refactor(trace/api): Introduce type system for trace API

2022-06-07T13:46:53+00:00

This change updates the trace API by introducing a limited type system
for the table columns. Previously, the table columns could have any
possible type representable by the JVM. With this change, we limit the
available types to a small type system.

feat(trace/api): Add support for projecting tables

2022-05-02T13:37:04+00:00

This change adds support for projecting certain columns of a table. This
enables faster reading for tables with high number of columns.
Currently, we support projection in the Parquet-based workload formats.
Other formats are text-based and will probably not benefit much from
projection.

feat(trace): Add support for writing traces

2021-09-21T09:34:34+00:00

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.

refactor(trace): Simplify TraceFormat SPI interface

2021-09-20T20:04:23+00:00

This change simplifies the TraceFormat SPI interface by reducing the
number of interfaces that implementors need to implement to only
TraceFormat.

feat(trace): Add property for describing partition keys

refactor(trace): Add API for accessing available table columns

2021-09-12T09:27:57+00:00

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.

feat(trace): Add API for trace reading

2021-09-01T20:32:40+00:00

This change introduces a new OpenDC API for reading various trace
formats in a streaming manner.
