High level summary
- Updated the centralized chain-sync-jumping model to allow using it as a substitute for the real model, which will make it easier to troubleshot potential test failures found in our property tests (#1466).
- Engaged with Cardano Foundation on the Antithesis workstream, which will help us widen the test coverage and robustness of the Cardano node.
- Enriched
db-immutaliser to inspect a VolatileDB (1482). - Released Node 10.4.1, which incorporates the UTXO-HD feature. The default backend will be the in memory one. The LMDB backed is not recommended for block producers, but we encourage users to experiment with it and report their experience.
- Our benchmarks show no significant performance degradation, rating it production ready.
- A small 2% / 5% (169MiB / 389MiB) increase in heap size could be expected.
- However, this is mitigated by the fact that going from 10.2 to 10.3, we saw a significant reduction in heap size - namely 6% / 14% (579MiB / 1267MiB).
- 10.4 reduces CPU usage slightly again
- There is no impact on network performance.
