AWS API Changes

2023/04/28 - AWS SimSpace Weaver - 1 new 3 updated api methods

Changes Added a new CreateSnapshot API. For the StartSimulation API, SchemaS3Location is now optional, added a new SnapshotS3Location parameter. For the DescribeSimulation API, added SNAPSHOT_IN_PROGRESS simulation state, deprecated SchemaError, added new fields: StartError and SnapshotS3Location.

CreateSnapshot (new)

Link ¶

Creates a snapshot of the specified simulation. A snapshot is a file that contains simulation state data at a specific time. The state data saved in a snapshot includes entity data from the State Fabric, the simulation configuration specified in the schema, and the clock tick number. You can use the snapshot to initialize a new simulation. For more information about snapshots, see Snapshots in the SimSpace Weaver User Guide .

You specify a Destination when you create a snapshot. The Destination is the name of an Amazon S3 bucket and an optional ObjectKeyPrefix . The ObjectKeyPrefix is usually the name of a folder in the bucket. SimSpace Weaver creates a snapshot folder inside the Destination and places the snapshot file there.

The snapshot file is an Amazon S3 object. It has an object key with the form: object-key-prefix/snapshot/simulation-name-YYMMdd-HHmm-ss.zip , where:

YY is the 2-digit year
MM is the 2-digit month
dd is the 2-digit day of the month
HH is the 2-digit hour (24-hour clock)
mm is the 2-digit minutes
ss is the 2-digit seconds
