His longeting some HBase useful tools and features

1. HBase stores pictures, documents and other byte stream content

https://issues.apache.org/jira/browse/HBASE-11339

2. Speed ​​control of compact

https://issues.apache.org/jira/browse/HBASE-8329

3. A question about scan forced control timeout is quite similar to Add a heartbeat to scan itself

https://issues.apache.org/jira/browse/HBASE-13090

4. When executing the BULK Load of HBase, if The import failed, but if the WAL is written, it is considered successful. This is a BUG

https://issues.apache.org/jira/browse/HBASE-15425

5, finally We need to take action to solve the monitoring problem. Collect monitoring. The previous monitoring is limited by the number of rs.

6. Transmit all error stack information for some codes of set batch

https://issues.apache.org/jira/browse/HBASE-15711

7. Add admin Some permission control of actions

https://issues.apache.org/jira/browse/HBASE-15388

https://issues.apache.org/jira/browse/ HBASE-15128

8. Control of table permissions

https://issues.apache.org/jira/browse/HBASE-14809

9. Create multiple backups to achieve separation of reads and writes, and speed up reading, a bit specific to kudu

https://issues.apache.org/jira/browse/HBASE-1007 0

1 Large column Long-term update of some useful tools and features of HBase 0, non-stop service update configuration

https://issues.apache.org/jira/browse/ HBASE-12147

11, single-column cluster flush

https://issues.apache.org/jira/browse/HBASE-10201

12, single The time range of the column cluster scan

https://issues.apache.org/jira/browse/HBASE-14355

13. An older feature is the real-time increase of the table Backup, but it has been unstable. It is not recommended to use it online

Some key development plans of HBase2018

System optimization new feature list

?Multi-version client compatibility

p>

?Region Assign process optimization

? The external storage of the cache is realized through the off-heap read cache BucketCache and Memstore off-heap storage

?In-Memory Compact

? Control the table size through namespace

? The communication between Server and Client abandoned the previous consumer mode + queue + thread pool method, and changed to use Netty

? Realize asynchronous writing of DFS Client

? Support medium object storage (small pictures, documents, etc.)

? Realize full backup through Snapshot+Replication< /p>

? Use WAL to directly convert to Hfile to achieve incremental backup

?Realize multi-tenant solution through the physical isolation of RegionServer

?Spark on Hbase solution

?Support for multi-language clients

?Asynchronous Client call

? Use G1 recycling instead of CMS
