Implement backend logic to suggest valid cycle/pass/scene to end user and validate the cycle/pass/scene inputs

[viviant100]

Build a microservice that receives the CNM messages from IA and perform analysis on the CNM messages in order to provide valid cycle/pass/scene for the users (3sp)

• Attach a new SQS queue to I&A SNS topic for the CNM messages.

Pre-verification for client-side to validate the input (2sp),

The suggestion feature does not seem reasonable to implement as currently proposed. The current state of this feature proposes that:

• when nothing is provided, a list of valid cycles is returned
• when a cycle is provided, a list of valid passes is returned
• when a cycle + pass is provided, a list of valid scenes is returned

For context: each variable in the search is dependent on the variable before it. If a list of valid passes and scenes is generated from a cycle, the combination of both the pass + scene as a pair must be utilized together to form a valid CPS combo.

The SWOT satellite is expected to generate a lot of PIXC/PIXCVec tiles which are used to generate scenes when combined together. As a result, valid combinations generated could potentially reach the hundreds/thousands on each variable. In order to support this functionality, we would need to build out a process within ingest-to-sds which generates search indices for each of these parameters for the API to utilize.

For example:

• an index entry of (null,null,null) -> [list of valid cycles]
• an index entry of (123,null,null) -> [list of valid passes]
• an index entry of (123,123,null) -> [list of valid scenes]
• an index entry of (123,123,123) -> [(123,123,123)] (Just as a way to verify this entry is valid)

Each of these indices would need to be updated as a granule is ingested through the SDS. Performing this work would be fairly non-trivial for a feature that doesn't seem like it would be useful once Earthdata Search integration is implemented.
