Performance demands of latency-sensitive applications have long been thought to be incompatible with virtualization. Such applications as distributed in-memory data management, stock trading, and high-performance computing (HPC) demand very low latency or jitter, typically of the order of up to tens of microseconds.This server has a number of databases but one smaller one, that is not used very much has a high read latency compared to other more heavily used databases. We appear to have very few queries against this database with one performing a couple of clustered index scans against a table with over 750,000 rows.
SLOG: serializable, low-latency, geo-replicated transactions Ren et al., VLDB'19. SLOG is another research system motivated by the needs of the application developer (aka, user!). Building correct applications is much easier when the system provides strict serializability guarantees.Aug 01, 2018 · PolarFS is a distributed file system with ultra-low latency and high availability, designed for the POLARDB database service, which is now available on the Alibaba Cloud. PolarFS utilizes a lightweight network stack and I/O stack in user-space, taking full advantage of the emerging techniques like RDMA, NVMe, and SPDK. TiKV is a highly scalable, low latency, and easy to use key-value database. Get Started TiKV provides both raw and ACID-compliant transactional key-value API, which is widely used in online serving services, such as the metadata storage system for object storage service, the storage system for recommendation systems, the online feature store , etc.
At the technology side, the system uses a combination of low latency languages, databases and compression techniques to achieve a large number of computations per second. The company is mainly dependent on its proprietary 'Best-Fit' algorithm to identify risky assets and instruments within a portfolio. How Is Nerve Solutions Fighting COVID
