* Updating Changelog to reflect what's changing in 1.22.1
* Bug fix: Setting the same constraint multiple times is no longer allowed.
* Constraints map has been added to handle constraints being added to Aurora Jobs.
* Lowering timeout to avoid flaky test for bad payload timeout.
* Adding attributes to Mesos agents in order to test limits by constraint.
* Make two instances schedulable per zone in order to experience flaky behavior.
* Updating thrift definitions to add autopause for batch based update strategies.
* Adding batch calculator utility and test cases for it.
* Adding PauseUpdateMonitor which allows users to poll Aurora for information on an active Update being carried out until it enters the ROLL_FORWARD_PAUSED state.
* Tests for PauseUpdateMonitor and VariableBatchStep added to the end to end tests.
* Adding TerminalUpdateStates function which returns a slice containing all terminal states for an update. Changed signature of JobUpdateStatus from using a map for desired states to a slice. A map is no longer necessary with the new version of thrift and only adds complexity.
* Changing generateBinding.sh check to check for thrift 0.12.0 and adding support for Variable Batch updates.
* Adding update strategies change to changelog, changed docker-compose to point to aurora 0.22.0 snapshot. Added test coverage for update strategies.
* Bumped up version to 1.21.1
* Moving admin functions to a new file. They are still part of the same pointer receiver type.
* Removing dead code and fixing some comments to add space between backslash and comment.
* Adding set up and tear down to run tests script. It sets up a pod, runs all tests, and then tears down the pod.
* Added `--rm` to run tests Mac script.
* Removing cookie jar from transport layer as it's not needed.
* Changing all error messages to start with a lower case letter. Changing some messages around to be more descriptive.
* Adding an argument to allow the retry mechanism to stop if a timeout has been encountered. This is useful for mutating API calls. Only StartUpdate and CreateService have enabled by default stop at timeout.
* Added 2 tests for when a call goes through despite the client timing out. One is with a good payload, one is with a bad payload.
* Updating changelog with information about the error type returned.
* Adding test for duplicate metadata.
* Refactored JobUpdateStatus monitor to use a new monitor called JobUpdateQuery. Update monitor will now still continue if it does not find an update to monitor. Furthermore, it has been optimized to reduce returning payloads from the scheduler as much as possible. This is through using the GetJobUpdateSummaries API instead of JobUpdateDetails and by including a the statuses we're searching for as part of the query.
* Added documentation as to how to handle a timeout on an API request.
* Optimized GetInstancesIds to create a copy of the JobKey being passed down in order to avoid unexpected behavior. Instead of setting every variable name separately, now a JobKey array is being created.
* Ported all code from Thrift 0.9.3 to Thrift 0.12.0 while backporting some fixes from gorealis v2
* Removing git.apache.org dependency from Vendor folder as this dependency has migrated to github.
* Adding github.com thrift dependency back but now it points to github.com
* Removing unnecessary files from Thrift Vendor folder and adding them to .gitignore.
* Updating dep dependencies to include Thrift 0.12.0 from github.com
* Adding changelog.
* End to end tests: Adding coverage for killinstances.
* End to end tests: Deleting instances after partition policy recovers them.
* End to end tests: Adding more coverage to the realis API.
* End to end tests: Allowing arguments to be passed to runTestMac so that '-run <test name>' can be passed in.
* End to end tests: Reducing the resources used by CreateJob test.
* End to end tests: Adding coverage for Pause and Resume update.
* End to end tests: Removed checks for Aurora_OK response as that should always be handled by the error returned by the API. Changed names to be less verbose and repetitive.
* End to end tests: Reducing watch time for instance running when creating service for reducing time it takes to run end to end test.
