* [Self-service error codes] Enabled by default * Flag changed to `use-pre-1.18-error-codes` (disabled by default) CHANGELOG_BEGIN [Ledger API Specification] The Ledger API returns enriched error codes (see https://docs.daml.com/error-codes/self-service/index.html) For backwards-compatibility, a new API flag `--use-pre-1.18-error-codes` is introduced for preserving the legacy behavior for clients that want to migrate incrementally to the changed gRPC status code responses and error details format.

Overview
This document is to help internal engineers work with ledger-on-memory.
ledger-on-memory is a key/value-based ledger that uses a simple in-memory map as an
underlying storage. It uses either H2 or PostgreSQL as its index database.
Ledger On Memory
To build a fat JAR with the server built from HEAD run
bazel build //ledger/ledger-on-memory:app_deploy.jar
The application can be run from command line with the following command:
java -Xmx4G -XX:+UseG1GC -jar bazel-bin/ledger/ledger-on-memory/app_deploy.jar --participant participant-id=foo,port=6861
As run from the main project root directory (adjust the location of the JAR according to your working directory).
Alternatively, the application can be run using the Bazel command:
bazel run //ledger/ledger-on-memory:app -- --participant participant-id=foo,port=6861
Creating ledger exports
Ledger On Memory can be used to generate ledger exports through an environment variable:
export KVUTILS_LEDGER_EXPORT=/path/to/export/file
Then launch the ledger using the Bazel or Java command as described above.
