org.spf4j.perf.tsdb.TimeSeriesDatabase

All Implemented Interfaces:

Closeable, AutoCloseable

Deprecated.

@Deprecated
public final class TimeSeriesDatabase
extends Object
implements Closeable

Yet another time series database. Why? because all the other ts databases had various constraints that restrict the functionality I can add to spf4j. Initial Features: 1. measurements can be added dynamically anytime to a database. 2. long measurement names. 3. the stored interval is not known from the beginning. 4. implementation biased towards write performance. Format: Header: TSDB[version:int][metadata:bytes] Table of Contents: firstTableInfoPtr, lastTableInfoPtr TableInfo: DataFragment: ...... ...... TableInfo: DataFragment: EOF
