Replace InfluxDB with QuestDB

QuestDB is positioned as an open-source time-series database optimized for high-performance workloads, offering ultra-low latency and high ingestion throughput. It now supports the InfluxDB Line Protocol (ILP) over HTTP, enabling it to serve as a seamless drop-in replacement for InfluxDB, which has been the leader in time-series databases. This addition aims to simplify migration by allowing teams to update existing InfluxDB clients with minimal code changes, facilitating performance and cost efficiencies. QuestDB and InfluxDB both use columnar data structures but differ in their storage architectures, with QuestDB employing vector-based append-only column files to optimize read and write operations. While QuestDB supports SQL analytics, which is widely recognized for its ease and power, it is still emerging compared to InfluxDB's mature ecosystem. Some limitations remain, such as incomplete transactionality and the absence of full authentication features. Despite these, QuestDB offers a compelling alternative for teams facing scaling challenges or high infrastructure costs, aiming to streamline the migration process while promising significant performance gains.
