Techopedia Explains Indexing One example of indexing is the legacy Microsoft Indexing Service, which maintained an index of files on a computer or in an operating system environment. Another example is database indexing, which involves creating an index for a database structure to help expedite retr...
Columns with low cardinality, meaning they have a small number of distinct values compared to the total number of records, pose a challenge for indexing. In such cases, the index may not provide significant performance improvements as it would result in scanning a large portion of the table any...
An attribute or set of attributes used to look up records in a file is called a search key. Note that this definition of key differs from that used in primary key, candidate key, and superkey. This duplicate meaning for key is (unfortunately) well established in practice. Using our ...
Supporting secondary indexing mechanisms on a distributed database is nontrivial. Secondary indexes contain attributes which may not be the partition parameters. Many of the IMDBs use partitioned indexes. Each node will contain indexes for its own data. In this way each transaction is issued at ...
Tokenization is often employed by reducing words to their core meaning to enhance the speed at which data is retrieved, as well as reducing the number of resources needed to store the data. A cached version of a page may also be used, storing highly compressed text-only documents with HTML...
Crawl health: If the site responds quickly for a while, the limit goes up, meaning more connections can be used to crawl. If the site slows down or responds with server errors, the limit goes down, and Googlebot crawls less. Limit set by site owner in Search Console: Website owners ca...
Vector database feature: Storage Attached Indexes (SAIs) DataStax Enterprise (DSE) has long had a supplemental indexing type calledStorage Attached Indexes(SAIs). Contributed to Cassandra and adopted in Cassandra 5.0, SAI supports numeric, text, and vector data types. TheAstra DB documentationprovide...
For blocked tables, further optimization can be achieved if the data values for some columns are “clustered” meaning that they are not evenly scattered in the table but grouped in some consecutive rows. Block indexing permits to skip blocks in which no rows fulfill a conditional predicate witho...
