Subject: Re: Repair daily refreshed table
Hi Raul,
I cannot afford delete and then load
Hi Raul,
I cannot afford delete and then load as this will create downtime for the
record, that's why I'm upserting with TTL today()+7days as I mentioted in
my original question. And at the moment I don't have an issue either with
loading nor with access times. My question is should I repair such
If you wanted to be certain that all replicas were acknowledging receipt of the
data, then you could use ALL or EACH_QUORUM ( if you have multiple DCs) but you
must really want high consistency if you do that.
You should avoid consciously creating tombstones if possible — it ends up

Hi Rahul,
I'm already using LOCAL_QUORUM in batch process and it runs every day. As
far as I understand, because I'm overwriting whole table with new TTL,
process creates tons of thumbstones and I'm more concerned with them.
Regards,
Maxim.

Are you loading using a batch process? What’s the frequency of the data Ingest
and does it have to very fast. If not too frequent and can be a little slower,
you may consider a higher consistency to ensure data is on replicas.

on all rows. Daily there is a process which loads actual data with +7 days
TTL. Thus records which are not present in last 7 days of load expired.
Amount of these expired records are very small < 1%. I have d
