Subject visibility expression & column compression
Date Mon, 24 Aug 2015 16:58:59 GMT
Hi there,

My question is how Accumulo compression works in regards to visibility labels.

Is there any difference between "VeryLargeLargeLarge & AlsoLargeLargeLarge" and "A&B"
expressions? Will it be internally compiled to a low data consuming structure?

Same question applies to column and qualifier names. Is there any difference?

The reason for this question is simple - we are trying to find out what would be the data
utilization overhead for different approaches.
