summary	The content outlines various features of a tool or database designed to be developer-friendly with easy-to-write SQL queries: 1. Search Time: Allows filtering trades by specific timestamps using WHERE clause. 2. Slice Time (Sampling): - Creates time buckets from the most recent timestamp backwards in increments defined, and aggregates data over those intervals. - The process can involve calculating averages or other statistics within these sampled periods as indicated with `AVG(price)` but also has an alternative method labeled "LATEST ON" which fetches only full lines of relevant records. 3. Navigate Time: Enables querying time series from the latest values to older ones by partitioning data based on timestamps and symbols using a PARTITION BY clause alongside LATEST ON for fetching recent entries within each group as per symbol or other criteria, although it appears there might be some confusion since SELECT * FROM trades WHERE timestamp = ... is not shown here. 4. Merge Time: Joins two tables (bids with asks) based on timestamps using ASOF JOIN to match records even when the exact times don't align perfectly which facilitates real-time analysis by bringing together bid and ask data points as they happen over time, possibly for calculating spreads or other derivatives like `bid_price - ask_price`. 5. Use QuestDB: Encourages utilizing this tool due to its ease of integration with various clients/brokers/data-feeds; designed especially well in cloud environments (microservices) while maintaining high uptime. 6. Performance and Features: - Capable of handling terabytes per day at sub-millisecond query speeds, ideal for real-time applications. - Cloud-native architecture offers seamless microservice integrations along with a guaranteed 99.9% availability rate within the cloud ecosystem it operates in (e.g., Amazon Web Services). - Adheres to open standards allowing SQL queries and supports diverse data formats like Parquet or Iceberg which are commonly used for historical storage purposes. The content also implies there is additional information available, possibly a press release with more details on how this tool can meet the stringent demands of platforms such as The Central Securities Depository.
