Huaxiang Sun commented on HBASE-25284:
--------------------------------------
The following text is added in the design doc.
{quote}_At the client side, a new mode (LoadBlanace) is added on top of the
existing HedgedRead mode. In HedgedRead mode, the focus is High Availability.
It cannot increase the throughput of meta query as every query goes through the
primary meta region. In the new LoadBalance mode, meta query goes to meta
replica regions first instead of the primary meta region, leaving the primary
meta region mainly serves writes and queries from hbase servers. This removes
the hotspot from the primary meta region. It increases the meta query
throughput as queries are evenly distributed N replica regions._
