This commit changes the underlying storage for `Bitmap` from a
red-black tree to a roaring bitmap. It also removes bitmaps from
the cache and only stores the bitmap count.
This commit re-adds the `testdata` folder that godeps strips and
also updates the `Makefile` to add a `vendor` target that will
handle this in the future.
This commit adds the ability of the Fragment to flush the cache
bitmap IDs to disk periodically. They can then be reloaded when
the fragment is reopened.
This commit refactors the pilosa codebase. It makes several major
changes:
* Removes bitmap handles
* Removes dispatch/hold/transport
* Removes etcd dependency
* Adds consistent hash ring for slice placement
* Refactors parser/lexer
* Adds strong typing to PQL AST
* Flattens package hierarchy
This commit moves dependency management to use godep and the
new experimental vendoring support in Go 1.5.
NOTE: You must set `GO15VENDOREXPERIMENT` in your bash environment
for vendoring to work properly! See the updated `README` for details.
