[Cassandra Wiki] Update of Cassandra2474 by JonathanEllis
Dear Wiki user, You have subscribed to a wiki page or wiki category on Cassandra Wiki for change notification. The Cassandra2474 page has been changed by JonathanEllis: http://wiki.apache.org/cassandra/Cassandra2474?action=diffrev1=5rev2=6 TableOfContents(100) + == Background == + + === Supercolumns === + + Cassandra has supported limited nesting of data within a row via SuperColumns since its initial release. A supercolumn is a named container of subcolumns, with no other metadata attached to it: unlike data columns, it cannot have a timestamp or TTL associated with it. (The one exception is that supercolumns CAN be deleted as a unit, and thus SuperColumns CAN be tombstones.) Thus, a row using supercolumns looks like this: + + ||key'''supercolumn1''' ||'''supercolumn2''' || + || ||subcolumn1||subcolumn2|||subcolumn3||subcolumn4||subcolumn5|| + + The most common use case for SuperColumns is to represent materialized views or precomputed resultsets: each object in the resultset maps to a single supercolumn. This usually takes advantage of the sorting-by-column-name to give very performant slice lookups for this resultset. To use a more concrete example, we could represent the Twitter timeline as a single supercolumn row per user, with the tweets made by that user's friends represented as supercolumns within that row. The supercolumn names will be the posted_at information, so this lets us get most recent tweets, in [reverse] chronological order easily: + + ||tjefferson'''1763''' '''1790''' '''1818''' || + || ||body ||posted_by ||body ||posted_by ||body ||posted_by|| + || ||Democracy will soon degenerate into an anarchy ||jadams||To be prepared for war is one of the most effectual means of preserving peace||gwashington||Revolution was effected before the war commenced||jadams || + ||bfranklin '''1781''' || || || || || + || ||body ||posted_by || || || || || + || ||Every government degenerates when trusted to the rulers of the people alone||tjefferson|| || || || || + + === Composite columns === + + SuperColumns have a number of limitations, most notably + + 1. there can only ever be a single level of nesting + 1. to read any subcolumn from supercolumn X, all of X is read into memory + 1. they add a lot of complexity to the Cassandra implementation and cause a fair number of bugs + + To address these problems, Cassandra added the CompositeType, which encodes a multi-value column name into a single column -- essentially the column name becomes a Tuple, for those with a background in Python. I will use Python tuple representation (x, y, z) to denote a composite column with components x, y, and z. + + Composite columns are flexible enough that there are multiple ways to encode the same data. The most natural ways to encode the above timeline data are, first, an encoding where each object becomes a single column: + + ||tjefferson||(1763, 'Democracy will soon degenerate into an anarchy', 'jadams')||(1790, 'To be prepared for war is one of the most effectual means of preserving peace', 'gwashington')||(1818, 'Revolution was effected before the war commenced', 'jadams')|| + ||bfranklin ||(1781, 'Every government degenerates when trusted to the rulers of the people alone', 'tjefferson')|| + + Note that a CompositeType definition includes type information -- (int, utf8, utf8) here -- but there is no column name information; this is governed purely by application convention. + + The main drawback to this representation is that like row keys, column names are necessarily immutable in Cassandra. So there is no way to update an object using this representation other than by deleting the old and adding the new. More subtly, this exposes us to some of the drawbacks of a pure key/value approach that normal Cassandra columns avoid: if one client updates field X in a result, while another client

Jonathan Ellis commented on CASSANDRA-2474:
---
I've updated the wiki page at http://wiki.apache.org/cassandra/Cassandra2474
with a more in-depth Background section that hopefully clears up where I'm
going with this sparse/dense business.
Eric mentioned on IRC that he's uneasy about the PRIMARY KEY syntax implicitly
using the first element of PRIMARY KEY as the row key. We could make it
explicit with another WITH option to the TRANSPOSED clause:
{{{
CREATE TABLE timeline (
user_id int,
posted_at uuid,
column string,
value blob,
PRIMARY KEY(user_id, posted_at)
) TRANSPOSED WITH ROW KEY(user_id)
}}}
This makes things more verbose (this would be a required clause) but I'm okay
with that if consensus is that being explicit here is better.
CQL support for compound columns
Key: CASSANDRA-2474
URL: https://issues.apache.org/jira/browse/CASSANDRA-2474
Project: Cassandra
Issue Type: New Feature
Components: API, Core
Reporter: Eric Evans
Assignee: Pavel Yaskevich
Labels: cql
Fix For: 1.1
Attachments: 2474-transposed-1.PNG, 2474-transposed-raw.PNG,
2474-transposed-select-no-sparse.PNG, 2474-transposed-select.PNG,
raw_composite.txt, screenshot-1.jpg, screenshot-2.jpg
For the most part, this boils down to supporting the specification of
compound column names (the CQL syntax is colon-delimted terms), and then
teaching the decoders (drivers) to create structures from the results.

We have created the sstables with 0.8.7 and run the sstableloader from separate machine in our test environment. On same setup we replaced 0.8.7 with 1.0.x (With updated patch as mentioned in issue -3589). Time required for loading data of same size took 2x time as compared to that of 0.8.7.

