# Storage Requirements Meeting - 2020-08-20

## Participants

- Thibault Martinez
- Louay Kamel
- Bing-Yang Lin
- Christian Poveda
- Samuel Rufinatscha

## Discussion topics

- Keep RocksDB for the start
- MyRocks in the future; safe DB
- Already possible to store transactions; however not indexed;
- Higher layers should specify what should be indexed or not (not the storage crate);
- Top priorities for schema:
    - Transaction
    - Milestone
    - TransactionMetadata
    - LedgerDelta
- Transaction is stored as byte array, accessable by the transaction hash
- With the second part of Chrysalis, lots of datastructures do change; maybe not worth to focus on addresses, bundles etc.;
- Testing storage with tests of previous version;
- Only implementation of LedgerDelta is missing at the moment, besides that all datastructures are implemented in Bee and can be utilized by storage;
-
