Hi,
I have been experimenting with tsi1 vs inmem.
I have a number of database on the same influx instance but only two high cardinality with 300 and 500 series respectively.
The whole database is 80G, and with no queries running, using tsi1, it is running at 18G mem and 80G virtual memory!
With inmem the same database uses around 16G of memory, and almost no virtual memory.
I dropped and created a new databases when changing between the two modes.
I am exploring tsi1 as some user queries would make influx crash due to OOM.
I like influxdb, but boy does it need memory!