ISSUE :- https://issues.apache.org/jira/browse/CASSANDRA-3589 As stated in above issue generator performance is rectified but performance of the sstableloader is still an issue. 3589 is marked as duplicate of 3618.Both issues shows resolved status.But the problem with sstableloader still exists. So opening other issue so that sstbleloader problem should not go unnoticed. FYI : We have tested the generator part with the patch given in 3589.Its Working fine.

The biggest cases were needing to support null and '' as keys, column names, and column values, however I also think the technique used to serialize Java Objects as JSON but compare as a Java object is novel.

The Cassandra2474 page has been changed by JonathanEllis: http://wiki.apache.org/cassandra/Cassandra2474?action=diffrev1=6rev2=7 To address these problems, Cassandra added the CompositeType, which encodes a multi-value column name into a single column -- essentially the column name becomes a Tuple, for those with a background in Python. I will use Python tuple representation (x, y, z) to denote a composite column with components x, y, and z. - Composite columns are flexible enough that there are multiple ways to encode the same data. The most natural ways to encode the above timeline data are, first, an encoding where each object becomes a single column: + Composite columns are flexible enough that there are multiple ways to encode the same data. The most natural ways to encode the above timeline data are, first, an encoding where each object becomes a single column, with an empty value: ||tjefferson||(1763, 'Democracy will soon degenerate into an anarchy', 'jadams')||(1790, 'To be prepared for war is one of the most effectual means of preserving peace', 'gwashington')||(1818, 'Revolution was effected before the war commenced', 'jadams')|| + || ||[empty] ||[empty] ||[empty] || ||bfranklin ||(1781, 'Every government degenerates when trusted to the rulers of the people alone', 'tjefferson')|| + || ||[empty] || - Note that a CompositeType definition includes type information -- (int, utf8, utf8) here -- but there is no column name information; this is governed purely by application convention. + (One could arbitrarily pick any column whose sort order is not important to be the column value instead, but I think it's more straightforward to treat things uniformly.) The main drawback to this representation is that like row keys, column names are necessarily immutable in Cassandra. So there is no way to update an object using this representation other than by deleting the old and adding the new. More subtly, this exposes us to some of the drawbacks of a pure key/value approach that normal Cassandra columns avoid: if one client updates field X in a result, while another client updates field Y, there will be no race when X and Y are distinct columns. But if these fields are stored as part of the same composite column then there is a race.

[jira] [Updated] (CASSANDRA-2805) Clean up mbeans that return Internal Cassandra types

Clean up mbeans that return Internal Cassandra types Key: CASSANDRA-2805 URL: https://issues.apache.org/jira/browse/CASSANDRA-2805 Project: Cassandra Issue Type: Bug Affects Versions: 0.8.1 Reporter: Nick Bailey Assignee: Nick Bailey Priority: Minor Labels: lhf Fix For: 1.1 Attachments: 0001-Don-t-return-internal-types-over-jmx.patch We need to clean up wherever we return internal cassandra objects over jmx. Namely CompactionInfo objects as well as Tokens. There may be a few other examples. This is bad for two reasons 1. You have to load the cassandra jar when querying these mbeans, which sucks. 2. Stuff breaks between versions when things are moved. For example, CASSANDRA-1610 moves the compaction related classes around. Any code querying those jmx mbeans in 0.8.0 is now broken in 0.8.2. (assuming those moves stay in the 0.8 branch) For things like CompactionInfo we should just expose more mbean methods or serialize to something standard like json. I'd like to target this for 0.8.2. Since we've already broken compatibility between 0.8.0 and 0.8.1, I'd say just fix this everywhere now. -- This message is automatically generated by JIRA.

We've also had requests to allow rebuilding an index that *has* been built, so it would be nice to kill two birds with one stone here. -- This message is automatically generated by JIRA.

[jira] [Commented] (CASSANDRA-2474) CQL support for compound columns

I've updated the wiki page at http://wiki.apache.org/cassandra/Cassandra2474
with a more in-depth Background section that hopefully clears up where I'm
going with this sparse/dense business.
Eric mentioned on IRC that he's uneasy about the PRIMARY KEY syntax implicitly
using the first element of PRIMARY KEY as the row key. We could make it
explicit with another WITH option to the TRANSPOSED clause:
{code}
CREATE TABLE timeline (
user_id int,
posted_at uuid,
column string,
value blob,
PRIMARY KEY(user_id, posted_at)
) TRANSPOSED WITH ROW KEY(user_id)
{code}
This makes things more verbose (this would be a required clause) but I'm okay
with that if consensus is that being explicit here is better.

CQL support for compound columns
Key: CASSANDRA-2474
URL: https://issues.apache.org/jira/browse/CASSANDRA-2474
Project: Cassandra
Issue Type: New Feature
Components: API, Core
Reporter: Eric Evans
Assignee: Pavel Yaskevich
Labels: cql
Fix For: 1.1
Attachments: 2474-transposed-1.PNG, 2474-transposed-raw.PNG,

For the most part, this boils down to supporting the specification of
compound column names (the CQL syntax is colon-delimted terms), and then
teaching the decoders (drivers) to create structures from the results.
