Working on a project I ran into the documentation for customizing the Foreign Key.
The docs read:
// https://sequelize.org/master/manual/assocs.html
// For example, to use UUID as the foreign key data type instead of the default (INTEGER), you can simply do:
const { DataTypes } = require("Sequelize");
Foo.hasOne(Bar, {
foreignKey: {
// name: 'myFooId'
type: D
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

Add basic CI
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.

In https://github.com/taosdata/TDengine/blob/develop/src/client/src/tscPrepare.c, Local variable loopCont is assigned only once, to a constant value, making it effectively constant throughout its scope. If this is not the intent, examine the logic to see if there is a missing assignment that would make loopCont not remain constant.
So the 1567th line should be removed.

Hi,
my admin portal looks like this :
Version
- Server Installed 1.38.4
- Server Latest 1.38.4
- Web Installed -
- Web Latest 2.17.1
It seems that, at some point, 'GetInstalledWebVersion()' in 'Admin.dll' is called? Could anyone help me understand what do I need to check, to fix this?

Describe the bug
Currently keys written to server.conf
go undetected.
This means that not only typos go undetected, but lack of validation is a risk during version migration as settings that used to apply in a previous version have no effect in a newer one without warning -- even if new settings are supposed to be used.
To reproduce
- Create a key with a typo.
- Watch the QuestDB

- When using time travel, we don’t know where to get the transaction number from - we should show this to the user after committing data (this may be a missing capability in immudb / tools).
- The last long query example in the quick start is incorrect (incorrect
