Hi Qibin, Cap'n Proto supports random access within a message. One way you could do what you want is to create your file as a single large message containing a List, instead of multiple messages.
If you need to use multiple messages (say, because you write them in a streaming way), then it's up to you to create some sort of index that allows you to seek to a particular message in constant time. Cap'n Proto itself doesn't define any such indexing mechanism. -Kenton On Fri, Feb 21, 2020 at 9:52 PM Qibin Zhou <[email protected]> wrote: > Hi, > > I want to create a multi-message file and randomly access individual > messages in python.
