It's not meant for driving, FLVS driver's ed, insurance, or any other official use. The system will generate the key pair, and display the key fingerprint and a randomart image. Open your file browser. Navigate to C: Users yourusername.ssh. You should see two files. The identification is saved in the idrsa file and the public key is labeled idrsa.pub. This is your SSH key pair.

I was recently working on an application that had a sharded MySQL database. While working on this application, I needed to generate unique IDs that could be used as the primary keys in the tables.

When you’re working with a single MySQL database, you can simply use an auto-increment ID as the primary key, But this won’t work in a sharded MySQL database.

So I looked at various existing solutions for this, and finally wrote a simple 64-bit unique ID generator that was inspired by a similar service by Twitter called Twitter snowflake.

In this article, I’ll share a simplified version of the unique ID generator that will work for any use-case of generating unique IDs in a distributed environment, not just sharded databases.

I’ll also outline other existing solutions and discuss their pros and cons.

Existing Solutions

UUID

UUIDs are 128-bit hexadecimal numbers that are globally unique. The chances of the same UUID getting generated twice is negligible.

The problem with UUIDs is that they are very big in size and don’t index well. When your dataset increases, the index size increases as well and the query performance takes a hit.

MongoDB’s ObjectId

MongoDB’s ObjectIDs are 12-byte (96-bit) hexadecimal numbers that are made up of -

a 4-byte epoch timestamp in seconds,
a 3-byte machine identifier,
a 2-byte process id, and
a 3-byte counter, starting with a random value.

This is smaller than the earlier 128-bit UUID. But again the size is relatively longer than what we normally have in a single MySQL auto-increment field (a 64-bit bigint value).

Database Ticket Servers

This approach uses a centralized database server to generate unique incrementing IDs. It’s like a centralized auto-increment. This approach is used by Flickr.

The problem with this approach is that the ticket server can become a write bottleneck. Moreover, you introduce one more component in your infrastructure that you need to manage and scale.

Key Generator For Machine Idle

Twitter Snowflake

Twitter snowflake is a dedicated network service for generating 64-bit unique IDs at high scale. The IDs generated by this service are roughly time sortable.

The IDs are made up of the following components:

Epoch timestamp in millisecond precision - 41 bits (gives us 69 years with a custom epoch)
Configured machine id - 10 bits (gives us up to 1024 machines)
Sequence number - 12 bits (A local counter per machine that rolls over every 4096)

The extra 1 bit is reserved for future purposes. Since the IDs use timestamp as the first component, they are time sortable.

The IDs generated by twitter snowflake fits in 64-bits and are time sortable, which is great. That’s what we want.

But If we use Twitter snowflake, we’ll agai
