4) nonclustered index 非聚簇索引 1. There are two types of index techniques:clustered indexes and nonclustered indexes. SQLServer中有两种索引技术:聚簇索引和非聚簇索引。5) cluster index 簇索引6) non-cluster index 非簇索引补充
indexes to the main memory of each of the plurality of nodes when the DBMS is starting up; and a remote memory storage configured to read needed data, if the needed data is not found in the local memory storage, from a remote node and store the needed data, wherein the remote node ...
This metric category represents the number of text indexes in the database fragmented beyond the warning and critical percentage thresholds specified by the user. The collection is disabled by default. Before enabling this metric and specifying a metric threshold for the number of text indexes, the...
A private subnetwork does not have direct access to the global Internet, so only those servers located in the same region and the same VPC will be able to connect to the DBMS directly, as if via a local network. This creates additional protection against intrusion for both regular servers ...
daily backup. This might require a switchover. Having the logical hosts mastered by alternate servers on different days (possibly as the result of a takeover) could cause Solstice Backup to become confused upon attempting a recover operation, due to the way Solstice Backup stores client indexes....
in the art, it will not be described in detail. The lock manager in the distributed database manager maintains locks for both pages and database objects (such as indexes, tables and rows). The distributed database manager ensures that access to data nodes in the cluster is properly ...
In 2013, Cloud computing is a jargon term without a commonly accepted non-ambiguous scientific or technical definition. (Anything that is not on your computer, e.g.: gmail) In 2016, Proponents claim that cloud computing allows companies to avoid upfront infrastructure costs, and focus on projec...
There are two types of index techniques:clustered indexes and nonclustered indexes. SQLServer中有两种索引技术:聚簇索引和非聚簇索引。3) Nonclustered index access 非簇索引访问4) clustering index 聚簇索引 1. We propose a hybrid index structure based on clustering index and B+ tree, which de...
each of the plurality of nodes; Wherein the main memory of each of the plurality of nodes includes a local memory storage unit for storing data of all memory tables and all memory indexes when the DBMS is loaded, And a remote memory storing unit for reading and storing the necessary data...
in the main memory unit of each node includes a local memory storage part loading data of all memory tables and all memory indexes, while driving the DBMS; and a remote memory storage part reading and storing the required data from a remote node when the required data is not found in the...
