This is essentially a rerelease of 4.0.0, so full release notes included here for simplicity:
βοΈ Breaking changes
- Removes a number of static objects, in particular the "default" Atlan client that was accessible through
Atlan.getDefaultClient()
by @cmgrote in #1072. Every operation that interacts with Atlan (ultimately sending it an API request) must now be explicitly passed anAtlanClient
. This change was made for two primary reasons:- It makes explicit which operations will interact with Atlan (those that require an
AtlanClient
to be passed) vs those that only operate on information locally in-memory (those that do not require anAtlanClient
to be passed). - It removes concurrency limitations and risks with shared static resources across the entire JVM (including all threads therein). This applies not only to the default client but also to some of the caches that were being automatically managed.
- It makes explicit which operations will interact with Atlan (those that require an
- Packages developed using this release of the package toolkit will now need to make use of a broader
PackageContext
object that similarly encapsulates the client and any extra caches specific to packages.

AtlanClient changes
As mentioned in the breaking changes, this release introduces a complete revamp of the way the AtlanClient
is managed and passed around to operations that actually call Atlan APIs behind-the-scenes.
Resource-isolated
Previously the client itself and some caches were managed statically across the entire JVM. This could cause non-obvious and very difficult reproduce issues when heavy concurrency exists. With this release, all caches are managed within the AtlanClient
directly, and there is no longer a JVM-wide static client. Instead, you can create a new client and have it "live" only for as long as you need it:
try (AtlanClient client = new AtlanClient()) {
// Do anything you need against Atlan within this block
}
// Once you exit the block, the client and all its internal caches will be removed
Must be explicitly passed
Furthermore, any operation that actually interacts with Atlan directly (ultimately via its APIs behind-the-scenes) must now be explicitly passed such a client:
GlossaryTerm term = GlossaryTerm.findByName(client, "A", "B");
term.trimToRequired().userDescription("Hi there!").build().save(client);
This means there is an extensive set of changes to many of the methods across the SDK β if you're planning to adopt this release (and higher), rather than reading a huge list of such operations it'll probably be simplest to update your dependency to this latest release in your codebase and then look for any compilation breakages. The explicit AtlanClient
is almost always expected as the new first parameter in any methods that now require it.
Package toolkit
Introduction of PackageContext
In the same way we have resource-isolated the client and its caches for the SDK, we have resource-isolated the context of a running package and its further caches in this release. The full context needed for running a package is now bundled into an object called a PackageContext
, which can be created from a package's configuration using Utils.initializeContext()
and passing it te configuration. Where you previously may have just used this pattern:
@JvmStatic
fun main(args: Array<String>) {
val config = Utils.setPackageOps<OpenAPISpecLoaderCfg>()
// Receive inputs from the config to decide what to do in your logic
}
You should now use this pattern:
@JvmStatic
fun main(args: Array<String>) {
Utils.initializeContext<OpenAPISpecLoaderCfg>().use { ctx ->
// Receive inputs from the config to decide what to do in your logic
val url = ctx.config.specUrl // config items will be available nested under ctx.config
val client = ctx.client // the AtlanClient will be nested under ctx.client
val termCache = ctx.termCache // a number of lazy-load-managed caches are also available in the context
}

βοΈ Breaking changes
- Previously, there were at least 2-3 separate approaches used for caching across the SDK and custom package toolkits, despite all of them relying purely on on-heap memory. In this release caches have been revamped:
- to be more consistent (same operations across caches)
- to move them off-heap (with disk spilling)
- We have tried to minimize the impact of this change, but if you are using these caches directly (or related custom package runtime toolkit functionality) you may be impacted. See the end of the release notes for further details.
- The custom package testing toolkit's interface has also been changed slightly:
- The
PackageTest
class now requires a "tag" parameter, that is used in all generated names for that test to make them more immediately identifiable. - Rather than calling the
setup()
method with your custom package's configuration and then directly invoking your custom package's code (typically via itsmain()
method), you should now use therunCustomPackage()
method β which takes both the configuration and your custom package's execution method as parameters. This ensures your custom package is executed with appropriate isolation from any others that may be tested in parallel.

Caching changes
As mentioned in the breaking changes, this release introduces a complete revamp of the way caching is done across both the SDK and custom package toolkits.
Moved off-heap
Previously the caching was done entirely in-memory, on-heap. This naturally limited its scale β to the point where we had begun to observe OutOfMemory
errors in some cases. With this release, all caches are moved off-heap and managed by an embedded, persistent key-value store that still offers high performance. (Note that this does mean some temporary files will be created locally to manage the caches β these are created using Files.createTempDirectory()
, so the specific location will depend on how the JVM manages this on your system.)
Consistency changes
We've consolidated 2-3 different interfaces for caching that had evolved independently during the lifecycle of the SDK and package toolkit to date, resolving that tech debt so that all can directly benefit from the move to off-heap.
- Each cache now manages the following for each object in it:
- an ID (always a UUID)
- a human-readable name
- an optional secondary ID (such as the hashed-string internal representation for tags and custom metadata)
- the actual object that was cached
- Retrieval now uses these options almost exclusively, for consistency. For example, instead of
.getCustomMetadataDef()
on the custom metadata cache, you would now just use.getByName()
. - Prior operations like
lookupAssetByIdentity
andlookupAssetByGuid
in some cache variations have been made consistent, tolookupByIdentity
andlookupById
. - Wherever possible the caches are now implemented using Java generics typing, so should return strong types without needing casting (rather than generic types like
Asset
).
Necessary interface changes
Various places that used to make use of collections (Collection<Asset>
, List<Asset>
, etc) now instead either directly make use of the new OffHeapAssetCache
or of Stream<Asset>
β to no longer require everything in-memory on the heap in order to be able to process it. All caches are now generally Closeable
, too, to allow them to self-manage cleaning up any temporary files they use for persistence.
Utils.updateConnectionCache()
in the custom package runtime toolkit (now usesOffHeapAssetCache
)PersistentConnectionCache.deleteAssets()
and.addAssets()
in the custom package runtime toolkit (now processStream<Asset>
)AssetGenerator.cacheCreated()
interface (now processesStream<Asset>
)ImportResults.Details
internal tracking of created, updated, restored and skipped assets (now useOffHeapAssetCache
)AssetRemover.deleteAssets()
in the custom package runtime toolkit (now usesOffHeapAssetCache
)DeltaProcessor.run()
in the custom package runtime toolkit (now usesOffHeapAssetCache
)AtlanClient
itself is nowCloseable
, so it can clean up its own managed cachesAssetBatch
andParallelBatch
no longer offer fluent-builder creation, but only overloaded constructors, and both now track their processing of created, updated, restored and skipped assets inOffHeapAssetCache
s, and are nowCloseable
so they can clean up their own managed caches.
