From b50691e9f370983b7d3e7deada33cabaabd457a0 Mon Sep 17 00:00:00 2001 From: baunsgaard Date: Fri, 18 Mar 2022 19:13:15 +0100 Subject: [PATCH 1/2] [SYSTEMDS-3320] CLA optimize sparse combine This commit adds optimizations to the encoding combination algorithms to allow faster sparse-sparse and sparse-dense combine. [SYSTEMDS-3336] CLA Specialized maps This commit adds a few specializations to maps. MapToZero for all zero mappings. MapToCharPByte for 3 byte mappings (in between char and int). [SYSTEMDS-???] DDCFOR and SDCFOR and Sparsifying compression [SYSTEMDS-???] sparsifying compression general specialization lmm and change cost model for lmm fix cost estimator on unknown dimensions (set to 16) fix sparse TSMM in full rows CSR remove memorizer on Offsets clear soft reference in case of spark compression replace shortcut and compressed multiply cost minimum rows processed more likely to transpose MM binary no decompression fix single col table on compressed colgroup transpose size in memory if compressed is equal to compressed size if no sparse block is allocated allocate a
