# Ledger on SQL

This is an implementation of a ledger using _kvutils_ on top of an SQL database. Currently, it can
be run on top of H2, PostgreSQL, or SQLite.

The code under _src/main_ implements the logic, using _kvutils_. This code is production-ready and
used by _Sandbox_.

The code under _src/app_ is a trivial application front-end to the ledger that spins it up, along
with a Ledger API Server. This is _not_ intended to be used in production, and is currently only
used in testing.
ledger-on-sql: Use random log entry ID allocation so we don't depend on `SeedService`. [KVL-1002] (#10255) * ledger-on-sql: Abstract out the log entry ID allocator. This is so we don't need to depend on `SeedService`. CHANGELOG_BEGIN CHANGELOG_END * kvutils: Remove `allocateRandomLogEntryId` from production code. * kvutils: Remove `SubmissionValidator.create`, as it's only for tests. And remove default parameters for `SubmissionValidator.createForTimeMode`. * ledger-on-sql: Use the random log entry ID allocator. In Sandbox, we still use the seed service, but this is not necessary for ledger-on-sql tests. * kvutils: Make `LogEntryIdAllocator.random` an `object`. * ledger-on-sql: Move `RandomLogEntryIdAllocator` here. It's not used anywhere else. * ledger-on-sql: Add some documentation about the application code. Just to make it clear it's not used in production. 2021-07-13 20:10:30 +03:00			`# Ledger on SQL`
