Hi Devs, As I saw last week, using the "sync" write mode to write data (i.e., in Transaction Log Flusher) can lead to bad write throughput if the write buffer is small. However, I just saw "sync" write mode is in ResultState when we store the query result [1]. *Is this "sync" mode really needed on a frame-basis*? The frame size is typically 32KB, and this could lead to low throughput if a user wants to pull a lot of data out of our system. If there is no specific need for this "sync" write, I'll submit a change to fix it. Thanks!
