Hi, I was considering mvstore for time series data on a mobile device.

   - My usage would be high frequency writes (sensor data) and large batch 
   reads of ranges.
   - The schema would be key=timestamp, value=data from multiple sensors

What is unclear in my mind, is whether I should attempt the R-Tree 
implementation with dimensionality = 1, or use another implementation. More 
specifically:

   - For range queries on a key representing timestamp, is one 
   implementation better
   - For concurrent writes, is one implementation better.

My confusion stems from ambiguity in the online documentation section(s) 
"R-Tree and Pluggable Map Implementations"

"In addition to the default MVMap (multi-version map), there is a map that 
supports concurrent write operations, and a multi-version R-tree map 
implementation for spatial operations."


This implies one implementation allows concurrent writes and the other 
don't. However the next section "Concurrent Operations and Caching" says, 
without qualification:

"Concurrent reads and writes are supported."


Any other tips on storing time series would be greatly appreciated,
Thanks

-Alex
