If it’s write latency it’s probably GC, if it’s read is probably IO or data

It looks like the value of the 411186035495010304 column is a string, to
cassandra that’s an opaque typer we do not make partial updates to.
If you need to update the values individually they need to
nteger,
record_name text,
record_valueblob,
PRIMARY KEY (day, timestamp, record_name)
)
Store the day as MMDD and the timestamp as before, you can then do queries
like
select * from test1 where day = 20131218 and timestamp > X and timestamp < y;

It depends a little on the nature of the change, but you need some coordination
between the schema change and your code. e.g. add new column, change code to
write to it or add new column, change code to use new column and not old
column, remove old column.

It’s safe, read repair does not affect consistency. It’s designed to reduce the
