andi db0b3d6d24 new file format 
Store values in sequences of variable length. Instead of using 8 bytes
per entry we are now using between 2 and 20 bytes. But we are also able
to store every non-negative long value.
 2016-12-27 10:24:56 +01:00
andi c5f0e8514c remove debug output 2016-12-23 19:28:11 +01:00
andi 580733d267 only store the tag specific base folder in the database 
before that we added each file (one per day and tag combination) to the
db
 2016-12-23 19:12:30 +01:00
andi 6969c8ce46 all storage files for the same tags use the same storage folder 
- added an additional data folder as first level
 2016-12-23 16:35:00 +01:00
andi 85eaee940e change directory structure 
- the tags come first, then the date, 
  e.g. "mykey=myvalue_<uuid>/2016/01/01/<uuid>"
- We do this, so that we don't have to tag each file, 
  but only the root folder. This should speed up searches
 2016-12-23 15:07:08 +01:00

andi fa4921fcc9 use custom csv writer for performance 2016-12-13 18:41:19 +01:00
andi 876520eb4c do not create a new ObjectMapper per entry 
also read value with MappingIterator.
This made reading 20-30 times faster. 
We can now read and index 100k-500k per second.
The varianz might be due to LuDB slowness.
