Previously we were keeping up to around 6 hours of WAL around by removing 1/3 every hours. This was excessive, so switch to removing 2/3 which will up to around 3 hours of WAL around. This will roughly halve the size of the WAL and halve startup time for those who are I/O bound. This may increase the checkpoint size for those with certain churn patterns, but by much less than we're saving from the segments. Signed-off-by: Brian Brazil <brian.brazil@robustperception.io> |
