Cardano DB Sync 13.8.0.0 Add Node 11.2 Support and ARM Linux Builds

Cardano DB Sync 13.8.0.0 don launch for Cardano networks, dey use node 11.2.0 and bring changes for configuration, logging and database maintenance.

DB Sync dey follow the Cardano blockchain and dey store information from the chain and ledger inside PostgreSQL database. Explorers, analytics platforms and other applications fit query that database to access network data.

Cardano DB Sync Change Logging and Add ARM Support

The new release dey read the nested configuration format wey node 11.2.0 introduce and e don move logging go the node trace-dispatcher system.

This change mean say operators need update their logging configuration. Settings wey iohk-monitoring bin dey use before, including minSeverity and setupScribes, no go dey read again. The release notes direct operators to replace those settings with TraceOptions block using the mainnet configuration as example.

Version 13.8.0.0 still introduce static binaries and Docker images for 64-bit ARM Linux systems. Static binaries still dey available for 64-bit x86 Linux.

New --ledger-only option dey replay the blockchain through the ledger and dey write ledger snapshots without opening the database. Operators fit use am to prepare up-to-date ledger snapshot before upgrade.

Database Migrations and Data Fixes

Operators wey dey upgrade from DB Sync 13.7.2.1 go run three quick database migrations when the new version start, according to the release notes.

The migrations add guard to the list of script purpose types, remove duplicate epoch state records and introduce uniqueness constraint on the epoch number. Dem still repair collateral parameters for two database tables wey bin dey affected by signed 16-bit encoding issue.

No full resynchronization dey required when you dey upgrade from any 13.7.x version. Older installations go run additional migrations: upgrades from 13.7.1.x include the epoch redesign migrations wey dem introduce for 13.7.2.1, while upgrades from 13.7.0.x go still run one earlier epoch repair.

The release notes talk say the redesign migrations fit take several minutes on mainnet. The earlier repair fit add five to 15 minutes for mainnet-sized database.

DijkstraNet Testing and DB Sync Upgrade Notes

The release land as Cardano infrastructure teams dey prepare their tools for Dijkstra. On November 2, the DijkstraNet test network move to protocol version 12 without activating Linear Leios, give developers and operators environment for integration testing.

DB Sync 13.8.0.0 dey use node 11.2.0, but the release notes still point operational details for teams wey dey maintain existing services. The epoch view dey calculate the current epoch dynamically, and queries against am fit slow by around 500 milliseconds on mainnet. Applications wey no need the current epoch fit query epoch_finalized directly.

The release notes list one known issue: IPv4 and IPv6 addresses for stake pool relays fit store with literal double quotes. Dem still list links to mainnet snapshots for versions 13.7 and 13.6, while the entry for 13.8 snapshot still mark as pending.
