Expand description

A compaction task’s StaticCompactionGroupId indicates the compaction group that all its input SSTs belong to.

Variants§

§

NewCompactionGroup = 0

Create a new compaction group.

§

SharedBuffer = 1

All shared buffer local compaction task goes to here. Meta service will never see this value. Note that currently we’ve restricted the compaction task’s input by via compact_shared_buffer_by_compaction_group

§

StateDefault = 2

All states goes to here by default.

§

MaterializedView = 3

All MVs goes to here.

§

End = 4

Larger than any StaticCompactionGroupId.
