Re: snapshot transaction isolation

+1 This should help us with IGFS performance as we currently use getAll() in PESSIMISTIC mode mainly to lock keys, not to get their values. On Thu, Feb 4, 2016 at 12:56 PM, Alexey Goncharuk < alexey.goncha...@gmail.com> wrote: > So, basically, we want to add lockAll() method that locks entries

Re: snapshot transaction isolation

In PESSIMISTIC transaction a value is always read after a lock is acquired, so a locked value cannot be updated. Am I missing something? Do you have a specific scenario in mind?

So, basically, we want to add lockAll() method that locks entries without returning their values to a client - this is a good idea. I do not want, however, to call it SNAPSHOT isolation, because this is not what it is.

Re: Transformers in SCAN queries

Val, >From my point of view, special query class that allows transforming is confusing. Two points about it: 1. ScanTransformQuery will duplicate ScanQuery code with all drawbacks that we have. Moreover, any fix for ScanQuery should be repeated for ScanTransformQuery. It will lead to bugs. DRY.

Injections in entry processor

Igniters, I noticed that we don't inject resources to entry processors. This doesn't look consistent, because do this everywhere else (closures, jobs, listeners, etc.). But at the same time I believe it will cause performance degradation, because we will have to inject on each operation. Any

If all keys are known in advance, how is it different from starting a pessimistic transaction and invoking getAll() on those keys? Introducing a new concept with such restrictions does not makes sense to me. 2016-02-04 1:27 GMT+03:00 Dmitriy Setrakyan : > Igniters, > > I

Re: Transformers in SCAN queries

I don't like the idea of having additional method *query(Query qry, Transformer transfomer); *because I don't see how these transformers will work for example with SQL, but this API makes you think that transformers are supported for all the query types. Sergi 2016-02-04 16:46 GMT+03:00

Re: Transformers in SCAN queries

I think scan query implementation can be more complex than just sending closures to all nodes. e.g. it should handle topology changes. IMO it is not good idea to use compute instead of queries. On Thu, Feb 4, 2016 at 10:55 AM, Dmitriy Setrakyan wrote: > On Wed, Feb 3,

Re: Transformers in SCAN queries

Another perhaps bigger problem with running queries (including scan queries) using closures was discussed at length on the @dev not so long ago. It has to do with partitions migration due to cluster topology changes which may result in the query returning incomplete result. And while it is
