Also https://github.com/apache/datafusion/pull/24086 from @adriangb has some interesting experiments. Some other thoughts: * The interaction with filter pushdown is interesting - what is the best way to avoid serialization behind a large number of row filters while also minimizing bandwidth / decoding usage? The current implementation just plans the filters serially (`f1 -> f2 -> f3 -> f4 -> ... -> full projection`) without considering IO latency. * Should we just configure a fixed budget or should we do something with bandwidth? -- This is an automated message from the Apache Git Service.
