Embodiment Construction

[0047] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0048] The present invention is designed for the RowKey of HBase to meet the requirements of storage and indexing as fast as possible.

[0049] According to an embodiment of the present invention, a method for storing and indexing spatiotemporal data of HBase is provided.

[0050] Among them, spatio-temporal data refers to data with time and space information, in which time and space are key information, and may carry other relatively unimportant i...

Abstract

The invention provides a spatio-temporal data storage and indexing method based on HBase, which comprises the following steps of: 1, designing a row key RowKey rule in an HBase, including definition and format of each byte of a RowKey; 2, extracting RowKey from the spatio-temporal data according to the RowKey rule designed in the step 1; 3, writing spatiotemporal data into the HBase according to the designed row key RowKey rule; and step 4, retrieving spatio-temporal data from the HBase according to the RowKey rule. According to the method, the retrieval and aggregation speeds are increased; the HBase is used as a database, GeoHash and time are ingeniously combined in RowKey, and a proper query method is used, so that the speed of space-time query is increased. The HBase is used as a database of spatio-temporal information, the advantages of high reliability, high performance and the like are achieved, horizontal capacity expansion can also be achieved when the clustering capacity is insufficient, scenes under mass data are facilitated, and the advantages of the HBase are brought into full play.

Description

technical field [0001] The invention relates to the field of data storage, in particular to an HBase-based spatio-temporal data storage and indexing method. Background technique [0002] Driven by the rapid development of the Internet, the development momentum of the Internet of Things is also very rapid, and as 5G technology gradually matures, the Internet of Things will also usher in a new wave of development. With the continuous expansion of the scale of the Internet of Things, the resulting data volume is also increasing In rapid growth, spatio-temporal data is an important part of it. [0003] For the traditional spatio-temporal data storage and retrieval scheme, it takes a lot of time to match the longitude, latitude and time fields, and it can be used when the amount of data is small, but it is already powerless to deal with a large amount of spatio-temporal data. IoT devices with high security requirements and IoT systems with real-time spatio-temporal data are undo...
