A database is a structured set of data held in a computer, most often a server. Databases use a database management system (DBMS) that interacts with users, similar to a lookup table. Modern databases are designed to allow for creation, querying, updating, and administration of the data it holds.

Describe the bug
When the elevated database user account does not have permission to create a schema, it cannot establish a connection with an existing database.
But when I provided the root account, I successfully established a connection with the database, but prisma created a schema called prisma.
Look like this:

query having eq function in condition, gives weird error message.
Example query:
upsert {
query {
me(func: eq(name, "Animesh")) {
u as uid
n as name
}
}
mutation @if(eq(n, "Animesh")) {
set {
uid(u) <name> "Ashish" .
}
}
}
Example error:

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

There appears to be a race condition....
If you are trying to do a: user.auth(pair) then user.get.put; user.leave
Then it works if, and only if, you wait for the ack on the put,
If you don't wait for the ack, then you get a "No! Unverified Data" message, probably because with Gun's state its no longer logged in.
Personally ... I think its a bug/design flaw that Gun uses state in the g

Multi-line queries have a prompt_continuation (or not currently, due to issue 681, but that's beside the point). But even with prompt_continuation set to an empty string, it starts the next line indented, even when it's just due to wrapping at the edge of the terminal window:

Always to test tidb performance by POC,sometimes we will use the production data,sometimes we can use public dataset such as ONTIME,like percona. the Genaral data format is CSV,could you provide an example like Percona-lab which used for TiDB.
