> We've found that smaller guideposts are better in terms of minimizing any increase in
latency for point scans. However, this increases the amount of memory significantly when caching
the guideposts on the client. We should use a simple compression technique to mitigate this.
I noticed that Apache Parquet has a run length encoding - perhaps we can use that.
