Variable | S3_STORAGE_PREFERRED_COPY_SOURCE | |
Description | Sets how to download segments from bucket storage when prefetching | |
Default | false |
Sets how LogScale chooses segments to download from bucket storage when
prefetching. If S3_STORAGE_PREFERRED_COPY_SOURCE
is
false
, the prefetcher will only download segments that
are not already on another host. Otherwise, it will download as many
segments as necessary to follow the configured replication factor. This
should help avoid excessive bucket downloads when nodes in the cluster
have lots of empty disk space.
