- jemalloc 11095
- On supported platforms, DuckDB replaces the system's memory allocator with jemalloc . jemalloc is statically linked into DuckDB and cannot be installed or loaded during runtime. For technical reasons, we used to distribute jemalloc as an ex
...tension. Since DuckDB 1.5.3, it is distributed as a third-party library. Operating System Support The availability of jemalloc depends on the operating system. Linux 64-bit Linux distributions of DuckDB ship with jemalloc by default (with the except...ion of builds for musl-based distributions). To disable jemalloc , build DuckDB from source and set the BUILD_JEMALLOC flag to 0 as follows: GEN=ninja BUILD_JEMALLOC=0 make This flag is p...assed to CMake as -DENABLE_JEMALLOC=0 . macOS and Windows On macOS and Windows, jemalloc is not available. DuckDB uses the system's memory allocator on these... - https://man.mtool.work/duckdb/2.0/internals/jemalloc.html
