I am new to CockroachDB.
I have started to read the architecture document and found myself deep diving into the clock synchronization challenge. According to the documentation CockroachDB make use of Hybrid logical and physical clock while Google’s Spanner solution uses atomic and GPS based clocks to bound the clocks drift to 7ms.
I didn’t see any solution that tries to leverage PTP (1588) which provide very accurate clock synchronization.
Any reason why ? What do I miss here ?
