V5 checklist

[bartelink]

Breaking change/things that are ugly queue:

• Add OpenTelemetry integration
• CosmosStore: will shift to using Azure.Cosmos when that happens. When that work might happen is subject to change. Here's an example of some teaser info.
• Cosmos: Check if newer query engine optimizations might yield a better indexing strategy, see linked article in CosmosStore: Evaluate potential indexing strategy change re new query optimizations #274 (perhaps it can borrow the one that works in DynamoDB now given this enhancement?)
• provide a way to specify a load hint that allows you to target a specific Version (or force a full Reload?)

V4 vs V3:

• StreamName -> StreamId: stores take the Category name, Decider.forStream/forRequest only take a StreamId feat!: Push StreamId out to FsCodec #419
• remove Equinox.Core ref to Equinox; remove Equinox.Core ref from Stores feat!: Move Caching into Equinox; remove Store -> Core deps #420
• migrate to IAsyncEnumerable
• changed maxAttempts and associated throwing behavior from Decider ctor to Transact's attempts argument Remove net461; target net60; reformat #310
• convert internal impl to task; expose same (but retaining Async as the primary interface in order to avoid leaking continuation token mess) Performance: Tasks / Struct #337 V4 store alignment; DeciderCore #338
• EventStoreDb: in CosmosStore, BatchingPolicy/QueryMaxItems etc are de-emphasized - perhaps same should be done for the EventStore equivalents? (e.g. EventStore.Context has an overload that requires one) V4 store alignment; DeciderCore #338
• remove explicit full FW support (libs move to netstandard2.1/net6.0 Remove net461; target net60; reformat #310
• run [tests and compilation on net6.0 Remove net461; target net60; reformat #310
• rename Equinox.EventStore.Log.Event -> Metric to match CosmosStore EventStore/SqlStreamStore: Log consistency #311
• rename Equinox.SqlStreamStore.Log.Event -> Metric to match CosmosStore EventStore/SqlStreamStore: Log consistency #311
• fixes Equinox.SqlStreamStore.Log.PropertyTag to "ssEvt" EventStore/SqlStreamStore: Log consistency #311
• adds an overload of Transact(interpret : 'state -> Async<'event list>) Rename TransactAsync -> Transact #314
• renames Decider.TransactAsync to Transact Rename TransactAsync -> Transact #314
• replaces XXXStoreCategory.FromMemento stuff with a LoadOption.FromMemento (The system that previously used this has been decommissioned, so we may consider removing it until we have realistic use case justifying its continued existence) ResolveOption/FromMemento -> LoadOption #308 later removed
• renames AsyncCacheCell -> TaskCell (and AsyncLazy -> LazyTask) Rename AsyncCacheCell to TaskCell #432

V3 breaking changes compared to V2:

• Equinox.EventStore V2 depends on EventStore.ClientApi V5.x; V3 depends on 20.6 (NOTE: EventStore Grpc and EventStore.Client 20.x require`protobuf-net 4.x whereas EventStore.Client v5.x requires protobuf-net 3.x).
• Equinox.Cosmos V2 depends on Microsoft.Azure.DocumentDb.Core V2.x whereas V3 will depend on Azure.Cosmos (aka V4) targets Microsoft.Azure.Cosmos for now, as MS have parked Azure.Cosmos (aka V4) for the foreseeable
• V2 supports full FW and/or netcore 1.x, with tools on 2.x, V3 tools are netcoreapp3.1
• V3 Changed default connection mode to Direct to match V3 SDK CosmosStore: Flip default Connection mode to Direct #281
• V3 maxItemsInTip is mandatory in CosmosStoreContext ctor Cosmos: Provide a clean way to examine endpoint Uri when working from connection string  #284
• V2 and V3 both support inhibiting certificate validation. Equinox.Cosmos V4 does not currently implement support for ignoring cert validation for e.g. use with Cosmos Simulator. Now Microsoft.Azure.Cosmos V 3.11 adds a custom HTTP factory, this could be implemented) Cosmos: Port Connector bypassCertificateValidation to V3 #236 resolves this; presumably V4 will offer similar when rebased
