You | could probably look at the committers | (https://projects.apache.org/committee.html?cassandra) to get a | handle on where it is finding use cases. | throwaway81523 wrote: | ScyllaDB and its related parts like Seastar always struck me as | real performance-oriented programming, though it was based on | leveraging language tech (C++14 early on) that was painful. I | wonder if a nicer approach is possible nowadays. | scottcodie wrote: | I get not wanting to add yet-another-system to reduce operational | complexity but it seems more economical to use a system like | Flink to do a time windowed join and emit single records to be | written to a persistence store. The Flink time window can be | sufficiently large to encompass the disparity between ingest and | event time without much RAM consumption by using a RocksDB state | backend on the operator. Let me know if I miss something, every | use case is different :) ___________________________________________________________________ (page generated 2022-06-15 23:00 UTC)
