Background
The time series database is mainly used for processing data with time tags (which are changed in time sequence, i.e., time-sequenced), and the data with time tags is also called time series data.
The time sequence data is mainly data collected and generated by various types of real-time monitoring, checking and analyzing equipment in the power industry, the chemical industry, the meteorological industry, geographic information and the like, and the typical characteristics of the industrial data are as follows: the generation frequency is fast (each monitoring point can generate a plurality of pieces of data within one second), the collection time is seriously depended (each piece of data requires corresponding unique time), the multi-information quantity of the measuring points is large (a conventional real-time monitoring system has thousands of monitoring points which generate data every second and generate dozens of GB data quantity every day).
In software architecture, publish-subscribe is a messaging paradigm in which a sender of a message (called a publisher) does not send the message directly to a particular recipient (called a subscriber). But rather, the published messages are classified into different categories without knowing which subscribers, if any, may be present. Likewise, a subscriber may express interest in one or more categories, receiving only interesting messages, without knowing which publishers (if any) are present.
Because the time sequence database has the problem of large data volume, time is consumed very much when the time sequence database is inquired, and most time sequence databases in the market adopt a multithread mode when the time sequence database is searched, however, when the inquiry requests are too many, the multithread mode consumes memory resources very much.
When a time sequence database is used for inquiring time sequence data, how to save threads to reduce the consumption of memory resources is a technical problem to be solved.

Example 1:
the invention relates to a time sequence data query method based on subscription and publication, which changes the query operation of time sequence data into asynchronization by a subscription and publication mode, and comprises the following steps:
s100, a calculation engine serves as a subscription point to submit a subscription request, and the subscription request is used for applying for time sequence data of a certain period of time;
s200, after monitoring a subscription request through a monitor, calling a subscription API, and updating a subscription point corresponding to the subscription request into a subscription list corresponding to topic of the applied time sequence data through the subscription API;
s300, after the acquisition point acquires the time sequence data, calling a publishing API, searching a subscription list of the time sequence corresponding to topic through the publishing API, and publishing the time sequence data to all subscription points recorded in the subscription list.
In step S100, when the database computing engine wants to obtain the time series data (including the past time period or the future time period) of a certain time period, it needs to subscribe, that is, it serves as a subscription point to submit a subscription application, and applies for the time series of the certain time period through the subscription application.
Step S200, adding the subscription points into a subscription list of the application time sequence data corresponding to the topic, wherein the subscription list is used for recording all the subscription points subscribing the time sequence data corresponding to the topic.
When the calculation engine calls the subscription API, the data of the subscriber's own point is stored in the corresponding topic. If the topic subscribed by the subscriber does not exist, then just like creating one, if it exists, the point information is added to the subscription list table of topic. The specific implementation is as follows: judging whether topic corresponding to time sequence data exists or not based on the time sequence data of a certain period of time applied by the subscription request; if the subscription point exists in the subscription list of the topic, judging whether the subscription point corresponding to the subscription request exists in the subscription list of the topic, and if not, updating the subscription point corresponding to the subscription request into the subscription list of the topic; and if the time sequence data does not exist, creating topic corresponding to the time sequence data, and updating the subscription point corresponding to the subscription application into a subscription list of the topic.
In step S300, the collection point publishes the collected time series data to all the subscription points subscribing to the time series data. The acquisition point acquires data, a publishing API is called, a subscription list of the time sequence data corresponding to the topic is searched, the time sequence data is published to all subscription points in the subscription list according to the topic, and the subscription points only need to receive the time sequence data when the time sequence data need to be used.
In this embodiment, the publishing API may send the timing data to each subscription point via a multithreading schema.
As an improvement, after the listener monitors the subscription request, the listener pushes the subscription request to the message queue, the message queue temporarily caches the subscription request, and invokes a subscription API to update the subscription point to a subscription list corresponding to topic, thereby implementing the subscription of the subscription point. The subscription request is stored through the message queue, so that the memory resource can be saved.

The listener is configured to listen for meter subscription requests. The message queue is used for receiving and caching the subscription request sent by the listener. The subscription API is used for receiving a subscription request pushed by a message queue and updating a subscription point corresponding to the subscription request into a subscription list corresponding to topic of the applied time sequence data. The acquisition points are used for acquiring time sequence data. And the publishing API is used for receiving the time sequence data collected by the collecting point, searching the subscription list of the time sequence number corresponding to topic, and publishing the time sequence data to all the subscription points recorded in the subscription list.
In the system of this embodiment, the subscription API is configured to update the subscription point corresponding to the subscription request to the subscription list corresponding to topic of the applied time series data through the following steps:
judging whether topic corresponding to time sequence data exists or not based on the time sequence data of a certain period of time applied by the subscription request; if yes, judging whether the subscription point corresponding to the subscription request exists in the subscription list of the topic, and if not, updating the subscription point corresponding to the subscription request to the subscription list of the topic; and if the time sequence data does not exist, creating a topic corresponding to the time sequence data, and updating the subscription point corresponding to the subscription application into a subscription list of the topic.
The publishing API is used for publishing the time series data to all the subscription points recorded in the subscription list through a multithreading mode.
In the system of this embodiment, the database execution engine subscribes time series data of a certain period of time, adds the information of the subscription point to a subscription list corresponding to topic of the time series data, and publishes the time series data to all the subscription points in the subscription list when the time series data comes.
