We just ran into an issue, where reads were blocked due to

healthy-read-lag

limit being in pending batch writes. In our situation, we have a lot of webshops where we'd much rather give them content, that is a little outdated rather than breaking the search altogether, by not returning anything. We are considering increasing

healthy-read-lag

substantially from the default (1000) to avoid this in the future. Anyone running with a very high

health-read-lag

who experience issues with this?
