TIDE log Benchmark¶
Chunk Sizes and Indices¶
We simulated "scanning" large TIDE log file with varying numbers of entries per chunk and entry sizes. By "scanning" we mean seeking to all CHNK
blocks and reading the block headers.
Number of Chunks | Number of Entries per Chunk | Size of one Entry | Filesize [GB] | "Scan" Time [s] |
---|---|---|---|---|
100 | 100 | 1,000,000 | ~ 9.4 | < 0.002 |
100 | 10,000 | 10,000 | ~ 9.4 | < 0.200 |
100 | 1,000,000 | 100 | ~ 11.0 | < 200.000 |
