DescriptionDocumentation Link - https://docs.atlas.mongodb.com/sizing-tier-selection#memory Hello Team, Recently, I have discussed the above document with one of WiredTiger experts and we strongly believe the below information is very misleading: WiredTiger dedicates 50% of physical RAM for the WiredTiger cache. Actually, this is not the case for Atlas M30 or lower Clusters based on the Cloud Provider Instance Size Specifications. So, we think this comment could completely confuse our customer's calculations for their working set on Atlas clusters. Therefore, could we please change it to something like this to avoid any misleading? By default, for M40 or Larger Clusters, WiredTiger dedicates 50% of physical RAM for the WiredTiger cache.

seunghyoung.lee, the existing memory information applied only to M40 or larger clusters, but did not clarify. I updated the memory information to specify the information applies to M40 or larger clusters by default. |
