High density time-series data indexing and compression

A method for data indexing, comprising:

• indexing the time-series columnar-based information comprising a set of time-based partitions into a set of files, the set of files comprising a first file, a second file, and a third file, the first file including a set of data strings seen in a column during indexing of the information together with byte-range data configured to selectively retrieve data from the second and third files, the second file storing column data seen during the indexing, and the third file containing a list structure for each data string in the first file, wherein the column data is stored in the second file in contiguous byte-ranges;
• and
• transferring the set of files for storage in a cloud-based object store.

A computer program product in a non-transitory computer-readable medium, the computer program product comprising program code executed in one or more hardware processors and configured to provide data indexing, the program code comprising code configured to:

• index the time-series columnar-based information comprising a set of time-based partitions into a set of files, the set of files comprising a first file, a second file, and a third file, the first file including a set of data strings seen in a column during indexing of the information together with byte-range data configured to selectively retrieve data from the second and third files, the second file storing column data seen during the indexing, and the third file containing a list structure for each data string in the first file, wherein the column data is stored in the second file in contiguous byte-ranges;
• and
• transfer the set of files for storage in a cloud-based object store.
