When autoID is enabled, the preimport task estimates row distribution by evenly dividing the total row count (numRows) across all vchannels: `estimatedCount = numRows / vchannelNum`. However, the actual import task hashes real auto-generated IDs to determine the target vchannel. This mismatch can lead to inaccurate row distribution estimation in such corner cases: - Importing 1 row into 2 vchannels: • Preimport: 1 / 2 = 0 → both v0 and v1 are estimated to have 0 rows • Import: real autoID (e.g., 457975852966809057) hashes to v1 → actual result: v0 = 0, v1 = 1 To resolve such corner case, we now allocate at least one segment for each vchannel when autoID is enabled, ensuring all vchannels are prepared to receive data even if no rows are estimated for them. issue: https://github.com/milvus-io/milvus/issues/41759 --------- Signed-off-by: bigsheeper <yihao.dai@zilliz.com> |
