Caleb Rackliffe commented on CASSANDRA-18107: --------------------------------------------- [~ifesdjeen] I might be able to roll selecting entire partitions into this issue. (I've made a note above under "Features" for now.) > CEP-15: Multi-Partition Transaction CQL Support (Alpha -> v1) > ------------------------------------------------------------- > > Key: CASSANDRA-18107 > URL: https://issues.apache.org/jira/browse/CASSANDRA-18107 > Project: Cassandra > Issue Type: New Feature > Components: Accord, CQL/Semantics, CQL/Syntax > Reporter: Caleb Rackliffe > Assignee: Caleb Rackliffe > Priority: Normal > Fix For: 5.x > > > With CASSANDRA-17719 complete, basic/alpha CQL support for Accord is now > available in the > [cep-15-accord|https://github.com/apache/cassandra/commits/cep-15-accord] > branch. There are, however, a number of features and enhancements that we > would still like to add before we make it available to users. Here is a > summary of those items, broadly categorized: > h3. *High Priority* > *Error Messages and UX* > - Fix the element/field names in result metadata to match the user query > - Better error messages > -- Append/subtracting to/from frozen list > -- attempts to use reference in WHERE clause > -- LET using a reserved word > *Testing* > - Figure out the original intent of placeholder tests in > {{AccordIntegrationTest}} (ex. {{{}acceptInvalidationTest(){}}}) > *Features* > - Support for returning the result of an {{{}IF{}}}/condition > - Constant terms on the RHS of LET > - Support for having a reference on both LHS and RHS of {{IF}} predicates > - Support for {{{}CONTAINS{}}}, {{{}CONTAINS KEY{}}}, and {{IN}} (important > for CAS parity) > - Mixed conditional and unconditional updates > - Arithmetic operations on references in {{{}INSERT{}}}/{{{}UPDATE{}}} (ex. > INSERT INTO ks.tbl1 (k, c, v) VALUES (0, 0, a.v + 1) > - Support TTLs specified in txn updates. > - Allow partition reads in SELECT (i.e. only limit to one row on the > right-hand side of LET statements) > *Tooling* > - Remove {{reateepochunsafe}} references in {{JMXGetterCheckTest}} > *Documentation* > - JavaDoc for all new statement classes > h3. *Nice to Have* > *Domain Object Cleanup* > - Given {{Selector}} is serializable, attempt to reuse it in > {{TxnReference}} rather than hard coding data conversion cases > - Separate current current {{LET}} statement from {{{}SelectStatement{}}}, > likely as a new {{LetStatement}} that names a {{SelectStatement}} > - Explore unifying {{Operation}} and {{ReferenceOperation}} > - Include non-Row items of {{FilteredPartition}} in > {{TxnData#estimatedSizeOnHeap()}} > - Explore possibility of making {{Bound}} serializable and using it directly > in {{TxnCondition}} > - Change internal representation of {{TxnDataName}} to avoid {{String}} -> > {{ByteBuffer}} conversions > - Have {{{}TxnCondition{}}}/{{{}TxnUpdate{}}} support {{slice()}} to full > take advantage of partial state replication > - Update serialization logic to reflect CASSANDRA-18099 > *Features* > - Full JSON support > - Nested UDT support > *Documentation* > - CQL language documentation and bump the CQL language specification version > - JavaDoc for all new statement classes > - Integrate {{demo.txt}} into broader documentation somewhere or remove -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
