merge

问题 Definition of recursive merge strategy pulled from the git merge documentation. This can only resolve two heads using a 3-way merge algorithm. When there is more than one common ancestor that can be used for 3-way merge, it creates a merged tree of the common ancestors and uses that as the reference tree for the 3-way merge. This has been reported to result in fewer merge conflicts without causing mismerges by tests done on actual merge commits taken from Linux 2.6 kernel development history.

问题 I have a table that looks something like: AccountID, ItemID 1, 100 1, 200 2, 300 I have a proc that accepts a table value parameter which updates the Items associated with an account. We'll pass something like the following: AccountID, ItemID 3, 100 3, 200 The proc looks something like: procedure dbo.MyProc( @Items as dbo.ItemListTVP READONLY ) AS BEGIN MERGE INTO myTable as target USING @Items on (Items.AccountId = target.AccountId) AND (Items.ItemId = target.ItemId) WHEN NOT MATCHED BY

问题 Background: I'm cleaning large (cannot be held in memory) tab-delimited files. As I clean the input file, I build up a list in memory; when it gets to 1,000,000 entries (about 1GB in memory) I sort it (using the default key below) and write the list to a file. This class is for putting the sorted files back together. It works on the files I have encountered thus far. My largest case, so far, is merging 66 sorted files. Questions: Are there holes in my logic (where is it fragile)? Have I

问题 Answering this question last night, I spent a good hour trying to find a solution that didn't grow a data.frame in a for loop, without any success, so I'm curious if there's a better way to go about this problem. The general case of the problem boils down to this: Merge two data.frames Entries in either data.frame can have 0 or more matching entries in the other. We only care about entries that have 1 or more matches across both. The match function is complex involving multiple columns in
