Improved client launch performance From the start we doubled down on our efforts to improve performance and developer experience. In particular we focus on improving startup performance in serverless environments. In our quest to improve performance we identified a number of inefficiencies and resolved them.

To illustrate the difference since we be photo editing servies gan working on improving performance consider the chart below. The first graph shows the startup performance of an application deployed to a model with a relatively large architecture before we started working on improvements. The next graph shows the startup performance that we could see after we made performance improvements. The improvement. Now we will delve deeper and discuss the various changes that have brought us to such a state of great improvement. A similar protocol was previously used to communicate between the client and the query engine, based on the more efficient Wire protocol. This introduces some quirks that affect performance especially during cold.



Starts in a serverless environment. During our performance exploration we noticed that the current implementation adds considerable memory overhead especially for larger patterns. One of our solutions to mitigate this problem is to completely redesign our wired protocol. Using it we can significantly improve the efficiency of communication between the client and the query engine. We released this feature in the build with the preview feature flag. Before we start any performance improvement work, the average cold start request is shown below. Before enabling the preview feature, the chart is shown below.
