Create_time will always be NULL for all tables that are created. rocksdb_table_dictionary_format=2 (the default) means use the newer data format. All newly-created tables will have proper Create_time attribute. Downgrades are only possible if one hasn't run any DDL that re-creates a table. --- mysql-test/suite/rocksdb/include/bulk_load.inc | 4 +- .../suite/rocksdb/include/bulk_load_unsorted.inc | 4 +- mysql-test/suite/rocksdb/r/bulk_load.result | 12 +-- mysql-test/suite/rocksdb/r/bulk_load_rev_cf.result | 12 +-- .../rocksdb/r/bulk_load_rev_cf_and_data.result | 12 +-- .../suite/rocksdb/r/bulk_load_rev_data.result | 12 +-- .../suite/rocksdb/r/bulk_load_unsorted.result | 12 +-- .../suite/rocksdb/r/bulk_load_unsorted_rev.result | 12 +-- mysql-test/suite/rocksdb/r/issue255.result | 16 ++-- mysql-test/suite/rocksdb/r/rocksdb.result | 7 +- .../r/rocksdb_table_dictionary_format.result | 37 ++++++++++ .../suite/rocksdb/r/show_table_status.result | 85 +++++++++++++++++++++- mysql-test/suite/rocksdb/r/truncate_table.result | 8 +- mysql-test/suite/rocksdb/t/issue255.test | 17 +++-- mysql-test/suite/rocksdb/t/rocksdb.test | 4 +- .../rocksdb/t/rocksdb_table_dictionary_format.test | 67 +++++++++++++++++ mysql-test/suite/rocksdb/t/show_table_status.test | 81 ++++++++++++++++++++- mysql-test/suite/rocksdb/t/truncate_table.test | 8 +- .../r/rocksdb_table_dictionary_format_basic.result | 14 ++++ .../t/rocksdb_table_dictionary_format_basic.test | 16 ++++ storage/rocksdb/ha_rocksdb.cc | 53 ++++++++++++++ storage/rocksdb/ha_rocksdb.h | 1 + storage/rocksdb/rdb_datadic.cc | 57 ++++++++++++--- storage/rocksdb/rdb_datadic.h | 36 ++++++++- 24 files changed, 502 insertions(+), 85 deletions(-) diff --git a/mysql-test/suite/rocksdb/include/bulk_load.inc b/mysql-test/suite/rocksdb/include/bulk_load.inc index 1b79825e507..7e163602202 100644 --- a/mysql-test/suite/rocksdb/include/bulk_load.inc +++ b/mysql-test/suite/rocksdb/include/bulk_load.inc @@ -121,12 +121,12 @@ set rocksdb_bulk_load=0;
