitive(body, 'snowflake') > 0, 1, 0)) AS snowflake,

# 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 Named collections can be configured with DDL or in configuration files and are applied
in configuration files and thus simplify the creation of objects and hide credentials when ClickHouse starts. They simplify the creation of objects and the hiding of credentials
from users with only SQL access. from users without administrative access.
Parameters can be set in XML `<format>CSV</format>` and overridden in SQL `, format = 'TSV'`. The keys in a named collection must match the parameter names of the corresponding
The parameters in SQL can be overridden using format `key` = `value`: `compression_method = 'gzip'`. 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: ## Storing named collections in the system database
```xml
$ cat /etc/clickhouse-server/config.d/named_collections.xml ### 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> <clickhouse>
<named_collections> <named_collections>
... <name>
<key_1>value</key_1>
<key_2>value_2</key_2>
<url>https://connection.url/</url>
</name>
</named_collections> </named_collections>
</clickhouse> </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
```
## Named collections for accessing S3
The description of parameters see [s3 Table Function](../sql-reference/table-functions/s3.md). The description of parameters see [s3 Table Function](../sql-reference/table-functions/s3.md).

This table does not exist if ZooKeeper is not configured. The 'system.zookeeper_connection' table shows current connections to ZooKeeper (including auxiliary ZooKeepers). Each row shows information about one connection.
Columns:
- `name` ([String](../../sql-reference/data-types/string.md)) — ZooKeeper cluster's name.
- `host` ([String](../../sql-reference/data-types/string.md)) — The hostname/IP of the ZooKeeper node that ClickHouse connected to.
- `port` ([String](../../sql-reference/data-types/string.md)) — The port of the ZooKeeper node that ClickHouse connected to.
- `index` ([UInt8](../../sql-reference/data-types/int-uint.md)) — The index of the ZooKeeper node that ClickHouse connected to. The index is from ZooKeeper config.
- `connected_time` ([String](../../sql-reference/data-types/string.md)) — When the connection was established
- `is_expired` ([UInt8](../../sql-reference/data-types/int-uint.md)) — Is the current connection expired.
