| Description |
|
Hi, We recently upgraded out MongoDB from community version 3.4.14 to 4.0.1 We see that the compression ratio differs for the same type of data between the version Hence we did a test and found that compression ratio drastically fell for 3.6+
Can you please suggest if any changes has to be made in the configuration of MongoDB or WiredTiger? Below is the wired tiger configuration we are using wiredTiger: Thanks, Tanveer

Version 4.0.2 is still unreleased, but it will be released in the coming months; watch for an announcement on the mongodb-announce google group. The fix is also proposed for backport into the 3.6 branch. |
