How does indexing internally work?

1

Hi all,

I am writing an article on Time Series storage and analysis, and I am now really focusing on Influx, as you can tell reading all my posts here.

I am deeply studying Influx internal architecture. In particular, right now I am wondering about indexing: I know that tags are automatically indexed, and that they are the only indexable part of the records. But, what happens when I insert a point? Do its tags get indexed immediately? Or indexes are periodically rebuilt on new data?

Thanks,
Luca.

There’s a pretty comprehensive two-part blog on the InfluxDB internals here that might be helpful to you.

There’s also very good documentation on the indexing here.
