2021-09-21	feat(trace): Add support for writing traces	Fabian Mastenbroek
	This change adds a new API for writing traces in a trace format. Currently, writing is only supported by the OpenDC VM format, but over time the other formats will also have support for writing added.
2021-09-20	refactor(trace): Simplify TraceFormat SPI interface	Fabian Mastenbroek
	This change simplifies the TraceFormat SPI interface by reducing the number of interfaces that implementors need to implement to only TraceFormat.
2021-09-20	feat(trace): Add property for describing partition keys	Fabian Mastenbroek

2021-09-20	feat(trace): Support column lookup via index	Fabian Mastenbroek
	This change adds support for looking up the column value through the column index. This enables faster lookup when processing very large traces.
2021-09-20	refactor(trace): Unify columns of different tables	Fabian Mastenbroek
	This change unifies columns of different tables used by trace formats. This concretely means that instead of having columns specific per table (e.g., RESOURCE_ID and RESOURCE_STATE_ID), with this changes these columns are shared between the tables with a single definition (RESOURCE_ID).
2021-09-19	feat(trace): Update OpenDC VM trace format	Fabian Mastenbroek
	This change optimizes the OpenDC VM trace format by removing unnecessary columns as well as optimizing the writer settings. The new implementation still supports reading the old trace format in case users run OpenDC with older workload traces.
2021-09-19	feat(trace): Add support for extended Bitbrains trace format	Fabian Mastenbroek
	This change adds support in the trace library for the extended Bitbrains format. This format is slightly different than the CSV format used by the original Bitbrains traces and contains more fields.
2021-09-12	feat(trace): Add synthetic resource table for Bitbrains format	Fabian Mastenbroek
	This change adds a synthetic resource table for the Bitbrains format, which can be used to list the available partitions in the trace.
2021-09-12	refactor(trace): Add API for accessing available table columns	Fabian Mastenbroek
	This change adds a new API to the Table interface for accessing the table columns that the table supports. This does not necessarily mean that the column will have a value for every row, but that the table format has defined this particular column.
2021-09-10	feat(trace): Support Materna traces from GWA	Fabian Mastenbroek
	This change adds support for the Materna traces from the Grid Workload Trace Archive (GWA). These traces are very similar to the Bitbrains traces, so they share the same base implementation.
2021-09-02	refactor(trace): Move Bitbrains format into separate module	Fabian Mastenbroek
	This change moves Bitbrains trace support into a separate module and adds support for the new trace api.
