…Marten 9.50.1 JasperFx/wolverine#5002 (from #5652). JasperFx 2.87.1 adds IEventStore.TryDescribeDatabasesAsync, the database half of TryCreateUsage, which Wolverine's agent assignment now asks for on every leader heartbeat instead of the full usage. Marten answers it from Options.Tenancy.DescribeDatabasesAsync, the same call TryCreateUsage makes for its database half. - JasperFx family 2.87.0 -> 2.87.1. - Marten 9.50.1.

For JasperFx/wolverine#5002, which came out of #5652.
JasperFx 2.87.1 adds
IEventStore.TryDescribeDatabasesAsync(), the database half ofTryCreateUsage()(JasperFx/jasperfx#1013). Wolverine's agent assignment (JasperFx/wolverine#5011) now asks for it on every leader heartbeat for every store, instead of building the full usage. The full usage reads the highest event sequence and describes every projection, subscription, event type and tag type. The default falls back to the full usage. Marten overrides it to answer straight fromOptions.Tenancy.DescribeDatabasesAsync(), the same callTryCreateUsage()makes for its database half.Changes
