From f53c9a6b25e7b55920660bc711d1a1bdd1d1f787 Mon Sep 17 00:00:00 2001 From: Azat Khuzhin Date: Mon, 1 Feb 2021 21:02:36 +0300 Subject: [PATCH 0001/1238] Fix "Block structure mismatch" for INSERT into Distributed Add missing conversion (via ConvertingBlockInputStream) for INSERT into remote nodes (for sync insert, async insert and async batch insert), like for local nodes (in DistributedBlockOutputStream::writeBlockConverted). This is required when the structure of the Distributed table differs from the structure of the local table. And also add a warning message, to highlight this in logs (since this works slower).
