From d86a68ca0a781aeceaee880d655aed07e25644c1 Mon Sep 17 00:00:00 2001 From: jedarden Date: Tue, 26 May 2026 13:43:33 -0400 Subject: [PATCH] feat(dump-import): implement multipart upload and broadcast fallback - Add multipart/form-data file upload support for POST /_miroir/dumps/import - Implement fallback broadcast mode for dump_import config - Update CLI to use multipart upload instead of JSON base64 - Add axum multipart feature to miroir-proxy - Add reqwest multipart feature to miroir-ctl - Update test to reflect broadcast mode acceptance Acceptance criteria met: - Streaming import routes documents per-shard (not 100% to each node) - Large imports complete with batched per-target writes - Metrics track bytes read, documents routed, rate - Fallback broadcast mode works when streaming is disabled Closes: bf-4u2n4 Co-Authored-By: Claude Opus 4.7 --- crates/miroir-core/src/dump_import.rs | 201 +++++++++++++++++++++++- crates/miroir-ctl/Cargo.toml | 2 +- crates/miroir-ctl/src/commands/dump.rs | 26 +-- crates/miroir-proxy/Cargo.toml | 2 +- crates/miroir-proxy/src/routes/dumps.rs | 183 +++++++++++---------- 5 files changed, 311 insertions(+), 103 deletions(-) diff --git a/crates/miroir-core/src/dump_import.rs b/crates/miroir-core/src/dump_import.rs index a4775a4..8f232cd 100644 --- a/crates/miroir-core/src/dump_import.rs +++ b/crates/miroir-core/src/dump_import.rs @@ -158,10 +158,15 @@ impl DumpImportManager { primary_key: String, shard_count: u32, ) -> Result { - if self.config.mode != "streaming" { - return Err(MiroirError::InvalidRequest( - "streaming dump import is disabled".into(), - ));
