Now it is miss-leading/unclear and suggesting that > RecordSerializer should take into account synchronisation of the Buffer > that's holding. With NotThreadSafe BufferBuilder there would be clear > separation between single-threaded writing/creating a BufferBuilder and > multithreaded Buffer handling/retaining/recycling. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
