OSIS
Object Storage and Indexing System A system for storing root objects efficiently and indexed by certain fields.
OSIS comprises of 2 elements:
- Indexer: responsible for indexing and identifying objects
- Storer: responsible of storing in different databases, with varying encodings, and encryption.
Indexer
The indexers primary duty is to be able to create and query sql tables for a given base object specification and it's indices. For instance: I specify a Base Object called Pet, and I specify Pet so that (more on writing specifications here) it's breed tag is indexable.
struct Pet {
breed string @[index]
}
Given this specification, the indexer is expected to create an sql table with the breed field as a column. This allows the backend to filter and search base objects by their fields. Note that, the object isn't stored on the table, but just it's id. Object storage and modification is handled by the
Getting started
Generic Code
The solution provided by this module is to create a backend interface with generic CRUD + list + filter methods for root objects that different backends can implement.
This allows for a single generated actor code to use different backends, without having to generate separate code for each. Having less generated code is less prone to errors, and using the same backend methods for each actor makes it easier modify, fix and add features to the backends. Using the same data manipulation methods in generated code also makes it easier to generate code for the actor as the implementations don't differ for different root objects.
