We already have some scripts in the scripts directory. It would be good to run them for every PR.
This is also a great task for beginners.

Sometimes it is needed to store compressed data in the DB. Unfortunately not all the DBs have built-in compression and FUSE compressed FSes are not available for every OS. So it may make sense to store compressed binary blobs in the DB.

Unfortunately when one sees them in DBeaver he sees them compressed, but often they are needed uncompressed. So it'd be nice to have a feature to decompress the

If I create any model with
charset: 'utf8mb4', collate: 'utf8mb4_general_ci'

sequelize translates it to this for mysql

CREATE TABLE IF NOT EXISTS tablename ... ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE utf8mb4_general_ci;

On stepping through the code, it seems that the issu

In a support escalation (https://github.com/cockroachlabs/support/issues/1709) for a v21.1 cluster, we saw that leaked gossip entries could impact foreground latency. The gossip leak itself has [since been fixed](cockroachdb/cockroach@d07b32db3e49e

Describe the Bug

If the user is in a role that only has permission to view Button links - this button is not clickable. It is necessary to grant editing permission to be able to click on the link that redirect to the right place.

To Reproduce

Create button links in the collection, make some role read-only and try to click. The situation will change if you allow editing even if the condi

Currently we only support Upsert for CockroachDB. Implementing same for MySQL should be pretty straightforward as well.

Wonder if we can also use INSERT ON CONFLICT UPDATE for PostgreSQL to ensure operation with same signature also works.

Describe the bug
Using a time dimension on a runningTotal measure on Snowflake mixes quoted and unquoted columns in the query. This fails the query, because Snowflake has specific rules about quoted columns. Specifically:

• All unquoted column names are treated as upper case
• Quoted column names are case sensitive.

So "date_from" <> date_from

To Reproduce
Steps to reproduce

Currently, when you clone a single branch from a Dolt database, you get only that single branch, but you still get remote tracking branches for the other branches in the remote database. To follow Git's semantics, we should not be creating those remote tracking branches for other branches.

with the implementation of copy to clipboard it would be very useful to have the option to copy with this pattern below (which I don't remember the name at this time)

We have users periodically asking for week-based partitioning.

Describe the solution you'd like.

Add WEEK to the PARTITION BY options.

안녕하세요

자료 보면서 공부하다가 counting sort 코드가 이상한 부분이 있어서 수정했습니다

1. 과정 3에서 누적합을 만들어줄 때 arr.length -> counting.length
2. 과정 4에서 다시 sorted_arr에 넣어줄 때 인덱스가 counting[arr[i]] -> counting[arr[i]] - 1

좋은자료 항상 감사합니다 :)
