kailiu 1415f8820d Improve the "table stats" ... Summary: The primary motivation of the changes is to make it easier to figure out the inside of the tables. * rename "table stats" to "table properties" since now we have more than "integers" to store in the property block. * Add filter block size to the basic table properties. * Whenever a table is built, we'll log the table properties (the sample output is in Test Plan). * Make an api to expose deleted keys. Test Plan: Passed all existing test. and the sample output of table stats: ================================================================== Basic Properties ------------------------------------------------------------------ # data blocks: 1 # entries: 1 raw key size: 9 raw average key size: 9 raw value size: 9 raw average value size: 0 data block size: 25 index block size: 27 filter block size: 18 (estimated) table size: 70 filter policy: rocksdb.BuiltinBloomFilter ================================================================== User collected properties: InternalKeyPropertiesCollector ------------------------------------------------------------------ kDeletedKeys: 1 ================================================================== Reviewers: dhruba, haobo Reviewed By: dhruba CC: leveldb Differential Revision: https://reviews.facebook.net/D14187		11 years ago
