* feat: add startup time to logging output This change adds a startup time counter to the output when starting up a server. The main purpose of this is to verify whether the impact of changes actually speeds up the loading of the server. * feat: Significantly decrease startup times for WAL This commit does a few important things to speedup startup times: 1. We avoid changing an Arc<str> to a String with the series key as the From<String> impl will call with_column which will then turn it into an Arc<str> again. Instead we can just call `with_column` directly and pass in the iterator without also collecting into a Vec<String> 2. We switch to using bitcode as the serialization format for the WAL. This significantly reduces startup time as this format is faster to use instead of JSON, which was eating up massive amounts of time. Part of this change involves not using the tag feature of serde as it's currently not supported by bincode 3. We also parallelize reading and deserializing the WAL files before we then apply them in order. This reduces time waiting on IO and we eagerly evaluate each spawned task in order as much as possible. This gives us about a 189% speedup over what we were doing before. Closes #25534 |
