# NanoTS
NanoTS is a super fast, embedded time series database (so, no server). It supports 1 writer per stream + an unlimited number of readers.

NanoTS chooses to pre-allocate its entire storage file, this has a number of advantages:
- You cannot fill up your servers disk with data. Set it up and forget about it
- We don't waste time & cpu creating and deleting files forever
- If you configure your writer with auto_reclaim=true (the default) you will always have the newest data

# Basics Example
```

import os
import tempfile
import time
import json
import nanots

    try:
        # 1. CREATE DATABASE - 64KB blocks, 100 blocks = ~6MB
        nanots.allocate_file("test.nts", 64*1024, 100)
        
        # 2. WRITE DATA
        writer = nanots.Writer(db_file)
