Release v0.3.0 (#464) 2018-12-04 16:50:11 +03:00
Brian Brazil fc99b8bb3a Make index reader postings nested. 
This reduces memory by only having to store the string's 16
bytes+map overheard once per label name, rather than duplicating it in every
entry for the label value.

Brian Brazil c93e261466 Reduce memory taken up by posting/symbol tables. 
Reuse the string already allocated for symbols
in the posting tables.

Use a slice for symbols in v2 format.

Move symbol size logic into the index code.
Avoid duplication of lookupSymbol logic.
