Julius Volz	44390d831d	Introduce semantic versioning. ... This introduces semantic versioning (http://semver.org/) in Prometheus: - A new VERSION file contains the semantic version string. - The "tarball" target now includes versioning and build information in the tarball name, like: "prometheus-0.1.0.linux-amd64.tar.gz". - A new "release" target allows scp-ing the versioned tarball to a remote machine (file server). - A new "tag" target allows git-tagging the current revision with the version specified in VERSION.

Matt T. Proud	b3e34c6658	Implement batch database sample curator. ... This commit introduces to Prometheus a batch database sample curator, which corroborates the high watermarks for sample series against the curation watermark table to see whether a curator of a given type needs to be run. The curator is an abstract executor, which runs various curation strategies across the database. It remarks the progress for each type of curation processor that runs for a given sample series. A curation procesor is responsible for effectuating the underlying batch changes that are request. In this commit, we introduce the CompactionProcessor, which takes several bits of runtime metadata and combine sparse sample entries in the database together to form larger groups. For instance, for a given series it would be possible to have the curator effectuate the following grouping: - Samples Older than Two Weeks: Grouped into Bunches of 10000 - Samples Older than One Week: Grouped into Bunches of 1000 - Samples Older than One Day: Grouped into Bunches of 100 - Samples Older than One Hour: Grouped into Bunches of 10 The benefits hereof of such a compaction are 1. a smaller search space in the database keyspace, 2. better employment of compression for repetious values, and 3. reduced seek times.	12 years ago
