" The table lists connected clients. For this the clients are stored in real table when they connect, update their statuses when needed and remove^w tombstone themselves when they disconnect. On start the whole table is cleared. This looks weird. Here's another approach (inspired by the hackathon project) that makes this table a pure virtual one. The schema is preserved so is the data returned. The benefits of doing it virtual are - no on-disk updates while processing clients - no potentially failing updates on non-failing disconnect - less usage of the global qctx thing - less calls to global storage_proxy - simpler support for thrift and alternator clients (today's table implementation doesn't track them) - the need to make virtual tables reg/unreg dynamic branch: https://github.com/xemul/scylla/tree/br-clients-virtual-table-4 tests: manual(dev), unit(dev) The manual test used 80-shards node and 1M connections from 1k different IP addresses.
