Hello Dmitry,

There are settings in DomainConfiguration where you can specify certain seed and cache size for particular generator. It is possible to do whether in code or in configuration file.

In code:

var domainConfiguration = new DomainConfiguration("sqlserver://localhost/DO-Tests?MultipleActiveResultSets=True");
domainConfiguration.KeyGenerators.Add(new KeyGeneratorConfiguration("Int64"){CacheSize = 128, Seed = 128});// the "-Generator" postfix is not needed

In configuration file

<domain name="Default" connectionUrl = "sqlserver://localhost/DO-Tests?MultipleActiveResultSets=True">
  <keyGenerators>
    <keyGenerator name="Int64" seed="128" cacheSize="128"/>
  </keyGenerators>
<domain>
