⚠ BREAKING CHANGES

• glue-alpha: Glue job constructs now reject construct-managed and Glue-reserved
  arguments passed through defaultArguments. Previously, a managed argument set via
  defaultArguments was silently honored in SparkJob and PythonShellJob (customer
  value won over the construct default) and silently ignored in RayJob (construct
  default won). Both behaviors let a caller bypass the construct's security and
  observability defaults with no error. Passing any of the following through
  defaultArguments now throws a ValidationError at synthesis time:
• construct-managed arguments — --enable-continuous-cloudwatch-log,
  --continuous-log-logGroup, --continuous-log-logStreamPrefix,
  --continuous-log-conversionPattern, --enable-continuous-log-filter,
  --enable-metrics, --enable-observability-metrics, --enable-spark-ui,
  --spark-event-logs-path, --job-language, --class, --extra-jars,
  --user-jars-first, --extra-py-files, --extra-files, library-set
• Glue-reserved arguments — --debug, --mode, --JOB_NAME, --endpoint

A managed argument is rejected whether or not the current configuration emits it, so a
disabled feature (e.g. enableMetrics: false) cannot be re-enabled through
defaultArguments. Configure these through their dedicated props instead
(continuousLogging, enableMetrics, enableObservabilityMetrics, sparkUI,
className, extraJars, extraJarsFirst, extraPythonFiles, extraFiles). For
example, replace defaultArguments: { '--enable-continuous-cloudwatch-log': 'false' }
with continuousLogging: { enabled: false }. Arguments without a dedicated prop (e.g.
--enable-glue-datacatalog) are unaffected and remain settable via defaultArguments.

The checkNoReservedArgs(defaultArguments?) method on the Job base class was removed.
It is replaced by two protected members: setManagedArgument(key, value?), which each
job class calls to declare (and, when a value is present, emit) a managed argument, and
mergeDefaultArguments(defaultArguments?), which validates the caller-supplied
defaultArguments against the accumulated reserved set and returns the merged map.

• route53resolver-alpha: FirewallRuleGroupAssociation now honors the previously-ignored mutationProtection and name props. Stacks that set mutationProtection: true will enable mutation protection on redeploy (which blocks further CloudFormation update/delete until it is set back to false); stacks that set name will write it to the template, which may replace the association.
• glue-alpha: trigger Action and Condition are no longer plain objects — use Action.job(...) / Action.crawler(...) and Condition.job(...) / Condition.crawler(...). Jobs are referenced via IJobRef and crawlers via ICrawlerRef (a CfnCrawler instance or CfnCrawler.fromCrawlerName(...)) instead of a CfnCrawler field or crawler-name string; IJob now extends the generated IJobRef. addDailyScheduledTrigger/addWeeklyScheduledTrigger/addCustomScheduledTrigger are replaced by addScheduledTrigger(id, { schedule, ... }) (use TriggerSchedule.daily()/weekly()/cron(...)). addNotifyEventTrigger is renamed addEventTrigger (NotifyEventTriggerOptions → EventTriggerOptions). All addXxxTrigger methods now return ITriggerRef instead of CfnTrigger.
• glue-alpha: PartitionProjectionConfiguration's variant fields (integerRange, dateRange, interval, digits, format, intervalUnit, values) are no longer public; DATE projection now takes step: { interval, intervalUnit } instead of top-level interval/intervalUnit.
• glue-alpha: ConnectionOptions no longer has subnet, vpc, or vpcSubnets; use network: ConnectionNetwork.subnet(...) or network: ConnectionNetwork.vpc(...) instead.

Features

• glue-alpha: ensure job parameters consistency (#38480) (bc7dc0c)

• glue-alpha: model partition projection variants as internal state (#38726) (16527cd)

⚠ BREAKING CHANGES

L1 resources are automatically generated from public CloudFormation Resource Schemas. They are built to closely reflect the real state of CloudFormation.

