Managing database operations is provided. The method comprises receiving an insert statement for a database and determining if the insert statement is for a batch insert operation or random insert operation. For a batch insert operation, responsive to determining a threshold number of specified leaf pages are missing from a memory buffer pool of the database, the database asynchronously pre-loads missing leaf pages from a corresponding index on disk into the memory buffer pool. For a random insert operation, responsive to determining a threshold number of specified leaf pages are missing from a memory buffer pool of the database, the database builds at least one memory cache index and inserts key values specified in the insert statement in the memory cache index. The memory cache index is merged with a corresponding index on disk.

Buffer pool resource allocation

A system collects statistical data for a data page, divides the data page into parts, analyzes the data page and the statistical data, based on compression efficiency of one or more compression methods for each part of each page, to determine a compression method for each part of page, and compresses, based on the analyzing, the parts of the data page.

Partitional data compression

A method includes training, by a computing device, a model to identify SQL queries; identifying, by the computing device, incoming SQL queries; grouping, by the computing device, the incoming SQL queries into groups; monitoring, by the computing device, resource usage of the incoming SQL queries in the groups; and allocating, by the computing device, resources to an SQL query of the incoming SQL queries based on the monitoring.

Query resource optimizer

Increasing index search efficiency and availability in a database is provided. An index space matrix corresponding to a plurality of mini-indices of the database is built using ordered boundary values that correspond to key value ranges of each respective mini-index to increase index search efficiency by removing redundant mini-index accesses. Mini-indices of the plurality of mini-indices are consolidated asynchronously without suspending access to the mini-indices using a particular consolidation policy of a plurality of consolidation policies that corresponds to an amount of key value overlap identified between the mini-indices. Data operations corresponding to transactions are performed using the index space matrix during consolidation of the mini-indices without suspending access to the mini-indices.

Increasing index availability in databases

An embodiment includes executing a querying process that returns database documents containing text associated with a database environment. The embodiment tokenizes the database documents into a series of n-gram tokens and groups the tokens into topic classes using natural language processing (NLP). The embodiment also generates a feature map by applying a convolution layer to an image that depicts a database structure graph of the database environment. The embodiment detects an architectural element in the image by applying a region proposal network (RPN) to the feature map and classifies the architectural element into one of the plurality of topic classes using a trained neural network. The embodiment renders, responsive to a user selection of the architectural element, an overlay depicting information about the architectural element using text and other architectural elements that are in a same topic class as the user-selected architectural element.
