Did you mean to ask how much does each row/record typically take and want to estimate the volume size to provision?
u
If there is anyway to measure the volume size based on the number of spans that would be great!
s
It entirely depends on the avg number of attributes your spans have. Ingest some data and look at the table size https://kb.altinity.com/altinity-kb-useful-queries/altinity-kb-database-size-table-column-size/

Got it, thank you !
When I configure cold storage, do you know if clickhouse will automatically move the data to cold storage when don’t have enough space but the retention period not reached?
s
No, that doesn’t happen by default. You need to set up
move_factor
in policy. Please read about
move_factor
ratio in ClickHouse storage policies.
