package org.elasticsearch.index.codec.tsdb.pipeline.numeric

Encoder/decoder contracts and pipeline orchestration for numeric pipeline stages.

This package defines two families of stage contracts:

• Transform stages: TransformEncoder and TransformDecoder (combined as NumericCodecStage) modify long[] values in-place and exchange metadata through the encoding/decoding context. Concrete implementations live in the org.elasticsearch.index.codec.tsdb.pipeline.numeric.stages subpackage.
• Payload stages: PayloadEncoder and PayloadDecoder (combined as PayloadCodecStage) serialize transformed values to bytes and read them back as the terminal pipeline step.

Pipeline orchestration is provided by NumericEncodePipeline (write path) and NumericDecodePipeline (read path). The high-level API is exposed via NumericEncoder and NumericDecoder, which produce per-field NumericBlockEncoder and NumericBlockDecoder instances owning mutable per-block context.

Each stage implementation corresponds to a StageSpec and is identified by a StageId for wire-format lookup during decoding.
