### Is your feature request related to a problem or challenge? IPC writer code used to stage ipc messages and array buffers in intermediate storage before writing them out to the final destination (writer or file). #10044 introduced an optimization to avoid this intermediate staging for record batch ipc bodies when compression was not present. We can apply the same optimization for dictionary batches which are basically a special case of record batch messages. ### Describe the solution you'd like Collect references to dictionary batch values ahead of time and do the writes directly to the writer when we don't have to apply compression. ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
