The shard is the basic unit to read and write logs in each Logstore. You can specify the number of shards in each Logstore. Each shard has certain service capacities:
  • Write: 5 MB/s, 500 times/s
  • Read: 10 MB/s, 100 times/s

To read data from a shard, you must specify the corresponding shard. To write data to a shard, you can use Server Load Balancer.  By using Server Load Balancer, data is  automatically written to shards based on the system load in the backend, which guarantees the high availability of log writing.