Alpha modules (2.268.0-alpha.0)

⚠ BREAKING CHANGES

• glue-alpha: DataQualityTargetTable's constructor is removed — use DataQualityTargetTable.fromTable(database, table) or fromTableName(database, tableName); IDatabase now extends IDatabaseRef.
• glue-alpha: DataQualityRulesetProps.clientToken is removed; use the CfnDataQualityRuleset L1 for request-level idempotency.
• glue-alpha: S3Table.clientSideEncryptionKey is now kms.IKeyRef instead of kms.IKey.
• glue-alpha: DataQualityRulesetProps.rulesetName is now required. AWS::Glue::DataQualityRuleset made Name a required property, so the name can no longer be left for CloudFormation to generate.

Features

• glue-alpha: reference-typed DataQualityTargetTable and remove clientToken (#38730) (c8fafbd)

Code Refactoring

• glue-alpha: use kms.IKeyRef for KMS key inputs where possible (#38725) (604ac23)

⚠ BREAKING CHANGES

• kinesisfirehose: After this change, specifying an unsupported timeZone on the Firehose S3Bucket destination now throws a ValidationError during synthesis instead of failing at CloudFormation deployment. Affected values: 3-letter IANA abbreviations (e.g. EST), Etc/UTC, Etc/GMT, Factory, and strings containing characters outside [a-zA-Z/_]+. Use a supported standard IANA identifier (e.g. America/New_York) or UTC for synth to pass.

• stack.availabilityZones are not stable strings (#38580) (f89474a)

Alpha modules (2.267.0-alpha.0)

⚠ BREAKING CHANGES

• glue-alpha: schema Type is now an opaque class; construct column types via the Schema factories or Schema.custom(...) rather than { isPrimitive, inputString } literals. StorageParameter.custom(key, value) requires a string value, and StorageParameter.writeKmsKeyId takes a kms.IKey instead of a string.
• glue-alpha: S3TableProps.bucket/encryption/encryptionKey are removed. Use storage: S3TableStorage.managedBucket(S3TableEncryption.kms(key?)) / S3TableStorage.fromBucket(bucket) and clientSideEncryption: TableClientSideEncryption.kms(key?). S3Table.encryption/encryptionKey are removed (clientSideEncryptionKey exposes the client-side key; read bucket.encryptionKey for server-side). The TableEncryption enum and the deprecated Table/TableProps are removed — use S3Table.

Features

• glue-alpha: add a typed secret input to Connection (#38585) (ede4a1c)
• glue-alpha: add subnet selection to Connection (#38561) (f9d7eac)
• glue-alpha: model S3Table storage/encryption as value objects (#38591) (9990e16)

Alpha modules (2.266.0-alpha.0)

⚠ BREAKING CHANGES

• glue-alpha: DataQualityRulesetProps.rulesetDqdl: string is replaced by
  dqdl: Dqdl. Build it with Dqdl.fromString('Rules = [ ... ]').
• glue-alpha: s3Encryption, cloudWatchEncryption, and jobBookmarksEncryption are no longer object literals. Use S3Encryption.s3Managed() / S3Encryption.kms(key?), CloudWatchEncryption.kms(key?), and JobBookmarksEncryption.clientSideKms(key?). The CloudWatchEncryptionMode and JobBookmarksEncryptionMode enums are removed (their mode is now implicit); S3EncryptionMode is retained.
• glue-alpha: this is a corrective breaking change. Apps that leaned on the bug, and did things like InputFormat x = OutputFormat.AVRO; will get a compilation error in other jsii languages. The intended usage, on the other hand, was broken before and works now.
• glue-alpha: workerType and numberOfWorkers are no longer top-level job props. For Spark jobs, pass them together via workerConfiguration: { workerType, numberOfWorkers }. PythonShellJob no longer accepts them (it is sized by maxCapacity). RayJob no longer accepts workerType (it is fixed to Z.2X).
• glue-alpha: SparkJobProps.enableMetrics removed, which will cause a compilation error for any app using it. But there is no behavior change, since this is a dead prop.
• glue-alpha: a differing/tokenized has_encrypted_data supplied via parameters now throws.

• aws-cloudwatch: AWS::CloudWatch::LogAlarm: QueryLanguage property has been removed from the ScheduledQueryConfiguration type.
• aws-elasticloadbalancing: AWS::ElasticLoadBalancing::LoadBalancer: Id attribute has been removed and the primary identifier is now LoadBalancerName.
