From e8e018b9d95c7aab706c98ea909072d47fb6a94d Mon Sep 17 00:00:00 2001 From: Zachary Tong Date: Mon, 1 Jun 2020 14:58:20 -0400 Subject: [PATCH] Better description of real-memory breaker changes to aggs (#57306) The old description mentions a setting that we ended up not merging. The periodic real-memory checks are automatic and do not require the user to configure any setting. --- docs/reference/release-notes/highlights-7.7.0.asciidoc | 9 ++++----- 1 file changed, 4 insertions(+), 5 deletions(-) diff --git a/docs/reference/release-notes/highlights-7.7.0.asciidoc b/docs/reference/release-notes/highlights-7.7.0.asciidoc index 823d26dfb5471..a1b8f83578206 100644 --- a/docs/reference/release-notes/highlights-7.7.0.asciidoc +++ b/docs/reference/release-notes/highlights-7.7.0.asciidoc @@ -86,11 +86,10 @@ therefore helps interpret these results.
