Michael Hackstein 37a4ecfbb3 Modified the IndexIterator API to return TRI_doc_mptr_t instead of *_copy_t. Index Range node now manages a list of already returned documents, making the resulting documents distinct 2015-10-06 10:45:42 +02:00
Jan Steemann 118f924598 support [*] operator 2015-10-05 19:15:22 +02:00
Michael Hackstein e55b5d59d5 Implemented IndexIterator for PrimaryIndex. The IndexBlock uses this Iterator. Still a double free as soon as the query is finished 2015-10-01 14:34:24 +02:00

Michael Hackstein 1e9c6f110b Started implementing the IndexBlock. Right now it expects an iterator for each used index that is created by an evaluated expression from the Block. Then it will go through all iterators in every get/skip some step 2015-09-28 19:30:10 +02:00
Jan Steemann 84f59d112e unified index use checks 2015-09-28 18:13:04 +02:00
Jan Steemann 3495816fa1 changed index signatures 2015-09-28 14:11:23 +02:00
Michael Hackstein 6a11ad28ee Adapted all indices to the new planned interface so they tell us if they can serve for a condition and present their costs 2015-09-25 10:40:04 +02:00
Michael Hackstein aefc0edae0 Added a modifyable AST node to the index can serve and block functionality of all indicies. However non of them uses it yet 2015-09-23 14:38:23 +02:00
Michael Hackstein 73077a17fc Implemented the foundation to identify indicies based on DNF Conditions. Primary is implemented as an example. Right now it is only printed that it can be used. TODO: actually use it. Other indicies 2015-09-22 15:39:07 +02:00
Michael Hackstein 26fdd92685 Updated the Primary index to new version of AssocUnique. 2015-09-03 10:16:15 +02:00
Jan Steemann 2a886e6648 some index code cleanup 2015-08-26 21:35:46 +02:00
Jan Steemann a3550e331e fixed makefiles 2015-08-26 16:17:45 +02:00

Michael Hackstein 4effa2291e Merge branch 'devel' of github.com:arangodb/arangodb into array_indexing 2015-08-26 10:41:27 +02:00
Jan Steemann f4c542795c getIndexes(true) 2015-08-26 09:48:48 +02:00
Michael Hackstein 85b58a6d8d Fixed sparse indexes 2015-08-21 14:07:32 +02:00
Michael Hackstein 4bb8508d82 Implemented a new improved version of the Array index insertion function. 2015-08-20 14:03:17 +02:00
Michael Hackstein 5c0ec7d318 Indexed my first array and was able to get it out again \o/. Unique constraint is not yet working though 2015-08-19 09:55:46 +02:00
Michael Hackstein 481a106a7d Implemented a helper function to extract all values in an array to be inserted 2015-08-18 11:37:09 +02:00
Michael Hackstein 2bcef2e03b Added a function that recursivly allocates and fills index_elements if one or more paths have to be expanded. 2015-08-18 09:09:36 +02:00
Michael Hackstein 33935db4b6 Attribtue missing will not be returned when inserting elements into the index any more. 2015-08-17 12:43:14 +02:00
Michael Hackstein 1d774ade12 Removed hash_index_element and used the unified index_element instead. Also moved allocation of a new index entry closer to the spot where it is actually filled. This allows for lazy allocation. 2015-08-17 12:43:14 +02:00
Michael Hackstein 5a5d1de7ea Moved the insertion of elements into an indox to the super class. Is only used for Skiplist and Hash. Might probably be used by other indicies later 2015-08-17 12:43:13 +02:00
Michael Hackstein 8e3e2d547d Do not push <Class const> into vector. It does not work everywhere 2015-08-17 12:43:11 +02:00
Michael Hackstein 17a8f73a06 Now the input for indexes is parsed using the new attribute parser. This means the flags for expanded Attributes are set. Also introduced a transformation function to transform an attributeName list back into a string. 2015-08-17 12:43:07 +02:00
Michael Hackstein 8fbb2739b0 The indexes can now use the new AttributeName struct which contains a flag if the attribute should be Array-Indexed. Right now this flag is hard-coded to false in all cases and not persisted. 2015-08-17 12:43:05 +02:00
Jan Steemann 38227a81f8 speed up initial edge index creation 2015-08-03 18:27:50 +02:00
