Hi Marcus,

Via what means?

This information is present on the Accumulo Monitor UI already, lagging 
only by a compaction happening on relevant Tablets. You can easily look 
at this data for just about any installation.

If via code, I don't believe there is public API (stable) for requesting 
the table sizes, but the Monitor pulls this data from the 
accumulo:metadata table. You could do the same. The accumulo:metadata 
table has a reference to each file contained by a table, and with it the 
number of entries in that file. It's a simple calculation to compute the 
number of entries for a table once you can extract the number of entries 
for a single tablet.
