- Jun 9, 2026 Delta-of-Delta Timestamps and XOR Float Encoding on Disk How a time series block compresses to roughly two bytes per sample using a predictable timestamp pattern and the leading zeros of consecutive floats. observability
- May 10, 2026 Page Compression: Prefix, Dictionary, and the Cost of Decoding How prefix truncation, shared dictionaries, and byte-level encoding shrink a page, why decompression sits on the critical path, and where compression defeats the buffer pool. databases
- Feb 15, 2026 Latent Diffusion and the Cost of Compressing Before Generating How moving the diffusion process into a compressed latent space changes the compute budget, what the autoencoder bottleneck removes, and which losses it silently introduces. deep learning
- Jan 23, 2026 Compression and the Real Cost of an Ingested Byte Why group varint framing makes a serialized batch compact, which codecs suit which signal, and how ingest pricing turns bytes in the wrong place into a bill. observability
- Dec 11, 2025 Columnar Layout and the Cost of Reading One Field How storing each field in its own contiguous run changes the bytes a scan touches, why homogeneous columns compress better, and what the layout gives up on point reads and updates. data engineering
- Dec 11, 2025 Compression Blocks and the Loss of Splittability Why a compressor with a shared window makes a file unreadable from the middle, how block-structured codecs restore parallel reads, and what the block size trades away. data engineering
- Nov 5, 2025 Front Coding the Term Dictionary How sharing prefixes between adjacent sorted terms compresses the dictionary, what block size has to do with random access, and where the savings actually come from. information retrieval
- Jun 24, 2025 Dictionary Encoding and the Cardinality Cliff How replacing repeated values with ordinals shrinks a column, why the win collapses as distinct values grow, and what happens to a column chunk when the dictionary outgrows its budget. data engineering
- Feb 10, 2025 Block Compression and Columnar Layout for Log Storage Why compressing a block of records beats compressing each record, how column-wise encoding exposes value locality, and what the block size trades away. observability
- Jan 26, 2025 Producer Batching, Compression, and Acknowledgment Pipelining A produce request has a fixed cost per round trip and per replica, and batching, compression, and in-flight limits each trade latency for a different part of that cost. backend systems
