Main achievements
In addition to ongoing general maintenance and support of cardano environments, some highlights of SRE achievements for this quarter include:
All IOE cardano-parts supported node environments, including preview, preprod, and mainnet were upgraded through cardano-node releases including
10.3.1and10.4.1with various additional pre-release versions tested.The cardano performance cluster used for benchmarking was upgraded to ephemeral instance configuration to additionally benchmark LMDB ledger backend.
Peer snapshot files (and checkpoint file for mainnet) are now a regular part of the release binary artifacts in preparation for genesis mode.
Genesis mode has been rolled out as the default consensus mode for preview and preprod testnets.
Adawallet and Cardano-airgap repos received significant updates to prepare for some complex but infrequent pool operations.
Aarch64-linux resources were brought online in the Hydra build cluster.
Details for this and many other SRE work items can be found in the biweekly SRE reports.
