Paweł Dziepak	2bcaf4309e	utils/reusable_buffer: do not warn about large allocations ... Reusable buffers are meant to be used when protocol or third-party library limiations force us to allocate large contiguous buffers. There isn't much that can be done about this so there is little point in warning about that. Fixes #3788. Message-Id: <20180928085141.6469-1-pdziepak@scylladb.com>	2018-09-30 11:12:23 +03:00
Paweł Dziepak	32ba47fb87	utils: reusable_buffer: support fragmented_temporary_buffer ... reusable_buffer already supports bytes_ostream which is often used for handling data sent from Scylla. This patch adds support for fragmented_temporary_buffer which is going to be mainly used for data received by Scylla.	2018-07-18 12:28:06 +01:00
Paweł Dziepak	b4c5e1a6d4	utils: add reusable_buffer ... This commit adds a helper class reusable_buffer which can be used to avoid excessive memory allocations of large buffers when bytes_ostream needs to be linearised. The idea is that reusable_buffer in most cases is going to be thread local so that multiple continuation chains can reuse the same large buffer.	2018-06-25 09:21:47 +01:00
