Snowflake IDs, or snowflakes, are a form of unique identifier used in distributed computing. The format was created by Twitter (now X) and is used for the IDs of tweets. [ 1 ] It is popularly believed that every snowflake has a unique structure, so they took the name "snowflake ID".
On the one hand, 40 bits allow about 1 trillion domain/identifier values per node ID. On the other hand, with the clock value truncated to the 28 most significant bits, compared to 60 bits in version 1, the clock in a version 2 UUID will "tick" only once every 429.49 seconds, a little more than 7 minutes, as opposed to every 100 nanoseconds for ...
The tz database partitions the world into regions where local clocks all show the same time. This map was made by combining version 2023d with OpenStreetMap data, using open source software.
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".
