Hello, The proposal is well written, I have no questions. We have been waiting for this feature for long time.
I am supporting it Thanks Enrico Il Mar 15 Ago 2023, 04:28 horizonzy <horizo...@apache.org> ha scritto: > Hi, everyone: > There is a proposal about batched reading( > https://github.com/apache/bookkeeper/pull/4051), to introduce it to > improve > read performance. > > The objective of this proposal is to enhance the performance of entry > reading by introducing a batch entry reading protocol that takes into > account the expected count and size of entries. > 1.
