海外TECH	DEV Community	The life-changing magic of SurrealDB - record IDs	https://dev.to/surrealdb/the-life-changing-magic-of-surrealdb-record-ids-58li	The life changing magic of SurrealDB record IDsAt SurrealDB we are all about doing things that spark joy for developers One of those things that constantly surprises and delights is the humble record ID which we discussed in our live stream Far from being just a boring number your queries can be magical Without further ado then let s learn some surreal magic The look and feelThe first thing to be aware of is that in SurrealDB a record ID has two parts a table name and a record identifier which looks like this table record By default when you create a table create internet a random id is assigned This differs from the traditional default of auto increment or serial IDs you might be used to This allows you to avoid common problems such as Impact on the concurrency and scalability of your database Accidental information disclosure through using IDs in URLs giving away data size and velocity Non uniqueness across tables or table shards across distributed nodesThe typical solution to this is to use cryptographically secure randomly generated identifiers such as our default rand but you can also use ulid and uuid In a nutshell we want to make it as easy as possible to fall into the pit of success where the default option works well as you scale Let s step back a bit and look at the simplest example of comparing SQL and SurrealQL where we select one id from a table SQLselect from internetwhere id Just a completely run of the mill example nothing special about it SurrealQLselect from internet leetHere we can see something new We can filter to a record right from the from statement This would be the shorthand example for select from internetwhere id internet leetNow let s step it up a bit What if we needed to select a range of ids SQL Over select from internetwhere id gt less than select from internetwhere id lt between and select from internetwhere id gt and id lt SurrealQL Over select from internet less than select from internet between and select from internet However this is much more than just some syntactic sugar To understand why we need to talk a bit about algorithmic complexity don t worry It s not that complicated The performance at scaleIn the simplest of terms an algorithm is just a recipe for a sequence of steps do this then that Therefore algorithmic complexity often talked about in terms of asymptotic big O notation is just a way to estimate how many steps are likely to be in the sequence The fewer steps the better With SurrealQL when doing CRUD with a record ID you don t have to do a table scan which gets slower the more data you have This is because the algorithm most databases use for this is O log n instead of the O key value lookup in SurrealDB which has near constant performance regardless of scale This makes working with IDs extremely fast as you scale and opens up new use cases The flexibilityNow it s time for some real magic It s time to free your mind and rethink what is possible with an ID SurrealDB s Complex Record IDs support dynamic expressions allowing parameters and function expressions to be used as values within the IDs This is useful in various ways such as a time series context or ensuring locality between specific records in a table Effectively creating clustered indexes amp partitions naturally in your data as you scale with the performance of the ID lookup regardless of size While this does not replace traditional indexes or partitions for your data it offers additional flexibility to model the data in a performant way Let s look at an example of creating Object based Record IDs Set a new parameterLET now time now Create a record with a complex ID using an objectCREATE temperature location London date now SET location London date now temperature You can also create Array based Record IDs Set a new parameterLET now time now Create a record with a complex ID using an arrayCREATE temperature London now SET location London date now temperature Which you can query like this Select all records for a particular location inclusiveSELECT FROM temperature London NONE London time now Select all temperature records with IDs between the specified rangeSELECT FROM temperature London T London T As you can see pretty much the only limit to what a record ID can be is your imagination The futureWe have just scratched the surface of what you can do with record IDs If you want to dig deeper take a look at our stream about Record IDs featuring even more powerful capabilities or check out our documentation If this has sparked some ideas perhaps something you ve always wanted was possible we d love to hear from you You ll find us at all the usual places including our discord and GitHub	2023-05-11 15:25:54
