Description
While my clients query with compound field like
{a: x, b: y}, my mongodb server automatically started to build compound index
{a: 1, b: 1} at the same. Then my server became unresponsive for a while, which made my clients get null result when querying.
I checked the mongo log and see the following lines: "build index db.col
", happen very frequently; although I don't define that compound index.
I double checked the col index schema, and didn't find the declaration about the compound index
.
Please enlighten me, I had been checking all mongodb documents regarding to this strange behavior but found nothing. It does cause problem.
