Constructor Detail

TsBlockBuilder

public TsBlockBuilder(List<TSDataType> types)

Create a TsBlockBuilder with given types.

A TsBlockBuilder instance created with this constructor has no estimation about bytes per entry, therefore it can resize frequently while appending new rows.

This constructor should only be used to get the initial TsBlockBuilder. Once the TsBlockBuilder is full use reset() or createTsBlockBuilderLike() to create a new TsBlockBuilder instance with its size estimated based on previous data.
