The usage of Snowflake and the analysis of examples

The use of Snowflake and example analysis, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can gain something.

Snowflake algorithm-Snowflake

Snowflake, Snowflake algorithm is a distributed ID generation algorithm open source by Twitter, which divides the 64-bit bit into multiple parts by dividing the namespace, each part represents a different meaning. The integer of 64bit in Java is of type Long, so the ID generated by SnowFlake algorithm in Java is stored by long.

The first bit occupies 1bit, and its value is always 0, which can be seen as the symbol bit is not used.

The first 41 bits of the second bit are timestamps, and the 41-bit bit can represent 2 ^ 41 numbers, each representing milliseconds, so the available time of the snowflake algorithm is (1L).
