In this post, we recap the week's most interesting InfluxDB 0.13 and TICK-stack related issues, workarounds, how-tos and Q&A from GitHub, IRC and the InfluxDB Google Group that you might have missed. Series cardinality for a single measurement is actually the number of tag sets that exist, not just the product of the number of tag values per tag. You can use the INTO query to move data from one database to another in InfluxDB. A new DELETE series functionality has been added in InfluxDB 0.13, allowing users to delete data based on their timestamp using the WHERE clause. The new feature supports time intervals and does not drop series from the index like DROP SERIES does.
