Hi,

We need to enable CDC in= one of the cluster which is on DSE 5.1. We need to change below settings :=
cdc_enabled
cdc_raw_directory
cdc_total_space_in_mb
cdc_free_space_check_interval_ms

What is the va= lue you keep it for below?
cdc_total_space_in_mb<= /span>
cdc_free_space_check_i= nterval_ms

Is there any performance impact you have = seen?
Should we keep cdc_raw_directory on a= different volume than data volume?
<= /div>

Thanks
Krish
