Frequency User Data
On Frequency, User Data and select Announcements are mapped to Schemas which use Stateful Storage for storage and retrieval of the data.
User Data Sets
| User Data Set | Deployed Schema Ids | Frequency Model Type | Frequency Payload Location | Settings |
|---|---|---|---|---|
| Public Follows | Mainnet: 8 Testnet (Paseo): 8 Testnet (Rococo): 13 | AvroBinary | Paginated | None |
| Private Follows | Mainnet: 9 Testnet (Paseo): 9 Testnet (Rococo): 14 | AvroBinary | Paginated | None |
| Private Connections | Mainnet: 10 Testnet (Paseo): 10 Testnet (Rococo): 15 | AvroBinary | Paginated | None |
Pseudonymous Relationship Identifiers (PRIds) are stored along side Private Connections in the same Stateful Storage page.
Source code for each schema is located in the LibertyDSNP/schemas repository.
Announcements
| Announcement | Deployed Schema Ids | Frequency Model Type | Frequency Payload Location | Settings |
|---|---|---|---|---|
| Public Key | Mainnet: 7 Testnet (Paseo): 7 Testnet (Rococo): 7 | AvroBinary | Itemized | Append Only, Signature Required |
Read Operation Mapping
Stateful data is retrieved via state queries (pallet.stateQuery) or RPC calls (pallet.rpcCall()).
| Model Type | DSNP Properties | Query/Call |
|---|---|---|
| Itemized | Entity Tag | stateful_storage.getItemizedStorage() |
| Paginated | Entity Tag, Chunked | stateful_storage.getPaginatedStorage() |
Write Operation Mapping
Write operations are via Transactions (also called Extrinsics): pallet::extrinsic()
| Model Type | Operation | Pallet::Extrinsic |
|---|---|---|
| Itemized | Insert, Update, Delete | stateful_storage::apply_item_actions()stateful_storage::apply_item_actions_with_signature() |
| Paginated | Insert, Update | stateful_storage::upsert_page()stateful_storage::upsert_page_with_signature() |
| Paginated | Delete | stateful_storage::delete_page()stateful_storage::delete_page_with_signature() |
Entity Tags
Frequency requires the hash of current state for any Stateful Storage change.
