-----------------------------
Summary: Convert proto to RSGroupInfo is costly
Key: HBASE-25705
URL: https://issues.apache.org/jira/browse/HBASE-25705
Project: HBase
Issue Type: Improvement
Components: rsgroup
Affects Versions: 2.2.3, 3.0.0-alpha-1
Reporter: mokai
Convert RSGroupProtos.RSGroupInfo to RSGroupInfo is costly if the RSGroup has
too many RSs and tables.
We can use parallelStream to handle the HBaseProtos.ServerName list and
TableProtos.TableName list in ProtubufUtil#toGroupInfo as blow.
{quote}Collection<Address> addresses = proto.getServersList()
.parallelStream()
.map(server -> Address.fromParts(server.getHostName(), server.getPort()))
.collect(Collectors.toList());
Collection<TableName> tables = proto.getTablesList()
.parallelStream()
.map(tableName -> ProtobufUtil.toTableName(tableName))
.collect(Collectors.toList());
{quote}
Get the RSGroupInfo which has 9 RS and 20k tables, the time cost reduced from
6038 ms to 684 ms.
