v0.7.5

This tiny release adds support for Scala Native and optimizes the performance of datasource-backed queries

What's Changed

• Optimize execution of datasource-backed ZQueries by @kyri-petrou in #501
• Update README.md by @zio-assistant in #502
• Scala Native support by @kyri-petrou in #503
• Add Scala Native to project aggregates by @kyri-petrou in #504
• Update ZIO and enable multi-threading for Scala Native by @kyri-petrou in #505
• Use separate CI job to check website build by @kyri-petrou in #506
• Optimize init and restoration of FiberRefs when running queries by @kyri-petrou in #507

Full Changelog: v0.7.4...v0.7.5

v0.7.4

This minor release contains performance improvements for short-lived queries, but more importantly, queries that heavily utilize ZQuery.fromRequest. It is also fully binary compatible with the v0.7.x series.

What's Changed

• Improve performance of ZQuery#run by @kyri-petrou in #497
• Update README.md by @zio-assistant in #498
• Use a single FiberRef for retrieving the Cache and identifying disabled caching by @kyri-petrou in #495
• Make ZQuery#run reentrant safe by @kyri-petrou in #499

Full Changelog: v0.7.3...v0.7.4

v0.7.3

This very minor release contains performance optimizations for queries that rely heavily on deduplication of requests.

And it is fully binary and source compatible with the v0.7.x series!

Highlights

• Avoid unnecessary creation of Both / Then when BlockedRequests == Empty by @kyri-petrou in #494

Other changes

• Update CI and plugin versions by @kyri-petrou in #492
• Update README.md by @zio-assistant in #493

Full Changelog: v0.7.2...v0.7.3

v0.7.2

This minor release adds new eager ZQuery.*Now constructors (e.g., ZQuery.succeedNow) that allow users to lift pure values into a ZQuery. Eagerly constructed queries allow for more aggressive under-the-hood optimizations at the cost of not capturing side-effects. As such, they should only ever be used for lifting pure values, and never in recursive methods!

Highlights

• Allow queries to be eagerly constructed by @kyri-petrou in #488

Other changes

• Bump zio & other deps by @kyri-petrou in #484
• Update README.md by @zio-assistant in #485
• Update zio to 2.1.1 by @kyri-petrou in #486
• Update ZIO version by @kyri-petrou in #487
• Make methods on ZQuery non-final by @kyri-petrou in #489
• Remove unused type param from Cache#lookup by @kyri-petrou in #490

Full Changelog: v0.7.1...v0.7.2

v0.7.1

This release brings some new constructors and methods that extend ZQuery's functionality as well as some minor performance improvements.

Highlights

• New query constructors and method aliases by @kyri-petrou in #480
• Add method to memoize the result of a ZQuery by @kyri-petrou in #481

Other changes

• Re-enable MiMa and set versionScheme to early-semver by @kyri-petrou in #477
• Update README.md by @zio-assistant in #478
• Update benchmarking results for v0.7.0 by @kyri-petrou in #479
• Avoid unnecessary flatmaps in various methods by @kyri-petrou in #482
• Update sbt to 1.10 by @kyri-petrou in #483

Full Changelog: v0.7.0...v0.7.1

v0.7.0

Release Notes

This release focuses heavily on improving the performance of query execution for DataSource-backed queries. Applications that heavily rely on ZQuery.fromRequest for batching a large number of requests should see a notable improvement in performance. In v0.6.x, batching of ~1,000 unique requests to a single datasource would take approximately 1ms of CPU time according to our benchmarks. With this new release, batching of the same number of requests takes ~200-250us (~x4-5 improvement) 🚀

New additions

• Added multiple new constructor methods for CompletedRequestMaps. If your code relies on creating custom DataSources, make sure to check them out! (see section below for more info)
• Added an overload to Cache.empty that allows pre-sizing the underlying cache. This can improve performance in cases where there are a large number of requests

Deprecations

In order to improve performance as much as possible, the internals of Cache and CompletedRequestMap were re-written to utilize mutable data structures, which offer much better performance than immutable ones. In order to avoid mutability leaking into existing user's code, the ++, insert and insertOption on CompletedRequestMap remain immutable but have been deprecated as they'll lead to sub-optimal performance.

Users that construct DataSource and CompletedRequestMap manually, should migrate their existing code to use one of the many new constructors added in the CompletedRequestMap companion object instead. See below for some migration examples:

Single request:

val request = ???

// v0.6.x
CompletedRequestMap.empty.insert(request, Exit.succeed(value))

// v0.7.0
CompletedRequestMap.single(request, Exit.succeed(value))

Iterable of (request, value):

case class GetId(id: UUID) extends Request[Nothing, GetId]
case class Response(value: String)
val keysAndValues: List[(UUID, String)] = ???

// v0.6.x
keysAndValues.foldLeft(CompletedRequestMap.empty) { case (map, (k, v)) => map.insert(GetId(k), Response(v)) }

// v0.7.0
CompletedRequestMap.fromIterableWith(keysAndValues)(kv => GetId(kv._1), kv => Response(kv._2))

v0.6.1

Release Notes

This release brings a new set of constructors for CompletedRequestMap, which allow create one from iterables. It also includes an important bug fix that caused significant performance degradation of queries composed of parallel and sequential datasource-based queries. It is fully backwards compatible with v0.6.0

New additions

• Implement Some Additional Completed Request Map Constructors by @adamgfraser in #460
• Add fromZIONow variant of fromZIO by @kyri-petrou in #465

Performance improvements and fixes

• Fix issue with parallel queries being executed multiple times if zip is used by @kyri-petrou in #464
• Avoid filtering requests when CompletedRequestsMap is empty by @kyri-petrou in #466

Other changes

• Update README.md by @zio-assistant in #461
• Add benchmark to compare performance with Fetch by @kyri-petrou in #463
• Check binary compatibility using MiMa & update dependencies by @kyri-petrou in #462

New Contributors

• @kyri-petrou made their first contribution in #463

Full Changelog: v0.6.0...v0.6.1

v0.6.0

This release changes the signature of Request to be invariant. This increases the type safety of queries but may mean the compiler is stricter in enforcing that in some cases. In connection with this, the signature of CompletedRequestMap#insert has been updated to not be curried for improved type inference. If you are using higher level constructors to define your data sources this change should not impact you.
