Twitter uses snowflake IDs for tweets, direct messages, users, lists, and all other objects available over the API. [7] Discord also uses snowflakes, with their epoch set to the first second of the year 2015. [3] Instagram uses a modified version of the format, with 41 bits for a timestamp, 13 bits for a shard ID, and 10 bits for a sequence ...
Then 6 or 7 bits are replaced by fixed values, the 4-bit version (e.g. 0011 2 for version 3), and the 2- or 3-bit UUID "variant" (e.g. 10 2 indicating a RFC 9562 UUIDs, or 110 2 indicating a legacy Microsoft GUID). Since 6 or 7 bits are thus predetermined, only 121 or 122 bits contribute to the uniqueness of the UUID.

The graphic showing "Components of a snowflake identifier in binary" differs from its source (where sequence and worker ID are swapped, and more annotations exist), and also does not actually show components in binary, given the fact each box seems to represent 2 bits. --2.204.112.236 10:20, 21 February 2022 (UTC)

The snowflake schema is in the same family as the star schema logical model. In fact, the star schema is considered a special case of the snowflake schema. The snowflake schema provides some advantages over the star schema in certain situations, including: Some OLAP multidimensional database modeling tools are optimized for snowflake schemas. [3]
The template accepts a single positional parameter and returns a timestamp based on the ID passed. The timestamp is by default in the format of "January 1, 2021", but if |format=dmy is passed, it's instead presented as "1 January 2021".
