- The ledgers are stored in a sqlite database in ledger file system.
- Ledgers are organized in shards inside primary folder.
- Raw inputs are saved as shards inside blob folder. No input files are created if neither inputs nor outputs are available.
- Both last primary shard hash and last blob shard hashes are subjected to consensus and necessary sync operations are performed if out of sync.
- Hpfs sync support setting single sync targets from both ends of the list. (Targets set from front are prioritized).
- Contract and ledger syncs and serving are performed independently.
- Creating two separate hpfs folders for contract and ledger file systems (contract_fs and ledger_fs).
- Added separate mounts for contract and ledger file systems.
- Added separate instances for contract serving and ledger serving.
- Added separate instances for contract syncing and ledger syncing.
- Modified cluster creating script to accompany folder name changes in contract folder.
* Refactoring hpfs code to a class so it can support multiple mounts.
* Refactoring hpfs serve into a class to support mulitiple mount serving.
* Refactoring hpfs sync into class to support multiple instances.
* Code improvements in hpfs_sync.
* Taking a sync target list for hpfs syncing target set.
