Hi all. I wanted to inform the tasks I worked on this week: Feb 06 - Feb 12 .
* Enhance variable names. * Add enum for neo4j protocols. * Enhance getUnionSchema method for Maps. * Implement partitons. * Activate tests: testUpdate testGetRecursive testGetDoubleRecursive testGetWebPage testGetWebPageDefaultFields Also, I started working on my C.V. My code is here: https://github.com/mgov88/gora/tree/GORA-663 Regards, Gaby El mié, 10 de feb. de 2021 a la(s) 21:33, gabriela ortiz ( arqgabyor...@gmail.com) escribió: > Hi John. > > Thanks for the feedback I will work on your comments. > > Regards, > Gaby > > > El mié, 10 de feb. de 2021 a la(s) 12:04, John Mora (jhnmora...@gmail.com) > escribió: > >> Hi Gaby >> >> Thanks for the update. >> >> BTW, I am sorry that I did not provide feedback on your code last week, I >> have been busy. >> >> Some comments: >> >> Please use more descriptive variable names: >> >> >> https://github.com/mgov88/gora/blob/GORA-663/gora-neo4j/src/main/java/org/apache/gora/neo4j/store/Neo4jStore.java#L368 >> >> https://github.com/mgov88/gora/blob/GORA-663/gora-neo4j/src/main/java/org/apache/gora/neo4j/store/Neo4jStore.java#L165 >> >> https://github.com/mgov88/gora/blob/GORA-663/gora-neo4j/src/main/java/org/apache/gora/neo4j/store/Neo4jStore.java#L171 >> >> https://github.com/mgov88/gora/blob/GORA-663/gora-neo4j/src/main/java/org/apache/gora/neo4j/store/Neo4jStore.java#L193 >> >> https://github.com/mgov88/gora/blob/GORA-663/gora-neo4j/src/main/java/org/apache/gora/neo4j/store/Neo4jStore.java#L194 >> >> https://github.com/mgov88/gora/blob/GORA-663/gora-neo4j/src/main/java/org/apache/gora/neo4j/store/Neo4jStore.java#L200 >> >> https://github.com/mgov88/gora/blob/GORA-663/gora-neo4j/src/main/java/org/apache/gora/neo4j/store/Neo4jStore.java#L206 >> >> https://github.com/mgov88/gora/blob/GORA-663/gora-neo4j/src/main/java/org/apache/gora/neo4j/store/Neo4jStore.java#L216 >> >> https://github.com/mgov88/gora/blob/GORA-663/gora-neo4j/src/main/java/org/apache/gora/neo4j/store/Neo4jStore.java#L216 >> >> Typo: >> >> https://github.com/mgov88/gora/blob/GORA-663/gora-neo4j/src/main/java/org/apache/gora/neo4j/store/Neo4jStore.java#L216 >> >> Avoid string concatenation: >> >> https://github.com/mgov88/gora/blob/GORA-663/gora-neo4j/src/main/java/org/apache/gora/neo4j/store/Neo4jStore.java#L307 >> >> Use an Enum instead of string literals, >> >> https://github.com/mgov88/gora/blob/GORA-663/gora-neo4j/src/main/java/org/apache/gora/neo4j/store/Neo4jStore.java#L129 >> >> >> regards >> John >> >> El lun, 8 feb 2021 a las 2:08, gabriela ortiz (<arqgabyor...@gmail.com>) >> escribió: >> >>> Hi all. >>> >>> I wanted to inform the tasks I worked on this week: Jan 30 -
