Adds BulkInsertEventsAsync to IDocumentStore, using PostgreSQL COPY binary import to bypass the normal append pipeline. Supports Guid/string stream identity, conjoined tenancy, all optional metadata columns, and archived stream partitioning. Intended for seeding, migration, and load testing. Benchmarked at ~88K events/sec (10M events in 113s) on local PostgreSQL. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
…ermutations Tests now cover every combination of: - Stream identity: AsGuid, AsString - Tenancy: Single, Conjoined - Metadata: each column in isolation (CorrelationId, CausationId, Headers, UserName), all columns combined, all columns with null values - Archived stream partitioning: on/off with each identity and tenancy combo - Batching: multiple COPY batches, batch size of 1 - Full combination: String + Conjoined + Archived + All Metadata - Version/sequence correctness assertions Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
New docs page at /events/bulk-appending covering the BulkInsertEventsAsync API: basic usage, multi-tenancy, metadata, batch size control, string identity, supported configurations, limitations, and performance notes. Includes compilable code samples in BulkAppendSamples.cs with region markers for VitePress snippet integration. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
