From 36874b63a1b56eed2b8e4b47ccea0337920b84b8 Mon Sep 17 00:00:00 2001 From: Sina Mahmoodi <1591639+s1na@users.noreply.github.com> Date: Fri, 19 Aug 2022 11:14:59 +0200 Subject: [PATCH] eth/filters: add global block logs cache (#25459) This adds a cache for block logs which is shared by all filters. The cache size of is configurable using the `--cache.blocklogs` flag.
