Is there an api (like hibernate, etc) to manage temporal data in Google Cloud Datastore? Basically i need to maintain bi-temporal data in my datastore. Is there an api that i can use to easily manage this?
I'm not 100% sure what you mean by "bi-temporal data".
If you mean different data classes that are have different pricing and access times, there are different storage classes (standard and nearline). https://cloud.google.com/storage/docs/storage-classes . These are set at the bucket level at creation time. For example: gsutil mb -c nearline -l region bucket-url
.
You can also set a time-to-live at the bucket level. https://cloud.google.com/storage/docs/lifecycle
Using gsutil
you can set this policy by uploading a JSON file like this example from the docs:
{
"lifecycle": {
"rule":
[
{
"action": {"type": "Delete"},
"condition": {"age": 365}
}
]
}
}
Save to a file and then gsutil set json-file-name bucket-url
.
