Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Sequential UUID in snowflake
Snowflake does not support UUID 7. What you could do is import UUID7 Python module and implement a Python UDF.

Understanding UUIDs, ULIDs and String Representations
To summarise the differences:
* UUIDv6 - sortable, with a layout matching UUIDv1 for backward compatibility, except the time chunks have been reordered so the uuid sorts chronologically
* UUIDv7 - sortable, based on nanoseconds since the Unix epoch. Simpler layout than UUIDv6 and more flexibility about the number of bits allocated to the time part versus sequence and randomness. The nice aspect here is the uuids sort chronologically even when created by systems using different numbers of time bits.
* UUIDv8 - more flexibility for layout. Should only be used if UUIDv6/7 aren't suitable. Which of course makes them specific to that one application which knows how to encode/decode them.
UUIDv7 is thus the better choice in general.
(I recently wrote Python and C# implementations - https://github.com/stevesimmons/uuid7 and https://github.com/stevesimmons/uuid7-csharp)

New UUID Formats from IETF
I made a simple Python test library that extends the standard UUID class with UUIDv6 and UUIDv7. You might want to check it out. https://github.com/oittaa/uuid6-python
The official UUID Draft repository has also some alternatives if you'd like to check those out. https://github.com/uuid6/prototypes
Postgres supports UUIDs with any version number natively so you can then do something like this with it:
create table data (id uuid, firstname varchar(100));
What are some alternatives?
uuid7-csharp - UUIDv7 for C#. Time-ordered UUIDs with up to 50ns resolution and 48 bits of randomness.
vanity-uuid - Create "readable" UUIDs such as "5eedbed5-f05e-b055-ada0-d15ab11171e5" for all your UUID needs!
ksuid - K-Sortable Globally Unique IDs
dart-uuid - Generate RFC4122(v1,v4,v5,v6,v7,v8) UUIDs
Hashids.java - Hashids algorithm v1.0.0 implementation in Java
uuid - Generate and parse UUIDs.
uuid6-ietf-draft - Next Generation UUID Formats
typeid-python - Python implementation of TypeIDs: type-safe, K-sortable, and globally unique identifiers inspired by Stripe IDs
presents - Like hashids, but based on block ciphers
ulid - Universally Unique Lexicographically Sortable Identifier (ULID) in Python 3
