// This test creates a large projection, which causes a set of field names to
|
|
// be stored in a StringMap (based on UnorderedFastKeyTable). The hash table
|
|
// starts with 20 slots, but must be grown repeatedly to hold the complete set
|
|
// of fields. This test verifies that we can grow the hash table repeatedly
|
|
// with no failures.

// Related to SERVER-9824.
