[jira] [Work logged] (BEAM-4361) Document usage of HBase TableSnapshotInputFormat

     [ https://issues.apache.org/jira/browse/BEAM-4361?focusedWorklogId=104650&page=com.atlassian.jira.plugin.system.issuetabpanels:worklog-tabpanel#worklog-104650 ]

      Work Description: timrobertson100 opened a new pull request #445: [BEAM-4361] Document usage of HBase TableSnapshotInputFormat
URL: https://github.com/apache/beam-site/pull/445
 
 
   Provides documentation of how to use the `TableSnapshotInputFormat` for reading HBase snapshots.  This is a common read pattern in HBase especially when one wishes to keep load off a cluster (bypasses region servers so no GC etc) or when doing analysis on historical data which is held as snapshots.
   
   CC @iemejia @aaltay - perhaps one of you could review this please?

> Add a paragraph demonstrating the usage of {{TableSnapshotInputFormat}} as a mechanism for doing efficient full scans over HBase to https://beam.apache.org/documentation/io/built-in/hadoop/
> Typically in MR / Spark this yields up to 3-4x improvement over hitting region servers directly and keeps load (GC etc) from those services.
> I have it tested and an example ready.
