Methods and systems for efficient querying of time-series databases

A system comprising:

• a user interface;
• a communication interface;
• a processor;
• and
• data storage containing instructions executable by the processor for causing the system to carry out a set of functions, the set of functions including:
• receiving a query-input string for querying a time-series database, wherein the query-input string comprises a sequence of delimited character strings;
• generating a query structure based on the query-input string, wherein:
• the query structure comprises a plurality of phrases that each comprise one or more clauses that each comprise one or more segments;
• the character strings specify one or more of the segments of one or more of the clauses of one or more of the phrases;
• and
• generating the query structure based on the query-input string comprises:
• parsing the query-input string to identify the one or more specified segments;
• and
• adding the one or more specified segments to the corresponding one or more phrases of the query structure;
• submitting the query structure to a query-processing system for use in querying the time-series database;
• receiving a query result set that was obtained from the time-series database as being responsive to the submitted query structure;
• and
• outputting the received query result set for presentation via the user interface.
