SERVER-8431 restricted inserting a document into a collection with a text index under the following circumstances:
- The number of unique terms in the fields indexed by the text index is greater than 400,000.
- The total size of those terms is greater than 4MB.
This was done to avoid causing the server to shut down from generating a group commit larger than 512MB. However, we have since increased the journaling capacity limit to 2000MB as part of SERVER-17501. We should considering raising these limits to allows users to store more text data in a single document.
Steps to reproduce
db.foo.drop(); db.foo.createIndex({a: 'text'}); var termLength = 16; var str = ''; for (var i = 0; i < (5 * 1024 * 1024 / termLength); i++) { if (i > 0) { str += ' '; } str += i.zeroPad(termLength); } assert.writeOK(db.foo.insert({a: str}));
assert: write failed with error: { "nInserted" : 0, "writeError" : { "code" : 16733, "errmsg" : "trying to index text where term list is too big, max is 4mb _id: ObjectId('568d68d5dd2e24af1002e247')" } } _getErrorWithCode@src/mongo/shell/utils.js:23:13 doassert@src/mongo/shell/assert.js:13:14 assert.writeOK@src/mongo/shell/assert.js:414:9
