Akkadius: Player Profile Blob to Database Conversion
|
||||
- Summary: HUGE difference in database speeds reads/writes and 1:10 datasize difference
|
||||
- The new character storage engine unlike the character_ table before, is able to properly index data and make use of
|
||||
proper MySQL/MariaDB caching optimizations and performance has increased phenominally
|
||||
PERFORMANCE AND STATISTICS FIGURES (Varies on hardware):
|
||||
- EZ Server Character data size of 2.6GB `character_` table alone now takes up approx 600MB
|
||||
- Character Data Loads take approx .03 seconds BEFORE MySQL/MariaDB cache
|
||||
- Character Data Loads take approx .001-.0035 seconds AFTER MySQL/MariaDB cache
|
||||
- Character Data Saves take approx .0001 - .003 for any particular save operation
|
||||
- Database Auto Conversion: When the 'character_' table exists, World boot-up will queue an auto-conversion prompt and convert all of your characters, BACKUP
|
||||
YOUR DATABASE BEFORE CONVERTING, here is an EASY backup script: http://wiki.eqemulator.org/p?MySQL_DB_Backup_Script
|
||||
- On auto conversion, the following tables are created automatically:
|
||||
- Table: `character_skills` - Stores Character Skills
|
||||
- Table: `character_languages` - Stores Character Language
|
||||
- Table: `character_bind` - Stores Character Bind point and Home Bind point designated by is_home bool field
|
||||
- Table: `character_alternate_abilities` - Stores all Character AA
|
||||
- Table: `character_currency` - Stores all Platinum/Gold/Silver/Copper and character related currencies
|
||||
- Table: `character_data` - Stores basic character data (Fields from `character_` table migrated to this table)
|
||||
- Table: `character_spells` - Stores character spells
|
||||
- Table: `character_memmed_spells` - Stores character memorized spells
|
||||
- Table: `character_disciplines` - Stores character disciplines
|
||||
- Table: `character_material` - Stores character armor dye textures
|
||||
- Table: `character_tribute` - Stores character tributes
|
||||
- Table: `character_bandolier` - Stores character bandoliers
|
||||
- Table: `character_inspect_messages` - Stores character inspection messages (Moved from `character_` table)
|
||||
- Table: `character_leadership_abilities` - Stores character Leadership AAs
|
||||
- Loads: Majority of Player profile loads now occur at Client::Handle_Connect_OP_ZoneEntry
|
||||
LoadCharacterFactionValues(uint32 character_id, faction_map & val_list);
|
||||
LoadCharacterSpellBook(uint32 character_id, PlayerProfile_Struct* pp);

|
||||

|
||||
- Saves: Occur all over the code now instead of calling full saves
|
||||
SaveCharacterBindPoint(uint32 character_id, uint32 zone_id, uint32 instance_id, float x, float y, float z, float heading, uint8 is_home);
|
||||
SaveCharacterCurrency(uint32 character_id, PlayerProfile_Struct* pp);
|
||||
SaveCharacterData(uint32 character_id, uint32 account_id, PlayerProfile_Struct* pp, ExtendedProfile_Struct* m_epp);
|
||||
SaveCharacterAA(uint32 character_id, uint32 aa_id, uint32 current_level);
|
||||
SaveCharacterSpell(uint32 character_id, uint32 spell_id, uint32 slot_id);
|
||||
SaveCharacterMemorizedSpell(uint32 character_id, uint32 spell_id, uint32 slot_id);
|
||||

|
||||

|
||||

|
||||

|
||||
SaveCharacterTribute(uint32 character_id, PlayerProfile_Struct* pp);
|
||||
SaveCharacterBandolier(uint32 character_id, uint8 bandolier_id, uint8 bandolier_slot, uint32 item_id, uint32 icon, const char* bandolier_name);
|
||||
SaveCharacterPotionBelt(uint32 character_id, uint8 potion_id, uint32 item_id, uint32 icon);
|
||||
SaveCharacterLeadershipAA(uint32 character_id, PlayerProfile_Struct* pp);
|
||||
- Deletes:
|
||||
DeleteCharacterSpell(uint32 character_id, uint32 spell_id, uint32 slot_id);
|
||||
DeleteCharacterMemorizedSpell(uint32 character_id, uint32 spell_id, uint32 slot_id);
|
||||
DeleteCharacterDisc(uint32 character_id, uint32 slot_id);
|
||||
DeleteCharacterBandolier(uint32 character_id, uint32 band_id);
|
||||
DeleteCharacterLeadershipAAs(uint32 character_id);
|
||||
- Now occur all over the code and only trigger when necessary
|
||||
- Two FULL saves when looting a corpse, this has been reduced to just currency saves on initial loot and trimmed to one save since AddToMoneyPP did it already
|
||||
- Every time a player moves coin with any situation (Splits/Trades/Merchant/Skills/Bank Coin Exchange/Coin Moves), a full save is made, this is now just a currency save
|
||||
- Every time a player skilled up at a skill vendor, a full blob save hit was made, this is not just a currency hit
|
||||
- Every time an AA was purchased, a full save was made
|
||||
- Every time a spell was scribed/swapped, disc was trained
|
||||
- When a client exists a zone, when a client enters a zone
|
||||
- NOTE: These amount of excessive saves have caused scalability issues that cause the `character_` table to hang which causes process hangs that affect the whole server
|
||||
because of the slowness of the `character_` table and the blob not allowing any indexing to occur
|
||||
- All functions that once depended on the `character_` table are now rewritten to appropriately read from the `character_data` table
|
||||
- Database query errors that occur during conversion or from and load/save/delete character functions are now leveraged via ThrowDBError and logs now go to
|
||||
Server_Folder_Root/eqemu_query_error_log.txt (You cannot log errors natively through MySQL)
|
||||
- DBASYNC IS NOW COMPLETELY REMOVED - This was mainly for Character data async loads/saves and merchantlist loads
|
||||
- Side implementations:
|
||||
Perl Exports:
|
||||
- quest::crosszonesetentityvariablebynpctypeid(npctype_id, id, m_var) - Sets entity variables world wide with specified npctype_id
|
||||
- quest::crosszonesignalnpcbynpctypeid(npctype_id, data) - Signals all NPC entities world wide with specified npctype_id
|
||||
- $client->GetTaskActivityDoneCount(TaskID, ActivityID) - Gets task activity done count by task id and activity id for client entity
