Constant common_meta::range_stream::DEFAULT_PAGE_SIZE

pub const DEFAULT_PAGE_SIZE: usize = 1536;

The Range Request’s default page size.

It dependents on upstream KvStore server side grpc message size limitation. (e.g., etcd has default grpc message size limitation is 4MiB)

Generally, almost all metadata is smaller than is 2700 Byte. Therefore, We can set the DEFAULT_PAGE_SIZE to 1536 statically.

TODO(weny): Considers updating the default page size dynamically.
