 @NotNull Chunk<? extends Values>[] valueChunkArr,
 @Nullable
 @Nullable LongChunk<? extends Values> tsChunk,
 int len)

Description copied from class: UpdateByOperator.Context

For cumulative operators only, this method will be called to pass the input chunk data to the operator and produce the output data values.

Overrides:

accumulateCumulative in class BaseObjectUpdateByOperator<BigDecimal>.Context

Parameters:

inputKeys - the keys for the input data rows (also matches the output keys)

valueChunkArr - the input data chunks needed by the operator for internal calculations

tsChunk - the timestamp chunk for the input data (if applicable)

len - the number of items in the input data chunks
