A File allocation problem is studied in this paper. The problem formulated is to minimize transmission cost where the constraints are the number of files and the number of copies. The transmission cost also reflects concurrency control cost which is essential in a distributed database system. It ...
MongoDB can perform parallel datamigrations, but a shard can participate in at most one migration at a time. For a sharded cluster withnshards, MongoDB can perform at mostn/2(rounded down) simultaneous migrations. ES对Perf impact的处理则精细很多, 通过设置cluster.routing.allocation.cluster_concur...
Data driven resource allocation for distributed learning. In Proceedings of the International Conference on Artificial Intelligence and Statistics (AISTATS), 2017. 1, 4.1.1T. Dick, M. Li, V. K. Pillutla, C. White, N. Balcan, and A. Smola. Data driven resource allocation for distributed ...
The database entropy concept is applied to a very important aspect of the analysis and design of distributed databases: the data allocation problem. The entropy of a query system and the excess entropy of a database are derived to provide powerful tools that can be used to permit the convenie...
This paper presents a stochastic model to evaluate the reliability and availability of a network service configuration consisting of a centralized database server and two distributed database server sets for a local/metropolitan area network. The centralized server monitors and controls the distributed da...

Database performance was optimized in specific scenarios when the value ofinternal_tmp_mem_storage_enginewas set toMEMORY. The compiler was upgraded to GCC 10.3. Issues resolved Errors caused by writes to a temporary file were resolved.
MatrixOne is a hyper-converged cloud & edge native distributed database with a structure that separates storage, computation, and transactions to form a consolidated HSTAP data engine. This engine enables a single database system to accommodate diverse business loads such as OLTP, OLAP, and stream...
