Sharding: In the design and implementation of TDengine, a cluster has numerous nodes, Each and every node might have a number of virtual nodes (vnode), Each individual virtual node stores the data of a particular quantity of details collection points, and the data of a data collection level is usually stored in only one vnode. This way, if there are several details selection factors, the data from these information collection details might be distributed to several vnodes and dispersed in many nodes. When knowledge is ingested, the TDengine client instantly writes the info to the corresponding vnode, therefore reaching horizontal scaling of information ingestion.
This commit isn't going to belong to any department on this repository, and could belong to a fork beyond the repository.
CACHEMODEL: specifies how the newest data in subtables is saved during the cache. The default value is none.
On top of that, TDengine’s kernel and clustering function are made obtainable below an open up-supply license. The TDengine Crew is entirely dedicated to retaining this open up improvement product and thinks that no software can get the marketplace unless its Main functionalities are totally open up.
TDengine also delivers large availability on the program by virtual node group technology. Vnodes on different nodes can form a virtual node Tdengine Database group. The data In this particular virtual node group is synchronized from the Learn-Slave framework to ensure the consistency of knowledge On this Digital node group.
